If we can see a slight corrosion, there are two methods for corrosion cleaning:

1. Using a set of tools fixed terminal cleaning; There are many opportunities in the market for various tools businesses.
2. Or a combination of the use of a suitable wire brush, depending on the type of terminal, and contact cleaner.

Where corrosion is severe to clear damaged terminals, clean and attracts the child and crimping and welding of the new terminal in the purified cable. Using appropriate heat shrink tubing, the region covered crimping help prevent return of corrosion.
