I also bleached it within my regular wash. I would appreciate any support. Oh ya It has not be dried yet, so its not set contained by that way
Answers:    Try Oxy verbs. It removes stubborn stains. You just help yourself to a scoop and include it to the water.
you may want to try dish soap. apply it directly to the stain and sympathetically smoosh it around. let it sit for a few minutes after rinse or toss in the hose. it will help cut the grease from the tire.
