I don't know what that restaurant guy is talking about. Chemton's chemicals are amazing in strength and price. I own several food service related business' and I use their stuff at all locations. Hands down the worst stuff out there is this brand called Golden Shield. That guy is such a joke. Zep and Ecolab have decent products but they are too expensive. First Ayd was ok but they keep pushing 55 gallon barrels of their stuff. Who has space for that? The best part about the Chemton guys is when I call them they are show up almost immediately. That comes in handy when health inspectors are sniffing around. Hands down Chemton rocks, and all their soap is Made in the USA!
