Grit is what actually scratches a floor
Not shoes, not tires. The sand and grit they carry in. Removing it weekly does more for the appearance of a floor over ten years than any product choice. A walk-off mat at the entry, or a three-metre matting run in a commercial space, is the single highest-value maintenance decision and costs almost nothing.
Products to avoid
Citrus-based cleaners, vinegar solutions and anything acidic slowly dull a polyaspartic topcoat and leave uneven sheen. Soap-based products build a film that looks hazy. Bleach is fine occasionally at dilution but not as a routine cleaner. If a label does not say pH-neutral, assume it is not.
Spills
Oil, brake fluid, gasoline and antifreeze wipe up without staining if dealt with reasonably promptly. A polyaspartic topcoat is chemically resistant rather than chemically immune. Battery acid and pooled solvents are the exceptions worth acting on immediately. Road salt should be rinsed off in spring rather than left through summer.
Commercial routines
An auto-scrubber with a non-aggressive pad and a neutral cleaner, on whatever frequency the traffic demands. Avoid high-speed burnishing on a coated floor. That is a polished concrete technique and it will burn a resin topcoat.
