Watch Hairspring Cleaner. Also the BEST Movement Final Rinse Solution.

This product is THE BEST Hairspring cleaner on the market, bottled and made here in The USA.

Will NOT harm shellac. Especially made for sticky hairsprings, but you will notice using it as a 3rd rinse or final rinse that it produces the best, cleanest, and contaminant free movement ready for reassembly. Provides the cleanest hole and cap jewels possible. It properly cleans ECM circuits and coils in quartz movements.

Dries instantly with warm air. For use as a final rinse on watch plates, train wheels, and escapement parts. It leaves a completely clean, oil free, solution free, surface on ALL parts of the watch movement after proper cleaning and rinsing solutions have been used. You can place the solution in a sealable jar that fits your cleaning basket diameter, which allows all parts in that basket to be immersed. In my Watchmaster Cleaning Machine I have a 3rd jar for a 3 minute cycle. It is shipped in a light colored amber bottle to prevent evaporation in your shop. I recommend light warm air from a hair dryer or L&R dryer which blows warm air slowly. 60ml bottle. My cost provides the amber bottles, packaging, shipping label, and supplies. Hexane solution.
