I have always read about downstreaming and upstreaming and such,
but I recently saw a contractor at a gas station and I just watched them for a while and what they did was they

1. wet the concrete
2. went over it with some sort of chemical dust using a fertilizer dust droping machine(I dont know what its called but its like a cart with a hole on the buttom and a spinner throwing the dry chemical out of the bottom)
3. went over it with wands just kind of rinsing

they got in and out in under an hour it was just the front walkways and the front 10 parking spaces

anyways Ive never heard of this wonder if any of yall have, and if theres a name for this method
 
Never herd of it but it sounds like they didn't know what they were doing. Or they know something I don't. lol

You should go the next day and do a demo with your surface cleaner and show the owner the difference.
 
I was thinking they just didn't know what they were doing, but then again I don't either except for what I learn on these forums

I have already been in contact with that gas station before a while back and found out it was corporately owned and I was referred to their regional managers office and was told to submit my information and a bid but I don't even have insurance yet!
 
Since they rinsed it away it wouldn't of been an absorbant method like say Host carpet granules that you lay out, scrub in, then vacuum up.
I have seen people broadcasting dry degreaser out though on really bad areas and scrubbing it in. I've actually done it myself on ocassion. If right product it just disolves real quik making for good concentration wherever it was wet enough to actually disolve it. Add a little more water on parts that don't. Saves time and hassle of making a whole batch or having to reapply cause product wasn't strong enough at dilution. If done just right the process might save both time and money. I do it on straight grease or oil and on entry ways on ocassion. Back in the day when I was involved in some oil refinery janitorial accounts we just used what they had in way of steam powder on the big gas pads the trucks filled up at. Don't don't know the brand but it was just caustic that turned green when ya laid it.
