Opa kitchen products

Where can used pans and pots be returned to? You can place used pans and pots in a metal collection container.

Steel vessels

What is the reason for greyish white spots and stains, limestone deposits in a steel pot? Limestone and other minerals in water can, if they precipitate, form a grey coating or light stains on the bottom that cannot be removed with cleaners. Clean the bottom by soaking vinegar/water mixture (1–2 dl vinegar/1 l water) in the pot overnight. Wash and dry the pot after the treatment. Why do small light spots appear on the bottom of a steel pot? White specks appear in a pot if table salt is added before boiling. They can also be cleaned using diluted vinegar. Salt should not be added before the water is boiling. Do not store salty foods for long periods in a steel vessel because table salt causes pits in steel. What is the reason for the colours of a rainbow in a steel pot? Colours of a rainbow on steel are due to sudden temperature changes. The phenomenon is completely harmless and disappears by itself over time. If you wish, you can treat the vessel with a vinegar solution. How can I get a burnt steel pot clean? Food getting stuck hard is usually due to overtly high stove heat. Soak the pot or cook a cleaner solution with one tablespoon alkaline cleaning powder and 1 l water in it. What should I do if the handle has come off the pot lid? Opa steel pots come with a warranty of 10 years. Our customer service can tell you whether repairing or replacing the lid is more reasonable.

Coated vessels

Marks remained in a coated pan/pot right after the first use, is it ruined? The surface of a new coated vessel is velvety or reflective to make non-stick properties possible, so the first scratches/signs of use caused by utensils are more easily visible in it. This is completely normal, and the coating is not damaged in any way. Can a coated pan/pot be coated again? Unfortunately, pans or pots cannot be coated again. What is the difference between different kinds of coatings?

  • The Xylan coating of the Arki range is a PFOA-free, two-coat non-stick coating.
  • The Eclipse coating of the Valu range is a PFOA-free, three-coat non-stick coating.
  • The Creblon C3+ coating of the Kivi range is a PFOA-free non-stick coating reinforced with ceramic particles.

The more coats in the coating, the more durable it is against mechanical abrasion. Ceramic particles also reinforce the surface compared with an ordinary coating, meaning that the coating is more resistant to abrasion. Do the coatings of Opa pans contain PFOA compounds, which are classified as harmful? No coating used by Opa contains PFOA compounds. Is rinsing with hot water after use enough for a coated pan/pot? Even a coated product should be washed up immediately after use using washing-up liquid and a brush, both inside and outside. This way, stains will not stick. The coating of my pan/pot has become scratched over time, can it still be used? Pans inevitably end up with signs of use. If the scratch has not penetrated the coating so that particles come out of it, it is not harmful, but if the pan has “frayed” scratches from which coating comes off, we recommend replacing the vessel. The colour of the coating of my pan has changed/food sticks to the pan, why? If the colour of the coating has become brownish and/or food sticks to the pan, the pan has been overheated at some point. Overheating “dries up” the surface, and food begins to stick as a result. At this point, we recommend replacing the pan. Coated pans should always be used at low or medium heat settings. Why should food not be stored in a coated pan/pot? Salty and spicy foods can have a detrimental effect on the coating and thereby shorten the service life of the vessel. What is the service life of coated frying pans or pots? The service life depends a lot on how often and how the pans are used and treated. Depending on the frequency of use and care, the service life of a coated pan is 2–5 years.

