I am doing a big mulch job for a very upscale customer. Fortunately they are out of town for the next few days. Unfortunately the delivery truck dripped some oil or transmission fluid on their driveway. Half of the drive is brick, the other half is asphalt. I have a Crapsman powerwasher but I don't know if that is the answer. Should I use something else or some type of cleaner for the power washer. I need this done Friday morning so any quick responses will be appreciated.
