Generally, I don't. The sun does it for me. Algae will grow only
where the sun doesn't reach. In places where the sun doesn't shine,
I use a stiff broom and sharp sand[*].

Yes, but you DON'T want Pathclear to run onto plants and ponds.

As Nick says. Pathclear is a herbicide, very good for killing weeds on
gravel paths. It wouldn't be a good idea hose it off a tarmac path onto
a garden.
