So I picked up another 1391401 at the thrift shop today (pics coming later) but I want to de-scunge it.
I removed all the keys (leaving ~105 silly little holes sticking springs out to mock me), and cleaned out the casing and "base" nicely, but now I've got 101 keys, some of which have dirt impacted.
I threw them all in a bag, and filled the back with hot water and soap. Some help. Rinsed and added some 70% alcohol-- no major help. What next? Is there any way I can wash them in bulk rather than spending three nights cleaning individually?
