One Dip hairspring cleaner is a fantastic product for use in the watchmaking trade. It has the ability to remove old thick oil deposits from watch jewels which need to be chemically clean in order for the watch to function in a proper manner.

The solution is also used to clean hairsprings on watches. If any amount of oil comes in contact with a hairspring, it will cause the coils of the hairspring to stick to each other. This will cause the watch to run very fast. Some watches such as pocket watches can pick up several hours per day due to oil on the hairspring.



One Dip can be purchased from most watch material supply houses. It comes in the quart size can, which will probably be discontinued in 2006. Most companies will stock the smaller bottled version.

The following diagram shows a basic idea of how the coils of a hairspring will stick when contaminated with oil.




When the hairspring has been properly cleaned, each coil should breathe without touching any other coil of the hairspring as in the diagram below.



One Dip is also being marketed under another name which is called Dip Once. The chemical properties are the same.

This solution should be used in a well ventilated shop or working environment. It dries very fast and leaves no residue on watch parts or hairsprings.:D
