I have stubborn oil stains that are 2 years old. What can I use to remove them from my driveway?
I want to remodel the garage into an extra bedroom. I think we'll cover the concrete with laminate, but until we get the money for that, I want to get out the oil stains. There all kinds of detergents including TSP, but I was told there's a motorized deep cleaner that you can rent for the job. Do you know about them?