Carbon steel and light cast iron pans

The black surface has come off the carbon steel pan, is it ruined? Opa’s Heavy metal carbon steel pan is not coated. The black surface on the pan is, therefore, not any material added to the pan, but the iron oxide layer created in the manufacturing process, intended to protect the pan from rust and make it easier to take into use. The black surface will wear/come off in use, and this is completely normal. It is therefore not a material or manufacturing defect covered by warranty. This phenomenon is mentioned in the user instructions, and it is recommended to season them once the black surface has worn. Why is my carbon steel pan rusting? The carbon steel pan is not a stainless material and is not coated, so it is possible that it rusts. A black oxidised layer is formed on the surface of the pan in the manufacturing process, and its purpose is to protect the pan from rust before it is taken into use. However, it wears soon in use, after which the pan easily rusts unless it is well seasoned. The pan should therefore be cared for in the same way as cast iron vessels, seasoning as necessary and avoiding the use of washing-up liquids. A rusty pan is not spoiled; you can scrub the rust off with a steel brush or wool and then season the pan. If well cared for, the pan is a great long-life cooking utensil. Why does the bottom of a carbon steel pan become warped? The material of the carbon steel pan is quite thin and, therefore it also heats quickly and occasionally can become warped if it overheats. We recommend avoiding to heat the pan when empty and use the lower power settings of the stove. The pan endures high heats, but not shock-like heating, the vessel should be heated gradually. Adding a drop of water on the pan during heating helps to prevent warping. How do I season my pan/pot? Seasoning on a stove: Clean the pan by washing it with hot water or boiling water in the pan. Scrub a few thin layers of lard or cooking oil on the inside of the hot vessel. Wait for the fat to become sucked up in the surface of the pan between spreading the layers. The fat will smoke lightly when absorbing into the surface of the pan. Finally, wipe the vessel clean of excess fat. Seasoning in an oven: Clean the pan by washing it with hot water or boiling water in the pan. Pre-heat the vessel for a short time in the oven, then apply a thin layer lard or cooking oil onto the pan surface. If you use lard for seasoning, heat the vessel in a 250°C oven for half an hour. If you use cooking oil for seasoning, heat the vessel in a 150°C oven for 1–2 hours. When using cooking oil for seasoning, you should use oil that endures heat well, such as canola oil. Finally, wipe the vessel clean of excess fat. My light cast iron pan become brownish and speckled after seasoning, is it ruined? The brownish-speckled layer of fat formed on the surface protects the vessel from rust and improves its frying properties, and it is completely normal for the surface of the pan to become speckled after it is taken into use.

Muurikka products

Muurikka Pans

How do I take a new Muurikka Pan into use? Clean the new pan by washing it with a mild cleaner or hot water and season the pan immediately after cleaning as follows: Heat the pan hot on a gas burner, electric grill or campfire and apply a thin and even layer of Muurikka Silava Frying Fat or oil throughout the pan surface. The fat must not trickle thickly onto the pan bottom, because if it lumps, the fat will burn into an uneven mass. Apply a few layers of fat and wait for the fat to suck up before applications. The fat will darken and dry onto the pan, at least at the centre of the pan. The pan will darken further in use and gain more patina. Watch the video here. How do I clean a Muurikka Pan? Always clean the pan after use. The best results are achieved by cleaning the pan immediately after use. Pour a drop of water on the pan, bring it to boil and clean the pan with a spatula and paper towel. Wipe the pan dry and grease the frying surface lightly with cooking oil or salt-free Muurikka Silava Frying Fat. Watch a video on cleaning here. When your Muurikka Pan is dirty or you want to clean the pan between dishes with different tastes, common salt is a good trick. Spread salt generously on the Muurikka Pan and keep a low heat on for a few minutes. The salt will suck up fat, moisture and stains. Once the stains have sucked up, scrape the salt off with a spatula, for example, pour a drop of water on the pan and wipe the pan clean. Last, remember to dry and grease the pan well. This way, your Muurikka Pan will be as good as new again. Watch a video on the salt trick here. What should I do if my Muurikka Pan rusts, is it spoiled? If the pan has been exposed to moisture during storage and is rusty, don’t worry. Scrub the pan with steel wool or grill brush, clean and season it according to the instructions on taking a Muurikka Pan into use. This way, your pan will be good to go again. How should I prepare a Muurikka Pan for long-term storage? Before long-term storage, clean, dry and grease the pan by heating it with Muurikka Silava Frying Fat (heating will remove moisture from the pan and Silava Frying Fat will prevent rust). Store the pan in a dry place. How do I take a new Muurikka steel Paella Pan or Wok Pan into use? The material is cold-rolled steel/carbon steel. Because the pan is not rustproof and does not have a non-stick surface treatment, it is important to carefully follow the instructions on taking into use and maintenance. A proper treatment improves the frying properties of the pan and protects it against corrosion. Remove the temporary rust prevention treatment by boiling some water on the pan and then clean the vessel with water and mild washing-up liquid. Do not leave the pan to dry outdoors; dry it right away so that it will not rust. After that, heat the pan immediately and grease the inside of the pan lightly with oil or lard. Seasoning protects the pan against rust and improves its frying properties. The seasoning must be renewed whenever it is damaged or has been washed off. The brownish-speckled layer of fat formed on the surface protects the vessel from rust and improves its frying properties, and it is normal for the surface of the pan to become speckled after it is taken into use. Watch the video here. How do I clean a Muurikka steel Paella Pan/Wok Pan? Going forward, you should not use washing-up liquids for cleaning the pan because they remove the fat layer. Wash with hot water or by boiling water in the pan. If food residues are stuck to the pan, you can soak them and/or scrub with steel wool. Store the pan wrapped in paper inside a plastic bag in a dry, sheltered place. What should I do if my steel paella pan/work pan rusts, is it spoiled? The pan is not spoiled. If the pan has become rusty, scrub and wash the rust off and repeat the seasoning process.

