D-lysergic acid. When I used that, stuff disappeared and then suddenly re-appeared.
I'm going to do a time lapse for the eastern boys who don't know what it's like to live in an area where a fire hose on a fire is no good becaue the air is so dry it evaporates before it gets to the house
This is Chris's first summer with chems on concrete and caustic dries up in about 2 minutes. A completely soaked sidewalk can be dry as a bone in the same amount of time. Is this ok with most concrete cleaning chems?
If its a small enough area cover with plastic and let marinate. That has been the key for me removing things like mortar stains and hard water deposits. Makes all the difference, especially with a pricey chem like klenstone or something from eacochem - they work great but if they dry up before they're done, your done.
I think if you mix your soap from a powder with water, When it drys up its fine because the powder part is still there, but the solvent could evaporate. I think caustic changes the greasy dirt to something else (saponification) that can be washed off later even after its dry, of course you get it wet when you clean it.

Brandon, even hot concrete if you soak the surface good, the ox should work. Its almost an instant type reaction, spray it on and it starts to disappear. This is for irrigation type rust stain. Other metals rust sometimes Ox wont work at all
Brandon / Tony, I find during our pizza oven summers that if I'm doing flatwork during the daytime, I first cool down the concrete with a good, long water flush. Chemical's dwell longer, less waste.
I don't use oxalic or caustic's, I only use Power Stroke and Rust Away.
You should have the next Vegas RT in the middle of July or August! Demo on a car lot again and let them feel the 120 deg heat and the radiation effect of 150 deg asphalt.D-lysergic acid. When I used that, stuff disappeared and then suddenly re-appeared.

What are Power Stroke and Rust Away?

I thought you were never supposed to let caustic dry out on your surface though?
