I've been using SF Carpet Cleaning for most of my 30 years in SF. Whenever I strayed (eg Coit), I regretted it. I've only had excellent technicians who know their business, excellent service and the most reasonable prices in town. Mike is great. He knows the business inside and out, and comes to my rescue whenever I need him. I'm currently living in an apartment building built circa '77. I think the original rugs are still here. You'd never be able to tell. And the carpet is white! Whatever it is, Mike knows how to get it out, including those stains that magically reappear a few days after other carpet cleaners leave. And for much less than they charge. Last but not least, my carpet is dry in about an hour. It's a miracle. You just can't go wrong with these guys.
