What Is Liquid Tin

The 421 Liquid Tin is a clear immersion tin solution designed to coat copper traces and solder deposits with a thick coating layer of tin. The deposited tin is readily solderable and it extends the work life of circuits by protecting it from corrosion.

It so happens that tin metal will dissolve in non-oxidizing acids, while copper metal doesn’t. So just immerse the object in hydrochloric acid (aka muriatic acid or spirits of salt) and the tin coating will be dissolved away.
