Go buy you a pressure gauge with the right fittings. all the distributors have and I believe Northern tool has too. Put at end of your hose where you plug in surface cleaner. Adjust your pressure either changing the tips or adjusting throttle on machine, usually about 80% of full throttle to get your pressure under 2000psi, say around 1800. Go back over concrete with circular motion. What you’re doing is blending it in. Not going to be perfect but will be less obvious. Everytime you wash it in the future it will get less and less obvious. You can use the F9 method or even other acids, but they all work by taking some of the surface off… Just time and normal wear, tear, and more cleanings will do the same. Since it’s on the side, I wouldn’t worry too much about it, and now you know.

Thank you Racer,
I was hoping you would stop by, lots of respect. I will certainly try the circular pattern technique to blend it in some.
I read about people using muriatic Acid and F9 to sort of blend It in… like you said though, may be better to let time blend it in for me. I’m not confident in my ability with those substances just yet. I think I run the risk of exacerbating the situation.
I’ll play it safe for now and chug a long. Thanks for your help! The gauge is ordered and the tips are going to get checked on today.

I don’t SC any concrete 2 years or newer. Ball valve about it.
