I poured a drive on a spec house about a year ago. Last year the home went through the typical pollen drop season from a Red Oak tree, in the vicinity of the drive, with no problems. The oak is huge but the pollen typically drops straight down to the grass below it - never reaching the drive. Anyway, we recently had a severe hailstorm in GA. and it drove all the newly ripened pollen tassels onto the home's roof, then to the valleys, then it was forced down to the drive itself in heavy concentrated clumps. All the pollen from this huge oak was concentrated onto the drive in a 12 by 12 area.
I got it up the next morning but it was too late. It had already been wet and bled out dark brown stain. Tried pressure washing (3000psi) with a little bleach but it doesn't even faze it. Any suggestions?
Any recommendations here would be appreciated:
