Cleaners

Cleaning the affected fastener and bearing surfaces has several complementary effects.

Firstly, you are removing a small amount of the material causing the problem.

Third benefit is size correction. Serious contamination can give a false feeling of the size of the head under the tool.

Second, you gain visibility of the material trapped between the fastener and the assembly.

The final and best reason to remove contamination is to help subsequent lubrication.
