Question

I need to find an inexpensive way to remove urine stains under the urinals


Answer

Nothing mentioned below should be expensive. In fact, you probably have it on hand.
1. Strip the damaged area with a build-up removal pad and strong stripper. Squeegee and observe the results. If the urine damaged area is close to matching the undamaged area, apply a heavy mop rinse. The appearance and color match you observe will be the same as after applying four coats of finish.
2. If still stained, apply Comet with bleach, and scrub with a strip pad or carefully use a 100 mesh sanding screen (placed under the strip pad). This solution MUST remain wet at all times or the floor will be damaged. Squeegee, rinse and observe. Do not mix chemicals or combine the two steps. All chemical residues must be removed completely before going to the next step. Also, rinse strip pads between steps. If the floor is porous, such as terrazzo the stains may have penetrated deeply and may not be correctable.
A product producing phenomenal results on carpet is CTI Urine Stain Remover. It is very high in hydrogen peroxide. I haven’t tried it on hard surfaces, but on carpet it is unmatched. The directions indicate it can take 3-4 hours for the stain to “bleach out”.
You may need more frequent cleaning or to install protective mats under the urinals to prevent future problem or cover uncorrectable damage.
