I've used Steam Clean Express for many years and it has always been prompt and efficient, and it always leaves with no mess. They are in, they are out, and they are done--and it's wonderful. The technician had come into quite a mess and there were several spots that needed direct attention. I wasn't sure if it was paint or blood or what, but he pre-sprayed the area and then left it for a couple of minutes while he went out and prepped the truck. The stain turned out to be paint, and now it's just a very, very, very little stain left there--and there was absolutely nothing he could do about it. The majority of it is gone and that absolutely makes me happy. I will use them for as long as they'll be around.
