Abstract
An aqueous liquid composition containing glycerin and polyethylene glycol with a molecular weight in the range of about 400 to about 1000, and, optionally, additional surfactant, is an excellent liquid auxiliary for wet sanding and produces a sanding mud that can easily be removed by washing with water, even after drying.

- (A) from about 1.0 to about 50% of dissolved polyol molecules selected from the group consisting of molecules that include from 2-6 carbon atoms and at least two-thirds as many hydroxyl groups as carbon atoms;
- and
- (B) from about 0.5 to about 40% of dissolved hydroxy terminated polyoxyethylene having a weight average molecular weight in the range from about 200 to about 4000;
- and, optionally,
- (C) from about 0.01 to about 5% total of surfactant not within the scope of components (A) and (B).
