How do I get paint off of cement and untreated wood?

My mom spilled a gallon of white paint on the concrete when we were painting my garage. The paint splattered onto cement pavers and the untreated wooden fence nearby. I tried Goof Off. Luckily I sprayed most away with water. But some penetrated deep, and I can't get it off. Does anyone have any suggestions? Wood sanding it work?How do I get paint off of cement and untreated wood?
the best would be to rent a power washer





I spilled a gallon of white paint on my sidewalk and in the street and the power washer took it all off. Best thing is that its just high-powered water so no dangerous chemicals.





It could work on wood too, but be careful! It can easily gouge or dent the wood is you aren't careful.How do I get paint off of cement and untreated wood?
I was going to suggest sanding it off, but it sounds like a lot of paint to sand. It would probably cause damage to sand that much off. Try paint thinner. Actually, your best best is to go to a home improvement store like Lowes or Home Depot and ask their opinion.





Good luck!
