I bought 217 ounce bottles just to give it a try mixed it, put it into my bottles and started using it, and immediately fell in love the following day I gave it to one of my other crewmembers, and he absolutely loved it and on the third day, I pass it to my third employee, and she absolutely loved it I noticed I’m using half the amount like I normally would with my other product and the job is done better. The windows look absolutely brand new I’m 1000% satisfied. Can’t wait to get more. I’m halfway through my first bottle.
