Chem-Dry of Marin was here recently and cleaned my carpeting and two area rugs. The area rugs came out great but the carpeting looked terrible, it was like there was no difference at all. I ended up getting on my hands and knees to scrub some spots out. I knew those stains would be difficult to get out, but I don't even think he tried. The stairs are still really dirty. As far as I could see he didn't get the verticle portion of the steps. I didn't see any improvement. I've used them before and they have done a better job in the past, but the last time they were here I had pretty much the same experience. I'll be shopping around the next time I need my carpet cleaned. The guy was pleasant and quick, but the result wasn't what I expected.
