How do you get a paint stain off concrete?

There is this great stuff you can buy at most hardware stores called Graffiti Off, it is used in the inner cities to remove unwanted ';artwork';. I know, one of our youth groups in my old neighborhood used it to clean some buildings to try and clean up the area a bit. It works great.How do you get a paint stain off concrete?
You might try ';Super Clean'; by Castrol. Will get oil stains out of concrete.How do you get a paint stain off concrete?
Muriatic Acid (spelling is probably wrong)





My husband would use it to clean off anything on the driveway...kills weeds in the cracks too...removes moss or alge from the pavement...pulls a layer of concrete off. makes it look like new!
Try paint thinner heavily soaked on a rag place it on the paint stain and soak the rag again then turn an empty pail over on top of the rag to keep it from drying out too much or too fast. Wait for thirty minutes or longer if you check and all the paint isn't coming up.





If that don't work then try using a product from Wal-Mart called Castrol Super Clean found in the Automotive section. Again use the same method as above and this will get the stain up. Castrol Super Clean has a mild Hydrochloric Acid base and I have known it to take a half inch of motor grease off a motor block in about an hour.
I would think paint thinner would do the trick....it works on getting glue off of under linoleum floors.
Don't know about paint on concrete.However, I removed dried om roofing tar from the driveway with gasoline. Just don't light a match !!!
try a pressure washer they usually get anything off
