Marble polishes like "Tenax" are standard wax polishes used by stone
masons for decades. They contain waxes like carnauba wax and
solvents, usually hydrocarbons or trichlorethylene. You can not do
much wrong with such a treatment, but the protective effect for
outdoor marble is low. The treatment has to be repeated every year.
