Our driveway is painted. The paint is peeling and ugly. I have tried power washers without any success. Can anyone recommend a product to remove the paint and stain from the concrete?

If it is already peeling, a high pressure washer water blast should take it off. But if you use it you should try a small area first to see if it causes damage to the concrete.

There is a tool you can rent from Home Depot that will remove paint. It's a sander/wire brush like thing.
