Q: I have had a travertine patio for approximately 10
years installed in sand. It has accumulated dirt from not being hosed or
washed. What products do you recommend to clean it?
A: How to go about cleaning your patio depends
on whether your travertine is filled or unfilled.
will usually have its holes filled in with colored Portland cement. Since the
fillers typically do not take a polish, they tend to give the stone a blotchy
appearance. Unfilled travertine, which exhibits holes, is widely used on walls,
floors and building exteriors.
If yours is filled, it
can be cleaned with a PH neutral cleaner. If it is really dirty, purchase a
heavy duty stone cleaner.
If your travertine is
unfilled, you can use a low pressure pressure washer, one that does not exceed
300 psi. Unfilled travertine can also be cleaned with the stone cleaners
