Solution for silicon?

I'm trying to get some old (but not very old) silicon caulk from a lightly porous surface. Some friends recommended hydrochloric acid. The silicon repels it handily. Does anyone out there know what will disolve this stuff?

Thanks in advance!

You will not dissolve the caulking. You can remove most of it by cutting, and you might remove the residue by sanding.

The only way I know to remove silicone caulk is by abrasion.
Sometimes it can be scraped off with a sharp razor blade, but there is usually some residue left that will need to be removed by abrasion of some sort,
especially if you are working with a porous surface.

I wouldn't recommend using hydrochloric acid for a couple reasons. The fumes are noxious and hazardous. Also it is so caustic it may damage the surface you are trying to restore.

Pumas stone and soapy water works good on the residue.
