How to clean Potassium Hydroxide (KOH)?

[TheNextTesla]

I've extracted some potassium hydroxide from wood ash, and I've filtered it a couple of times. I was wondering if ether would work as a cleaning agent for the crystals. Someone recommended that I should use anhydrous ammonia, but I don't really want to mess with that yet. Any other suggestions would be nice. Thanks in advance! Also, the current solution is a bit yellowish, and I assume that's from the presence of other salts from the wood ash.

If the particles of wood ash are large enough to settle down in a while, then sedimentation may be useful.

KOH is soluble in diethylether why dont you just try it? Do a small sample and if it works it works

Thanks, I'll try it soon.

The solution isn't discolored because of sediment. I think it may be because of some kind of dissolved salt or carbide.
