Nothing is more frustrating than stuck on kiln wash! Here are a few methods that work to remove it.

1. Sandblasting – this is by far the easiest way.

2. Vinegar – Soaking the glass in distilled white vinegar (a mild acid) for two to three hours will often help the kiln wash come off with a minimum of scrubbing.

3. Wash Away- This is a great product that can be bought to remove kiln wash. Simply pour on glass, scrub with scouring pad, rinse.
