Washing keyboards. (Score 1)

I've taken apart many of them and washed the "Cheap" contact surfaces (not getting any Water or Soap on the circuit board) with a wet rag and a tiny bit of soap then again with a clean rag. The plastic keyboard it self I have scrubbed a bit and rinsed well and let all the part dry on a Towel turning them over a few times for about 3-4 days then put them back together and they work fine.
