What do you think about me changing up my solutions that I use from Powdered Formula 90 as my rinsing agent and some cheap prespray to going with Flex and Liquid High Heat by Chemspec. The Flex is a high PH while the Liquid High Heat is a 4.7 to 5.5ph. I want to use this on all residential carpet. In the month of June I will be offering free Teflon as I know I will be stripping it away with the Flex. thoughts?
