Chem-Dry Of Colorado did a fantastic job for me and I would recommend them highly. The quality of the product they use is great; it's low fume and low odor. I had them work on a very expensive Midcentury Modern armchair and they removed a stain on wool that was really tricky. There was no odor and no residue when they were done. The work quality of the cleaning technician was also excellent. He laid out everything and made sure to protect my other things, like covering the area rug etc. He was very professional and made sure that he was doing what I wanted. He even placed the furniture in different lighting so I could look properly and he asked me what did I see, what did I notice. He was really great. I also regularly purchase their spray to give as Christmas presents!
