He actually hasn't arrived yet, but L&R had excellent credentials, responded quickly, and addressed all my questions re: residential grade fabrics versus the high end commercial that he provided as references. As a designer, I have used both commercially graded "rubs" type fabric but this was a Zimmer and Rhode (I believe is the name....) ikiat with crewel embroidery that I had (minimally) stained with a highlighter. Therefore, it needed a gentle wand for the embroidered areas, special treatment for what are probably some kind of petroleum based chemicals (that would be in markers), and general cleaning for lightly soiled use but on a fabric that has never been cleaned. He was great with a super prompt reply, answered all my questions including those about product used and any post-cleaning smell that will dissipate, or at least does with the better contractors.
I'm not a real "green" researcher simply because sometimes I have felt that I paid quite a bit through these type of services who sell cleaning services, but their product and "after smell" didn't clean the piece very well and kept a smell in the upholstered piece (past situation with carpet and couch when I had things cleaned in Arizona a year ago). So, until he actually comes and cleans, I can't give an actual review on the work, but thus far in terms of quick, accessible reply and his understanding of my concerns of commercial vs. residential, he has been very direct and helpful.
