- Never let the granite pot or pan you bought from the tube come into contact with cold water to cool the food quickly! Sudden temperature changes may damage its coating. - Granite pans and pots are hand washed, never put them in the dishwasher. The salt in dishwashing tablets damages their non-stick properties. - Do not use steel wire or sponge backed hard surfaces while washing. This process will cause your pan to lose its non-stick feature. - Do not use wooden or steel spoons. Use only heat-resistant silicone spoons for granite pots and pans.
