Cleaning audio components with 90% isopropyl alcohol

Contact Cleaner AND Lubricant combo is best for moving parts. F type for plastic parts. IF there are thin felt or foam light blocking parts within, Audio Classics recommends NOT cleaning their innards UNLESS you know that part is problematic.

alcohol does leave a residue, I blow dry parts I clean with a small compressor in my shop.

don’t forget to have some liquid bearing in the shop

wear gloves if you use Goof Off or anything like this, I messed up my fingers permanently cleaning a large tape deck with years of tobacco residue with no gloves
