Alternatives to long-established heavy cleaning agents
Apparently bleach also kills moss effectively, as do washing-up liquid and hydrated lime (although I don't know whether it's appropriate to use the latter on a glass or polycarbonate roof): https://homeguides.sfgate.com/home-remedy-kill-moss-pavement-quickly-60318.html?fbclid=IwAR03E-7I5stxo9CH-VfEJwv19UFoEtOLch9tTHNuCrh4CGh5lLAksWptdRg
The RHS mentions Just Green's Glasshouse Cleaner but I can only find them selling via Amazon.
What would other people use instead?
