hi guys I was wondering about washing asphalt… pressure was or softwash…if softwash what chemical…if pressure wash what pressure…thx billy


Did you ever get an answer your question? If so, care to share the answer. I am trying to find out the same thing, too.


No One answered. sorry. good luck

My question would be…what is the desired effect you’re looking for? How old is the asphalt? We’ve done post construction clean up on new asphalt parking lots. Ball valve wash downs.

High pressure and hot water will damage an asphalt driveway. I learned that removing some overspray from a Wagner sprayer.

Be careful.
