You use it 1:4 regularly? do you this same ratio on carpets, vinyl, tires, engines ect? how well does it work as a window cleaner? also on the homedepot website it says its a multipurpose cleaner not an all purpose cleaner.
Exterior only at 1:4. Interior is 1:10.
I found an APC at smart and final for 10 bucks in a gallon size. its called Breeze. Its been great. at 1:15 is stronger than purple power at 1:12. purple power is suppose to be a degreaser which is suppose to be stronger than an APC. I'm gonna try purple power 1:1. Breeze has been great for tires, carpets, leather, vinyl, door jams, ect all at 1:15. I feel safe using it on all of those products. breeze also dose a good job of removing smells too and after doing seats and the carpet, the car smells new. I have to say breeze really does work like magic.
I was just at the dollar store and saw 32 oz bottle of apc conentrate. and it said, "as seen on TV." i dunno if thats good or bad. La's Totally Awesome All Purpose Concentrated Cleaner and Degreaser.
