Sanding and Finishing - Clear Up Confusion About Maintenance
Q: Can I use one of those steam cleaners advertised on TV on my wood floor? Everyone has seen the commercials showing a steam cleaner magically sanitizing, disinfecting, deodorizing, and cleaning a wood floor. But that doesn’t mean that wood flooring manufacturers or finish manufacturers think steam cleaners are appropriate for a wood floor; in fact, some have begun to specifically mention steam cleaners in their list of don’ts. Inspectors are also starting to come across floors that appear to have been destroyed by repeated steam cleaner use. Peeling finish, whitening finish and cloudy finish are just some of the side effects being reported by people looking at floors after steam cleaning. In general, the oft-repeated industry saying “Water and wood don’t mix” holds true. Unless the wood flooring or finish manufacturer says it’s OK, it’s safest to assume steam cleaning is a no-no on a wood floor.
Q: I read that a good wood floor cleaner is vinegar with water; is that OK? Vinegar and water used to be a typical recommendation for cleaning wood floors with a urethane type of finish. These days, however, most manufacturers recommend cleaners that are specifically formulated for wood floor finishes; in fact, vinegar is acidic, and using too much could damage the finish. People who insist on still using vinegar should use plain vinegar—not apple cider vinegar, red wine vinegar or any other type, which could leave a sticky residue on the floor.
Q: I keep hearing that I should find out which maintenance products are recommended by the finish manufacturer. But I have no idea whose finish is on our wood floors. What should I use? The vast majority of wood floors around today, whether they were finished on-site or are factory-finished, have some sort of urethane-type finish. For those finishes, a cleaner recommended by any major wood floor finish or wood floor manufacturer should be just fine. A safe bet is to stop by a local wood flooring retailer and find out what they recommend and sell for use on wood floors. Not all maintenance products that are labeled for use on wood floors are recommended by major finish and wood flooring manufacturers. (In fact, some may even void your floor’s warranty.) For one reason, see below.
