Hi there. Longtime lurker. A long time ago in my 20s I cleaned carpets with Sears. I was just the helper, vacuuming, pre-spraying...wasn't let anywhere near the wand or upholstery, hehe. I am looking for a sideline now and think VLM methods are interesting. I like the lower relative environmental impact. Here to learn. Please forgive stupid questions (and yes, I know how to search forums, hehe).
