Using this silicone heat - resistant mat is easy. Just place it on your countertop before using hot hair styling tools like curling irons or blow dryers. It will create a barrier between the hot tool and your counter, protecting it from heat damage. When it comes to maintenance, you can simply wash it with mild soap and water after use. Let it dry completely before storing it. As for precautions, don't expose the mat to temperatures higher than 450 degrees Fahrenheit, as it may affect its performance. Also, avoid using sharp objects on the mat to prevent any cuts or scratches.
