Hardware cleaning.
Before:
Here's the bath solution. (Kita agad yung dumi after 30-45mins, greenish yellow gunk.)
After:
Notes:
1) WD-40 muna, at full strength, for 30mins. Then I mixed in the lemon oil.
2) After 1 hr total, I used a toothbrush, plain green scouring pad, and 1000 grit sandpaper, in that order, to get the stubborn spots.
3) A small spoon works well to remove saddles on a tune-a-matic bridge. Also used same spoon to re-seat the saddles. Remove wire first.
4) Give everything a clean wipedown before re-assembling.
