I do not think we will ever see eye to eye mike. I talk to carpet installers who say if hwe worked why is there 10-20 lbs of sand in the padding? I get hwe manufacturers telling me the carpet mills say it must be flushed or it is not clean. However science is pushing us forward every day. The best example I have is a good comparison between both methods regular upright washing machine 40 gallons of water per load, flushes the clothes, not very good agitation. New HE washing machines 5 gallons of water improved cleaners, and better agitation. I do not believe enough testing has been done on encapsulants. I just changed my god awful builders grade carpet out a month a go. It was 4 years old cleaned by hwe 4 times first 2 years every 6 months. It was cleaned the last 2 years with Encap. when I pulled up the carpet their was No Dirt in the pad or under it except a little by the edges. All the installers I have talked to told me there should have been a ton of sand. This carpet is in the living room and takes all the traffic from my 4 toddlers 5,4,3,2 you should see the amount of sand I vacuum out of the carpet. Is this a unique example no the installers I talk to I also clean for and have replaced there carpet with the same results and have stated no sand and they believe it is from the low moisture not high pressure pushing down. I do not want to start a war I value every members opinion however we are tired of being bashed everywhere because low moisture cleaners choose to go against the grain. What grain science backs this whole argument up and yet we get called hacks and every other name in the book my question is WHY?
