I love the whole cleaning system for many reasons but my chem draw was messed up so I couldn't fully gauge the rinse now I am 100% it is the difference maker for sure
I have been using End Zone by Bridgepoint. I get a lot of compliments on the carpet feeling soft. I don't know the chemistry of why that is. But it is working.
End zone is a little under neutral, I ve used it and it does seem to leave threads a bit softer than other. usually has to do with lower pH of the threads. Or at least thats what Ive been told. Any Interlink guys want to addd?
