Neutralytes

Because most electrolytes are salt solutions, any mark or etch must be neutralized by wiping it with, or soaking it in, a neutralizing solution for a specified period of time. If the wiping operation is used, the part should be dried before wiping with the neutralizer.

If a pad saturated with neutralizer is used to wipe parts which have not been dried, soon the pad will have more electrolyte than neutralyte on it, and the corrosion problem will be aggravated instead of eliminated. Soaking in a solution especially prepared to counteract the action of the electrolyte is the other method of neutralizing. These solutions usually are diluted with water ( up to twenty parts of water) depending upon the application. Soaking time is about ten minutes. After this, the use of proper neutralizing oils will insure against corrosion. The type of oil depends upon the application.
