Anyone have a decent way to clean these switches without destroying them?
I have managed it once by opening them up completely by lifting the white clips and taking them completely apart and flushing with contact 60, wl and 61 (european deoxit, flusher and lube).
But it took me an entire morning to put it back together with pincers and a very steady hand.
The slightest misalignment bends the copper contacts inside.
I was thinking with a very fine injection needle and compressed air?
