Clermont, FL Hi Michael, A good power washing should take it off for you. If that doesn't do it, mix in a little bit of oxygen bleach into a spray bottle and wet down the area. Wait about 25 - 30 minutes before giving it another wash. Michael Chapel Hill, NC Thank you Dan's of Central Florida,... Clermont, FL Happy to help Michael, good luck!
