My church recently had our concrete floors stained and then sealed with 2 coats of urethane..I have tried cleaning and buffing with a neutral PH floor cleaner which left a film on the floor. I have a couple questions since I am in charge of caring for the floor1. How do I keep the floor clean and shiney without leaving water marks or soap film on the floor?2.How do I buff and shine the floor?3.How do I remove the scratches and scuff marks from the floor?
All I would add to Ultimate Washer's answer is that periodically it just pays to put another coat of Urethane on it. It will help fill the scratches and a good buff will make it look good as new. Obviously you can't repeat that indefinitely, but a few times at long intervals won't hurt. The one thing you want to AVOID AT ALL COSTS is letting anything RUBBER sit on it for extended periods of time. It will partically dissolve into the urethane and you'll get weird patterns on the floor.
A floor machine is the best answer to all of those issues. You see people in hospitals and stores use them. They basically have a spinning head that you can put a pad under so that the spinning motion will clean the floor. You can use regular mop water with these, and the pads come in varieties from soft, polishing pads to rough, Brillo-style pads for serious cleaning. If you don't want to invest in a floor machine, a mop and some stiff brushes are your best bet for cleaning, and an automotive buffer (with a polisher) for polishing. To save even more money, you could make an enzyme cleaner for practically nothing. These clean well and even give your floor a shine. I'll post a link to how to make these as my second source.
