I am pressure washing a log home that has been previously treated with a oil based stain. Pressure washing with bleach doesn’t remove the oil based stain. The owner bought a cleaner from Perma Chink and it isn’t getting the job done. There is a lot of graying and black mold /mildew on the logs. Some of the old stain is off leaving sun damaged wood. What do you suggest I do in this case? The customer isn,t willing to use a buddy blaster.

Thanks,

Jerry Miracle
