Abstract

A pad of absorbent, porous material such a felt or sponge is soaked in distilled water and applied to the patches of powder resulting from efflorescent salts; a direct current is then passed through an anode and an electrode buried in the pad which produces an electro-osmosis effect decomposing the salt patch.
