Yep, it's pretty amazing stuff. Works a lot better than most of the other cleaners I'v tried. We get it by the gallon when it's on sale, and keep some full-strength in a spray bottle in the garage. It normally gets used for tires, cleaning smeary stuff off windshields, degreasing engines, black marks on vinyl floors, etc. It also works great on our vinyl siding to remove all the bug crap. There's 2-1/2 gallons in stock right now
The one thing it didn't work miracles on was the A/C coil in my truck. There was a smell coming from the A/C ducts in my 2000 Chevy, so I assumed there were "crobies" growing in the evaporator / pan of the unit. I removed the rubber elbow from the drain on the firewall, and connected a 3' piece of hose to the condensate outlet. I stuck a funnel in the hose, and filled the A/C with a strong mix of cleaner till it dripped insde the truck. After it stood for about 5 minutes, I hooked the shop vac to the hose and pulled the liquid out. I filled and flushed several times with clear water to get it rinsed thoroughly. A week or two later, the odor returned. I said something to one of our service guys at work, and he gave me a jug of coil cleaner and I repeated the process. That was early this Spring, and it's still OK....................chim
