I have some stains in my driveway/patio. Some rust stains for boat hitch chains, and some stubborn oil stains for a leaking 4 wheeler, and also some wood stains from when i stained the dog house. I have a 3000 psi pressure washer and concrete solution to add to the tank, but it doesnt work. Any suggestions???

There is a very similar post one thread down. I have left a reply there. I guess it is a popular question today
