I still clean carpets for the Zep rep I had at my car wash. Actually, bought some stuff from him the other day-trigger sprayers.
Anyway, he told me that everything Zep has in HD is a diluted version from their industrial product line--Some with a completely adifferent name, just a weaker formulation of something from the industrial side.
They can't sell that stuff to Joe homeowner that they sell to industries like car washes, etc.
I remember changing out a drum of rim cleaner at the car wash...was in a hurry, no gloves. just moving the draw tube to the new 55 gal drum--Washed my hands after...skin was coming off in sheets, about an hour later I was sick as a dog! I learned a new respect for chemicals that day. Took about a week before my hands worked right after that. Face, arms, broke out with some kinda rash...it was NOT good.
