If your pressure washing business cleans driveways, you will more than likely encounter oil stains that will need to be cleaned. The oil stains usually originate from someone parking a car on your customer’s driveway that has an oil leak.

The customer will expect that you will be able to clean the oil off for them.

It is a good idea that you tell your customer that you can't make any guarantees as to how much of the oil you'll be able to get off, because removing oil can be difficult.

I've used two types of oil remover, Thompsons Oil and Drive Cleaner, and Gunk Driveway Cleaner. The Thompsons one was pretty much useless. The one from Gunk gave me better results. There are a good number of different products on the market that you can try, so you just have to decide for yourself which is the best.

The two oil removers I used worked like this: you pour some of the chemical onto the stain, rub it in with a wire brush, leave for a set amount of time, maybe 15-20 minutes, then wash it off with water to hopefully reveal an oil-stain-free driveway.

It will have instructions on how to use your particular brand of oil remover on the back of the bottle.

Note: For tarmac you usually leave the chemical on for a shorter time than you would when removing oil from block pavers.