Muurikka Electric Smoking Ovens

The Electric Smoking Oven griddle drops off, is it the wrong size? You should place the griddle on top of the drip tray and place the drip tray on the brackets in the smoking oven. Cleaning the Electric Smoking Oven The Electric Smoking Oven is made of stainless steel. The removable inner parts, i.e. chip tray, drip tray and griddles, should be cleaned after each use. You can even wash the parts in a dishwasher. Tip! You can protect the chip and drip drays with aluminium foil, it will make cleaning easier. Especially if you use sugar cubes to add colour to fish, they easily melt onto the chip tray. We also recommend cleaning the inside of the electric smoking oven if a lot of soot and fat has accumulated on the walls. Remove the electric resistor from the smoking oven (the heating element is fixed with 1 lock nut), remove the resistor and its support from the smoker, after which you can clean the inside of the smoker with Muurikka MultiCleaner.

Tundra Grill products

What should be considered when using the Tundra Grill? When using an open fire, indoors or outdoors, practise due diligence at the cooking location, as well as note the fire safety regulations that are in force at the time. The instructions and guidelines set by the fire safety officers are always to be adhered to prior to using the product.

  • Never light a fireplace with petrol/gasoline or other similar unsuitable substances!
  • Keep ignition fluids and fire making materials out of the reach of children!
  • Never leave children alone by the fireplace!
  • Do not store flammable materials or liquids in the immediate vicinity of the bottom of the fireplace.
  • When handling hot hobs (lift-turn), grasp the appliance by its wooden handles or wear protective gloves.
  • The properties of steel in an open fire use include rapid warming, so do not touch parts that are not protected by wood. The bottom side of the fireplace and the ashpan become very hot during use.
  • Do not lean on the fireplace or smoke hood.
  • Avoid burning disposable containers, plastic, cardboard, etc. in the fireplace, which can produce and disperse flammable flakes into the surroundings.
  • Only burn birch and alder, do not burn other tree types.
  • The maximum height of the flames must not exceed half the distance between the firepit and bottom of the smoke hood.
  • Be sure to fasten the fireplace to the base, have fire extinguisher equipment available, and instruct others on how to act during an emergency.
  • Do not start cooking until the surface of the materials in the firepit are covered in ash.

