In the past 24 months, or so, I have personally used every gram/oz of the following pre-sprays:
1. 440lbs of KleenRite’s High PH
2. 360 lbs of KleenRite’s PCX (emulsifier)
3. 400 lbs of Proschoice Extreme Clean (pre spray/ emulsifier)
4. 200 lbs of Proschoice Pro-Zyme,
5. 6 lbs of Chemeister Grease Eraser
6. 2 case
Matrix Grand Slam (mint)
7. 5 case Bridgepoint CitriSolve (booster/solvent)
8. 1 case of Proschoice FireWater (booster)
9. 2 case of Proschoice Dirt Chaser X-2
10. 2 case
Prochem Citrus Pro – (Currently, my favorite booster/solvent)
11. 90 lbs of Dynachem PowerMAXX (currently on order)
And a dozens other samples I can’t recall at the moment.
Right now I’m on an Enzyme trip. I really like Pro-Zyme but Dynachem is having a special this month and 45 lbs of PowerMAXX (w/ Enzyme and Delimonine) is only $89 + shipping. Screaming deal! If I like it and the price doesn’t go crazy, I may stick with it indefinitely.
I wish I could tell you which is best for your friend, but right now I’m still trying to figure out which is best for me.
Good luck
Ps. I’ve never heard of CarpetCop. Where can I get some?
Thanks!
