Nickel Plating Salts provides a base solution to produce a basic nickel deposit. Whilst some online sources will direct you to a concoction of white vinegar and nickel acetate, this product is based upon the same chemistry industrial nickel plating is operated with. This product contains no plating additives and will produce a natural nickel deposit which can be polished if required or left in its natural state. Each 500g pack can be diluted to make 1.4 litres of plating solution.
