There is still green in the grout and some we couldn't get off the brick but got about 90% off We are happy.
I used this to remove some spray paint on my car.
Goof Off FG672 Graffiti Remover took off the stains I had on my driveway that no other product I tried worked.
And in the process I noticed that it removed the oxidization of the paint on my driveway, so I did my entire driveway and it looks great.
Did not work on my exterior brick wall or the sidewalk which was the reason that I was trying to get pink spray paint off of that a former tenant left it only worked on the wood decking.
Does not work for spray paint on concrete.
With a grill brush and this stuff the spray paint that had been on our patio for over a year was gone in 30 minutes!
Maybe it’s good for a car paint but not for the plastic materials someone sprayed paint my car I tried to use it and it was fine on the car paint but when I use it my plastic side car pillars they got damaged this product took the spray paint off but also some plastic black paint with it now I have to buy pillar posts for my car in chrome color to stick on it :-/.
