An auto repair shop had a pro pressure washer with the trailer and hot tank and all that wash his lot years ago but he wasn’t that impressed. They also had a surface cleaner too. That’s what I had planned on using. Anyway, he has a 55 gallon drum of this degreaser called astro chem and said I could use it. I have a 4pm unit and an xjet to downstream it. The lot is about 7000 sq ft. I clean their windows so I’d like to give them a deal, plus they’re letting me use their chem and I’ve never dowstreamed a lot before. I’ve downstreamed houses so it shouldn’t be much different.
I’m seeking any advice possible. What is a reasonable price for a 7000sqft lot downstreaming their chemical? I was thinking around $500. Has anyone used astro chem, or at least heard about it? Thankfully it has recommended proportions on it.
Unfortunately OSHA wants you to reclaim any water chemical or not oil or not when pressure washing. I never have because it’s a pain to say the least. I’ve seen people put up barriers around and shopvac it or have an expensive zamboni type thing do the surface. And the fact I do a lot of my commercial at night unless the OSHA man or an environmental freak comes around then, you’re ok. Not too many people actually reclaim.
As far as chem treating the surface, just spray it on, and go. I would spray the whole thing first because dwell time makes the difference. Envirospecs surface cleaner soap works well and bleach never hurts in the mixture. But maybe this guys stuff works too, who knows.
Great advice! I should’ve gone heavier since it was their chemical. I gave it a good hour or two of dwell time too but it didn’t seem to do much. I’m now trying to finish up with the ww classic surface cleaner. Thankfully I made sure they knew the quote of $500 was just for applying the degreaser. They are prepared to pay more.
Another question I have, how long can you let a degreaser dwell? Would overnight be ok? Thanks!
You are full of yourself and something else. Do you reclaim all of your water? I don’t think you clearly understand the regulation. They want you to reclaim all of your water all of the time. I perfectly understand good business practices. Keep that for yourself. There is a bit of unrealistic regulations. If I or anyone else charged accordingly for their time, effort and equipment to keep up with the regulations- shit would not get cleaned. Because the cost would be through the roof. Understand what you are replying to before you do.
Understandable, Thank you for clarifying. I have no desire to do that either. I know my cities’ drainage well and make sure nothing harmful goes into a drain that goes straight to a waterway. It all goes to water treatment plant.
