Any ideas as to the best way to clean rough (non-polished/honed) travertine? Stopped sealing it a couple of years ago-- no point, really, as it's in the kitchen and we wanted a weathered/worn look, and I don't think it did much anyway-- but we need a below-the-surface clean. Dirt has collected in the natural pockmarked surface and no mopping will lift it out of the tiny holes. Is there a preferred solution that will lift it out? Maybe use a steam cleaner? Wet vac after some sort of hand-brushing? Are there people who do this? Any help would be appreciated.
Good luck, Consonant Man. It is damned near impossible. I used to maintain open cell travertine floors at 9 West 57th Street and I never did find a good way to do it. I tried steam cleaning with only marginal results. I had porters use Q-tips, again only with marginal results. I even tried filling in the open cells but never could find the right akimi-stone mix to match the more weathered stone around it.
Wish I could give you a good answer, and perhaps someone out there has one, but I will wish you the best of luck.
Thanks. I think this may be a real bear. Not sure about the vinegar as it may be too acidic for the surface, or ineffective if watered down. Trick is to find some solvent that will lift the dirt out of the tiny holes (or a brush fine and firm enough to get in them), but I fear that may be nigh impossible.
I would give a carpet cleaner with an upholstery attachment a shot. My machine has a rotating brush on the attachment, and it works miracles on the tile near our back door (when I actually use it....usually the tile just looks terrible, even if I mop it daily.)
Water, fine plastic brush (wire etched a little), elbow grease, wet vac, then steam cleaner. Stone by stone. Works somewhat. Major PIA. Thought about renting a carpet cleaner but HD rental guys said it wouldn't get past the surface. Sigh.
