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. One of the most important stages for successful electroplating is the surface preparation stage and our MPU will be the one you use most often. It is the ultimate all-in-one cleaning and activating compound and helps you to achieve a water-break-free surface.
If the surface of your work is very recessed, or if it is very large, we recommend cleaning and activating with ActiClean.
If the surface you are plating is matt and not highly polished, the final surface will also be matt. Electroplating will not turn a matt surface shiny.
