Urine in porous bathroom tiles

Hi dr. I clean bathrooms at a swim centre . The floors in the bathrooms smell a lot. The environment is hot humid and wet most of the time which doesn’t help. The tiles are porous and has built up over years. Currently I’m alternating between bathroom cleaner, ( sulphamic acid, citric acid and benzylkonium chloride) the next week I use like a domestic like cleaner ( bleach, alkaline salts and caustic sofa) . I soak then hose off.
Any suggestions would be appreciated
