Our Samsung gas oven guard products are made of high-quality Teflon material, BPA/PFOA free, waterproof, heat-resistant material, can withstand high temperature up to 300 degrees without melting, burning or deforming, and can be reused. The black cooktop mat is easy to install, and can be used directly on the cooktop after opening the package, effectively protecting the cooktop, keeping your gas cooktop clean and always in pristine condition. If the protective film gets dirty accidentally during daily use, just wipe it with a towel. When it gets too dirty, you can throw it in the sink, or put it in the dishwasher. Gas Hob Hood - This is a kitchen must have!
