Silpat nonstick baking sheets are made of woven glass coated with food-standard silicone. Used daily by professionals, the sheets offer multipurpose uses for preparing, cooking, and heating up food. They're also easy to clean--simply wipe them off using hot water and dish soap. Store them by either rolling them up or keeping them flat. Some silicone baking mats can withstand temperatures up to 480 degrees Fahrenheit because of the additional labor put into making the sheets durable and fit for more than one use. Silpat mats are not expected to last as long as reusable silicone baking sheets and, thus, may not be able to endure up to and exceeding 450 degrees Fahrenheit. Silpat ™ is effective in temperatures from -40°F to 500°F (or -40°C to 260°C) Easy Cleaning. Wipe the SILPAT ™ with a damp, soft sponge and then rinse with clean water. Shake to remove excess water and dry in open air. A weak solution of detergent or soap may be used if needed. Use a neutral pH detergent (pH=7). Developed for French patisseries and a favorite of professional kitchens, Silpat's innovative baking mats create the ultimate nonstick surface. Now, the company has made a mat to help you prep pastries. Lightweight and flexible, it features a specially formulated back that stabilizes it during use.
