Windex is fine, but you can use Sparkle or anything else. SPray, wait about 30 seconds. I use a soft tooth brush. Rinse in clean water and dry right away.

Same warning as all others. Cleaning HS chips may harm them or change the color.

I've used Amour All multi-purpose foaming with no problems.

CRC glass cleaner and label remover.

Windex.

Dollar store glass cleaner.

In case the dishwasher warning didn't get throguh. I tried it once and the chips were ruined. I ran a batch of old "cheap chips" to see what would happen.

Faded, dried out, warped. (but it didn't hurt the hot stamp?)
