Hydroxide for paint / graffiti removal?

Any one think this would work? Haven’t any pictures but customer says the drive way has some spray paint from overspray. I know worlds best graffiti removal would do good but we had a lot of caustic soda. Think we will try unless someone knows it won’t work.

Take pictures, I’d be curious to see results

What type of paint?

Not sure yet. I assume it came out of an aerosol type spray can but that doesn’t help. I will do an alcohol swab test and find out.

I do know that spirits didn’t work

Some of the paint did okay with the treatment. None of them sexy fixes by any means but did something.
