How to clean the lime block on the external wall?

If the external wall brick of the building is seriously polluted, it is recommended to use cleaning agent. There is a thin-layer cleaning agent called Kline Concrete, which is used to thoroughly clean ceramic tiles (glazed tiles, whole-body tiles, vitrified tiles, polished tiles, decorative tiles, clay products and ash from natural stone villages) in one step.

Main ingredients: anaerobic acid, organic weak acid, RN+ acid promoter, surface protective agent.

Cleaning principle:

(1) Weak acid molecules of anaerobic acid and organic weak acid are activated by acid promoter, which makes them have strong cleaning effect at room temperature;

(2) The rich and delicate foam produced in the cleaning process can make the scale layer loose and fall off, increase the contact surface between the cleaning agent and the scale layer, and accelerate the cleaning speed;

(3)RN+ acid coagulant has strong permeability, wettability and curl. Its molecules penetrate between the polluted surface and the dirt, so that the dirt is separated from the surface. Wettability ensures that the decomposed dirt will not solidify again for washing in a short time.
