Cleaning a concrete floor maintains appearance and hygiene: It is vital to the continued performance of the finish. Dirt and grit must be removed so they don’t become abrasives that compromise the stain protection layer.
An Alkaline cleaner with a pH around 10 -11 should not damage your floor. If you choose a very alkaline cleaner, it should be diluted down. A citrus cleaner at very low concentrations can be used.
