To prepare the metal surface to be ready for re-plating. 

Non-Electricity required.

Some gold plating hardware is partially faded. Therefore, if it is replating over the uneven color of the original hardware then the result will show the uneven color and uneven layer as well. Hence, the TK.Plating Remover will clean the remaining gold-plating and make it even in silver color before turning it into delicate gold again.
