Dave came to my condo in Scottsdale today, for the third time. You see, I have a puppy. Well, she's 1 year old now and I WAITED for a bit for his usual expertise. We had puppy accidents all over ... valuable area rugs but what was REALLY bad was the ink stain, actually STAINS, on the upholstered couch. I was sure he could do something. But what happened was magical. All stains gone. And he would not quit until it was the best he could do. Still, he was not happy because one small microscopic spot would not relent. Alas, no problem. These guys are the best. Happy to recommend them for all your deep cleaning needs.
