I did a residential job, over the weekend, and found that these stains wouldn't budge - the client was informed of the possible issue in advance. see attached photo. looks like rust, but it's runoff stains right out of the ground.
this entire neighbor hood has these stains and it would be awesome to find something that will remove them... this particular client will let me use them as a test subject and if I find something that works, i could try to sell my services to the entire hood.
I've heard about special acid washes and bleaches for concrete. any suggestions.
equipment used:
4000psi / 4 gallon minute
cold water
basic concrete concentrate from HD (wanted to give it a shot)
I was going to try some professional cleaners, that I have, but didn't see the point after trying the turbo on it and it didn't even budge.
