So I’ve used a lot of car washes and let me tell you this stuff is amazing. 1-3 oz per gallon is all you need, creates a lot of suds, It rinses clean and leaves a beautiful rich dark shine as it adds wax. I don’t buy into all the flashy advertising so actually what attracted me was the simple label And what it said it can do . I have a lot of trucks so wanted something that when rinsed leaves no residue when wiping dry and pretty universal cleaner . This stuff literally pulls the dirt off I put a little bit in a bucket with water just to wash my door jams by hand and I decided to start moving slowly to the inside of the Truck and it literally pulled the dirt out of the rag and everything I wipe with it, I wiped the hole inside of my truck down dash, seat etc and left squeaky clean and ready for dressing,like I used a steam cleaner , does not feel soapy at all it’s simply amazing stuff , it just goes to prove you don’t need a whole lot of something to make it work . Give it a try you won’t be disappointed !
