When cleaning luxury vinyl plank flooring, you should strictly avoid using abrasive scouring powders, steel wool, harsh chemical solvents, ammonia-based cleaners, and traditional wax-based polishes or steam mops. Steam mops force high-temperature moisture into the seams, which can dissolve adhesives and warp the core boards, while harsh chemical cleaners strip away the factory protective wear layer, leaving the surface dull, sticky, and susceptible to permanent scratching and staining.
