My favorite is ammonia, but that's for actual algae.
It will turn the algae to much and you can hose if
If it's really moss that can be scraped off (which has
some height and a root system) then it's easier just
to scrape it off.
| 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 ?
