Cleaning a concrete floor does more than simply maintaining 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. Lythic Cleaner goes beyond cleansing; it adds silica to the surface as it cleans. Reactive colloidal silica bonds to concrete, so every cleaning improves resistance to abrasion and liquid penetration. It is chemically matched to Lythic's stain protection products for complete compatibility. Sold as a concentrate, mild but effective, ideally suited for everyday use, it is the best investment you can make in maintaining a concrete floor finish.
