Damage from cleaning products almost never looks like damage on the day. It looks fine, and then eleven months later a floor has gone cloudy and nobody can point at the moment it happened.
Vinegar on natural stone
Marble, limestone and travertine are calcium carbonate. Acid dissolves them. Each wipe etches a little, the polish goes, and it does not come back without refinishing.
Oil soaps on polyurethane hardwood
They leave a film that builds. The floor looks conditioned for a week and then starts holding every footprint, and worse, refinishing will not bond over the residue later.
Bleach on grout
It whitens the surface and degrades the binder underneath. Grout that has been bleached repeatedly goes chalky and starts shedding.
Glass cleaner on coated screens
Ammonia strips anti-glare coatings. There is no repair; the panel is simply worse from then on.
Magic-eraser foam on satin paint
It is a fine abrasive. It removes the mark and a thin layer of the sheen with it, leaving a permanently duller patch that is most visible in exactly the light you noticed the mark in.
