How do I clean zero grout lines on travertine tile floor?
Q. I have a large space covered in dull travertine tile which i am planning to polish and seal. There is a zero grout which has become very dark. how can i clean the grout without damaging tile?
A. There are several alkaline grout cleaners that should do the job. Avoid any acid based cleaners since they will etch the travertine. Since you will be having the tile professionally polished, I would discuss the grout with the contractor and make sure they are aware that you want to grout cleaned also.
