Choosing the right Spa Plating polishing/cleaning compound for your job

A quick reference table for hand polishing and cleaning metal for electroplating

We’ve put together a quick reference guide to help you choose the right cleaning and polishing compound for every stage of the brush plating process. Amongst all of these compounds, MPU will be the one you use most often. It is the ultimate all-in-one cleaning and activating compound, as you can use it on most surfaces in preparation for plating. If the surface of your work is very recessed, or if it is very large, we recommend cleaning and activating with ActiClean.
