I've been thinking about this for a while, and if I put this all together in one post, it will be a novel, not a post, and will likely pique the ire of one of my friends from Alabama. So, to start with, I'd like some feedback from our friends who have been cleaning carpet for over 30 years. There is a specific reason I am saying "over 30", based on something that happened in 1986. With that understood, what were you fellow dinosaurs using to clean carpet and its pH in 1985 and before? Please don't get into what you did different in the following years....I'll get to that later. OK, sorry this is ALREADY and epic. I'll go first: Prochem Dry Slurry pH 11 (back then) through the machine, boosted with Prochem Wide Range Industrial Cleaner pH 12. Prespray was Prochem Traffic Lane Cleaner pH 11, if I thought it was needed.
