We've tried every carpet cleaning technique available here in San Antonio, including steam, dry, and a couple of others. We've had some very unsatisfactory experiences. Then my daughter recommended Xtreme Clean Restoration and Carpet Care, and it was the best experience we've had so far. They did a good job. They missed some old urine spots on the carpet, but I called them and they came back and cleaned it up with some magic spray bottle, so we're very happy with them.
