Abstract
This disclosure relates to a process for the removal of mineral deposits, water stains, rust, algae and other marine residue from hard surfaces, both porous and nonporous, such as ceramics, acrylics, fiberglass, plastics, marble, stainless steel, glass, aluminum, steel and other ferrous and non ferrous metals. Cleaning is effected by applying to said surfaces a viscous or gelled fluid composition containing a mineral-dissolving acid, a lubricant such as glycerin or mineral oil, and a thickening agent such as gelatin or silicon dioxide or mixtures thereof. Optional ingredients may also be present.
Claims18

- 15 to 30% by weight of a lubricant;
- 10 to 16% of a gelling agent selected from the group consisting of gelatin, colloidal silicon dioxide and mixtures thereof;
- and 35 to 60% by weight of water.
A viscous fluid composition for cleaning hard surfaces comprising 12 to 25% by weight of hydrochloric acid, 15 to 30% by weight of glycerin;
- 10 to 16% by weight of a gelling agent selected from the group consisting of gelatin, colloidal silicon dioxide and mixtures thereof;
- 2 to 6% by weight of a deflocculant;
- and 35 to 60% by weight of water.
