Hello,



Live outside of Boston.



Driveway (Asphalt) is heavily covered with Green Moss

(or is it Algae, or...) which is very hard to remove.



Scraping (just too hard, and too much of) does remove it, but

surprisingly a concentrated bath of Chlorox doesn't seem to kill it.



Might someone suggest a Commercial product that I can spray on it, that

really works, to truly kill this stuff off, without poisoning the whole

neighborhood ?



Thanks,

Bob



Did you try powerwashing it? That has always taken off any algae that
I've encountred.
