FDA grade silicone is highly resistant to staining. In order to avoid temporary discoloration, wash immediately after use. To clean, simply rinse with warm soapy water. You can also place in the top rack of the dishwasher, just make sure it isn't too close to the heating element. If you do notice staining, continue using and washing for a few days. Typically the discoloration completely disappears on its own. Please note, fading may occur if silicone is left in direct sunlight over an extended period of time.
Pro Tip: We recommend putting the placemat back on the tray while wet then letting it air dry before the next meal. This trick gives it a little extra stick!
