Removing Kiln Wash

Kiln wash can get stuck on items for a variety of reasons

A variety of ways to remove the kiln wash are:


Grind the kiln wash off with diamond hand pads, or small rotary tool with wet sandpaper. You can then proceed to continue to grind with successively fine grits until a polish is achieved, or you can fire polish after a thorough cleaning.


Example of scrubbing kiln wash off



You can sandblast off the kiln wash and then proceed in either of the fashions above.



You can soak small pieces in tri-sodium citrate and then if necessary scrub with a wire brush – a brass wire brush is preferable to steel one to avoid scratching the glass.

Another solution is to place small items in an ultrasonic cleaner basket with water and a little soap or proprietary cleaner. Leave for an hour or two and they should be free of the kiln wash.
