The polishing solution comprises pH regulator, soluble oxalate, lubricant, fluorosilicate, nano titanium dioxide, nano silicon dioxide, coupling agent, palm wax emulsion and / or paraffin wax emulsion and water. The polishing liquid of the present invention is applied to the surface of marble or wood-based panels. Under a series of physical and chemical actions, a thick layer of dense glass-like bright substance can be formed on the surface. This glass-like bright substance is hard and has good wear resistance and weather resistance. The surface of the floor forms a bright mirror effect of "a puddle of water", which is easy to repair after the surface is scratched. When polishing the surface of marble or wood-based panels, just pour the polishing solution on the marble or wood-based panels and throw it away with a polishing pad. There is no need to use polishing steel wool, which improves production efficiency, saves costs, and improves polishing brightness.
