F9 and oil

Complete cleaning first using EBC for the oil. I pretreated one guy's stains twice with EBC over a five day period. Worked super and a great upsell.

When done, F9 on the rust or battery acid stains.

Hey Ted. When you pre-treat, do you clean the area with oil spots first, to remove any oil that would just come off with the washer? then put down the EBC? or do you just apply EBC?