Does the Tundra Grill always need to be placed on a non-combustible surface? There must be a non-combustible surface such as tile, gravel or sand under the Tundra Grill and extending out for 500 mm around the edges fireplace. If the Tundra Grill is installed on a wooden terrace, for example, a protective metal sheet must be installed under the Tundra Grill. The Tundra Grill protective mat is made of material that will not ignite easily, but not completely non-combustible. The protective mat is primarily intended to protect vicinity of the Tundra Grill from splashes during cooking. Especially when installing on the terrace, special care must be taken to ensure that the burning coal cannot fall under the terrace in between the decking. What type of Tundra Grill is best suited for which space? E.g. terrace / interior / yard? The Tundra Grill Notski is designed to match the likeness of a campfire site, which is why we do not recommend installing Notski indoors. When used indoords the Tundra Grill needs a smoke hood and a chimney so that the smoke goes up the chimney and is not left to circulate indoors. Otherwise, any other Tundra Grill model is suitable both outside and inside. What should be the distance from the Tundra Grill to combustible materials? Non-combustible surface such as tile, gravel or sand under the Tundra Grill and extending out for 500 mm around the edges fireplace. In addition, the protective distance to the sides of 1500 mm from the center of the fireplace in all directions. How is replacement air handled? The best and draft-free way to solve the correct flow of replacement air required by an open fire is to build a tight radially framed floor in the structure, which is left open from under the floorboards. A hole of 25–30 cm is made under the fireplace, from which the air flow rises directly into the grate; this results in a good, steady air flow inwards. When the fire is burned, the flow accelerates and thus a good upward draft is created into the chimney. Another popular, but not so good way to solve the supply of replacement air is to immerse replacement air pipes in the foundations of the building. The pipes should be about 150 mm in diameter and at least 4 should be installed to point in different compass-points. To achieve good air flow and operability, the position of the pipes should be pointed upwards, as much as possible, towards the fireplace. No proper air flow is achieved using horizontal piping. Is it possible to burn any tree type in the Tundra Grill? Only birch or alder may be burned in the Tundra Grill. Do not burn disposable containers, plastic, cardboard, etc. in the Tundra Grill, which can produce and disperse flammable flakes into the surroundings. Can the Tundra Grill be used outdoors under the sky, without a covering/hood? Yes. Can you get a new base for the Tundra Grill when the old one is worn out? Yes. The replacement base is available for the Tundra Grill models 80, 100 and BBQ. Can the Tundra Grill’s protective mat be used as fire protection in the outdoor hut instead of a metal sheet? Depends on what floor material is used in the hut. There must be a non-combustible surface such as tile, gravel or sand on the floor below the Tundra Grill and extending out for 500 mm around the edges fireplace. If the Tundra Grill is installed on a wooden floor, for example, a protective metal sheet must be installed under the Tundra Grill. The Tundra Grill protective mat is made of material that will not ignite easily, but not completely non-combustible. The protective mat is primarily intended to protect vicinity of the Tundra Grill from splashes during cooking. How well does the Tundra Grill handle the changing weather conditions when it is placed outdoors without any cover? How to store the Tundra Grill over the winter months? The Tundra Grill handles the outdoors without a cover just fine, but it requires careful maintenance after each use. After use, always thoroughly clean the firepit of the Tundra Grill from ashes. Make sure that the charcoal has been extinguished before cleaning and that there is no risk of fire from smoldering or other combustible material. The easiest way to clean is to brush the ash through the hole in the middle of the firepit into the ashpan. Emptying the ashpan is easy, for example, into a metal bucket. Please note that the ashpan may be hot, use a pot holder to lift the ashpan. It is also a good idea to clean other surfaces of the Tundra Grill, such as the smoke hood, frying hobs and the foot section. A damp cleaning cloth can be used for cleaning. If there is stuck on dirt on the surfaces, a small drop of detergent can be mixed into the cleaning water. If, despite maintenance, your Tundra Grill develops scratches or paint wears off in places, we recommend that you repair the worn paint surface with Tundra Grill Touch-up paint as soon as possible. First clean the area to be repainted thoroughly of soot and grease, and allow to dry. If the worn area has already rusted, thoroughly clean the rust before painting. Treat the clean and dry area with Thundra Grill Touch-up paint according to the instructions on the packaging. If your Tundra Grill is not used for a long time, you can lightly coat the fireplace with cooking oil. The oil forms an anti-rust layer on the surface. We recommend the use of the Tundra Grill Protective hood, especially when it is placed outdoors without any other cover from the elements. The protective hood protects the Tundra Grill from dirt and inclement weather conditions. However, a protective hood is not a substitute for proper maintenance.
