- I have an electric oven with no exposed heating element; can I use the Ovenliner on the floor of my oven?
No. The instructions specifically state to locate the Ovenliner on the lower rack of your oven. The element in your oven is located directly underneath the floor of your oven. This creates the highest levels of heat on the bottom of your oven where temperatures can reach 700-800 degrees. At these temperatures, the Ovenliner is not guaranteed to work properly and may become soft and melt.
- I have a gas oven and the Ovenliner instructions say to place the Ovenliner on the lower rack of the oven. Why can't I place the Ovenliner on the floor of the oven?
There are two major reasons for locating the Ovenliner on the lower rack of a gas oven. First, the flames of a gas oven can bring the floor temperature of the oven to an unsafe temperature range that is too hot for the liner and may cause the liner to melt. Second, placing the Ovenliner on the lower rack prevents vents on the oven floor from being covered. Consumers should never cover these vents because it can create unsafe carbon monoxide levels that could be harmful to you. Placing the liner on the lower rack will allow the heat to circulate and keep these vents from being inadvertently blocked. The Ovenliner will still catch all the spills and keep them from getting baked onto the bottom of your oven. You may place your baking pans directly on the Ovenliner, so that you don't lose any oven space.
- Is the Ovenliner safe to use in convection ovens?
Yes. The Ovenliner is safe for convection ovens. For proper placement, determine the type of oven and then follow the use and care instructions that came with the Ovenliner.
- If I place the liner on the lower rack of the oven, won't I lose a rack for baking?
No. Place your baking pans directly on top of the Ovenliner. The Ovenliner will still keep all the spillovers and baked on foods from adhering to the bottom of your oven for easy clean up every time.
- Will the Ovenliner keep my food from cooking evenly or take my food longer to cook?
No. Regardless if the Ovenliner is on the bottom of your oven or on the bottom rack of your oven, you do not need to change the way you cook. The Ovenliner will efficiently transfer the air and heat in your oven. There is no need to cook foods longer or worry about the food not cooking evenly. Your oven will perform the same as it did before you used the Ovenliner. Only now all the spillovers and burnt on food will be caught by the Ovenliner and not the floor of your oven.
- How do I clean the Ovenliner?
The Ovenliner is dishwasher safe or it can be washed in warm, soapy water and wiped dry with a soft cloth.
- How do I prolong the life of the Ovenliner?
To preserve the nonstick qualities do not use abrasive cleaners, sharp implements or fold the Ovenliner.
- After using the Ovenliner it has now changed color. Will it still work?
Yes. The Ovenliner may change in color after use but it will not affect its performance. The Ovenliner will still catch all the spills and keep them from getting baked onto the bottom of your oven.
- Can I trim the Ovenliner to fit my oven?
Yes. To ensure proper heat circulation you may need to trim the Ovenliner to fit the wire rack or bottom of your oven properly. The Ovenliner should not extend over the edges of the wire rack or cover any holes inside the oven. To trim the Ovenliner use regular household scissors.
- Can I use the self-cleaning mode with the Ovenliner inside my oven?
No. You must remove the Ovenliner before operating the self cleaning mode. The Ovenliner cannot sustain temperatures above 550° F. Failure to remove the Ovenliner may cause permanent cosmetic damage to your oven's interior.
- What are the Chef's Planet Ovenliner and Bakeware liners made of?
Chef's Planet Ovenliners and Bakeware Liners are made of PTFE coated fiberglass. PTFE stands for Polytetrafluoroethylene and is a patented nonstick surface. This coated surface (PTFE) is generally known to the public by DuPont's brand name Teflon.
- Are your Bakeliners and Ovenliners made of Teflon?
In addition to DuPont, several other manufacturers like Chef's Planet make their own brands of PTFE (Polytetrafluoroethylene) for use in nonstick products. What you are familiar with by the name Teflon is the same coating used for Chef's Planet Ovenliners.
- I set my oven to self-cleaning mode and forgot to take out the Ovenliner. The liner either melted and/or turned white and now I have a white coating on the interior of my oven. Is my oven ruined?
No. Your oven will still work properly and safely. However, the white coating will cause your oven to be cosmetically altered. From our research, this coating is not removable. If you want to remove the coating, we recommend contacting your oven manufacturer to replace the inner shell of the oven. You may also continue to use the self-cleaning mode but ensure you have removed any remaining Ovenliner pieces before cleaning. The Ovenliner will continue to breakdown but will not impact the performance of the oven.
To better understand how the Ovenliner reacted in the self-cleaning mode, please read the following: In the self-cleaning mode, the oven temperature reaches 900° F to 1000° F which is beyond the guaranteed temperature for the Ovenliner. Through these extreme temperatures, the coating on the Ovenliner melted in the oven. When the oven cooled down in the self-cleaning process the coating from the Ovenliner permanently bonded to the interior of the oven.
- Can you help me make sense of the negative media I have read about Teflon and other nonstick coated products?
Recently there has been negative media about Teflon®. The media attention has been focused on a chemical used in the nonstick manufacturing process called PFOA. It has been determined that PFOA poses no danger to consumers because the chemical is only used in the manufacturing process and is not actually part of any finished products. Nonstick coated products used in kitchens are an example of these products.
- What is PFOA?
PFOA stands for perfluorooctanoic acid, a man-made chemical. Companies use PFOA to make fluoropolymers which are used in thousands of important manufacturing and industrial applications such as architectural fabrics; chemical processing piping; automotive fuel systems; telecommunications wiring insulation; and computer chip processing - in addition to consumer products such as cookware and apparel.*
- Can I be exposed to PFOA from my nonstick coated products?
No. Consumer products made with fluoropolymers include nonstick cookware, and breathable, all-weather clothing. According to the EPA, there is no risk of exposure to PFOA from the routine use of household products like nonstick cookware.*
- What is Polymer Fume Fever?
Polymer Fume Fever is a term coined to describe the flu-like symptoms that can result from direct exposure to fumes of overheated fluoropolymers, such as those found in nonstick products. If used properly, nonstick coated products pose no risk of Polymer Fume Fever.*
- Where can I find more information about PFOA?
- Are there risks to birds exposed to nonstick coatings?
It is important to understand that birds have extremely sensitive respiratory systems. Cooking fumes from any type of overheated cookware or bakeware, not just nonstick, can damage a bird's lungs. To protect birds, owners should keep birds out of the kitchen, never allow cookware and bakeware products to overheat, and ensure that their kitchen is properly ventilated at all times. Always use kitchenware products in accordance with the use & care recommendations provided with the product.
