I've got a fair amount of mold on my driveway & walkway (especially), in the past I've used a pressure washer, but the top coat has taken a beating from the high pressure.
Last wk-end I tried a mixture of bleach (1:3 Bleach:water) and it made a moderate difference, but I'm realizing that bleach is not a sulfactant, ie it doesn't make the liquid penetrate/bubble-up/get into crevasses.
So far the grass on the sides of the walkway seems to have survived the bleach mixture (I did rinse with a LOT of water).
Has anyone used oxy-clean do to this job? Either oxy-clean alone or with bleach? Thoughts? ideas?
I googled around and found a mention of 1 cup of oxy-clean to 1 gallon of very hot water. Not sure if the grass will survive the treatment, though.
Open to suggestions!
