I have tried SH on several driveways and it did not work on all of the leave stains Although, it does work on most of them.

Hmm. Maybe I just keep getting lucky and the stains aren’t that old.

I think you are right…I suspect age of stain has been the problem in my experience.

@Fatdaddy @JimLuke made a good point about how long the stains have been there. Might take repeated applications and a soft bristle brush to work it into the concrete.

Didn’t shoot strong enough. Use a 3.5-4% roof mix. The soap in the mix helps it penetrate.
