Ripster, I have no plans on brushing acetone on my keys any time soon. I noticed you didn't show the 99% alcohol test where the Filco didn't fare so well.
Sweat IS a solvent. Ducky thread here (now locked).
But yah, I don't recommend alchohol for cleaning Filcos. Either does the OCN Mechanical Keyboard Guide.
