ABSTRACT:
A cleaning and polishing composition contains mineral spirits, a first abrasive component of particles having a median size in a range of 1-4 microns, a second abrasive component of particles having a median size in a range of 15-30 microns and a fatty acid. The composition is a free flowing liquid having the viscosity of mineral spirits and has the ability to provide a long lasting finish. After cleaning and polishing an aluminum surface and after several weeks of rough use, the surface may be washed and looks like a newly polished surface. A preferred composition is 85-90% mineral spirits, balance stearic acid and aluminum oxide. The median particle size of the abrasive is less than about six microns and a sizeable fraction is below one micron.
