Chemistry

Chemicals for collection care — professional products for cleaning, preserving and protecting coins, medals, badges and metal objects. This category includes solutions for silver, copper, brass, nickel and nickel silver, products for removing oxidation and patina, as well as protective coatings and preservatives.

Important: cleaning a coin is a process that can either increase or significantly reduce its collectable value. Use a product specifically designed for your metal, be sure to test it on a less valuable specimen, and never use abrasives on coins in UNC condition — natural patina is often valued more highly than a ‘clean’ surface.

Each product comes with instructions specifying the contact time and recommendations for neutralisation after treatment.
