Do you think manufacturers would put sand, one of the
few common
substances that will scour glass, into a substance used for cleaning
glassware?
Sand, no, but silicon dioxide, quite possibly. (Not all silicon
dioxide is sand.) In sufficiently fine particles, it won't hurt
anything - consider that polishing agents are basically just abrasives
on a very fine scale.
Detergent, on the other hand, does not react with
oils, it works like
soap to mix with free oily substances and water.
I've heard that that's not actually true, that detergents actually
cleave fats and oils, digesting them, if you will - that that's the
difference between detergents and soaps, in fact. But that was afrom a
relatively non-authoritative source; anyone here actually know the
chemistry of detergents and how they differ from soaps?
