I use wet and forget a fair bit at work on our tennis/hocky/multi use surfaces and it’s pretty good. Everything must by DRY for it to work though. Oh and not too hot, don’t use it in baking sun.
Brush the worst off with a broom, if you have a leaf blower dust it off too. Spray with W&F and pray it doesn’t rain for the next 6 hours. Then forget about it, if you look at it everyday you won’t notice that it is working, but go back a week later and you really can see the difference after a couple of weeks it looks good. If using somewhere that doesn’t see direct rain fall run a hose over it to wash the dead stuff off after a week and then again the next week and it’ll work ok.
I use it because it’s pretty low in the toxic stakes and it seems to keep things clear for longer than the harsher stuff, which at point of use cleans and kills things much better. Good if you are cleaning as a one off. But IME the mold, moss etc comes back much quicker and gets a stronger hold later.
