Our multi-purpose cleaner contains disodium EDTA. It can form an invisible protective layer to resist future pollution and maintain long-term cleanliness. It provides lasting freshness, removes odors, and keeps the air fresh. The usage method is very simple: Put a tablet into the sprayer, let the tablet dissolve completely, then spray the cleaning solution onto any dirty surface. Let the solution stand for a while, penetrate and decompose dirt and stains, and then wipe it clean with a towel or sponge. Moreover, the cleaning ingredients penetrate into the stains and eliminate stubborn stains. It reduces static electricity on the surface of objects, reduces dust adsorption, and maintains the cleaning effect for a long time.
