Removal by electrochemical method

The electrochemical method of rust removal is applicable for self-realization. With its help, you can solve 2 tasks at once: get rid of corrosion and prevent its reoccurrence.

This method is suitable for cleaning removable and cast parts. In the first case, it is unscrewed from the car and completely immersed in the solution. In the second case, the corroded areas are treated with batteries, "burning" the damaged surface with them.

To implement this method you will need:

  • energy source, such as a battery,
  • water,
  • a piece of stainless steel and wire.

The part that needs cleaning is connected to the "minus" of the battery, and the stainless steel - to the "plus". The start of the reaction will be indicated by active bubbling of water (electrolyte). Read about how to remove rust using a battery. here, about the electrolysis method - here.

How to clean it mechanically?

Mechanical cleaning involves removing rust using any tools or abrasives. Implementation method:

  1. foto21987-5Remove loose metal with sandpaper. Cleaning is carried out both manually and with the help of a power tool, for example, a grinder.
