Review (5/5): Cures sticking typewriter keys
I am not a professional typewriter repair person. But I have cleaned more than my share of old typewriters with sticking keys for friends, relatives, and myself. With Liquid Bearings, it is a one-step process that frees a single stuck key at a time. Simply activate the problem key and use Liquid Bearings to clean and lubricate the metal-to-metal friction point. This particular Liquid Bearings has two sets of blunt syringe needles to help direct the liquid to the trouble spot. If you service only the key that is sticking, this bottle will last a long time.
