HP-67 - need help to remove cleaning residue

[Geoff Quickfall]

I would hold off on the liquid gold. It does contain natural oils which are also sovents especially if left on to long.

The reason some people have success is that the lacquer finish is still intact, or the family of calcs they are restoring have a robust finish. Woodstocks are notoriously less resilient to cleaning. Coconuts can withstand a lot of physical cleaning and of course the pioneers, voyagers with metal overlays withstand a lot except for sand paper!

I tried Armorall for car plastics and removed the printing on a Woodstock. Stick with soap and water or if you are afraid of diassembly a q-tip and soap and water, not oils, cleaners and etc.

The best is to diassembly, here is a 45 that was done:
