Do you need to remove old solder?

What will dissolve lead?

Organic acids, such as acetic acid, dissolve lead in the presence of oxygen. Concentrated alkalis will dissolve lead and form plumbites.

Does solder dissolve gold?

The tin in molten solder rapidly dissolves gold. If sufficient gold is dissolved, brittle intermetallic compounds can be formed in the solder joint. Indium dissolves gold at a much slower rate than tin, and a number of indium-based alloys are available to suit different requirements.
