YES.
I buy the inside cleaner, but some do smell....so I use 'magic-sponge', from the $2 shop....in a long pkt. Works wonders, you just have to keep a bucket close to clean the sponge, each time you use it.
Smell free too! they are the best.
Outside, I use a strong bleach straight on concrete, but the very thick one....so then just put onto the areas with a plastic watering can .
Sometimes I use a little water mixed in to do bigger areas, and use maybe 5-6 bottles.
Let it set into the concrete, and hose off 6 hrs later.(just make sure where the 'washing off go's'...
Moss on the other hand is wonderful on pots and some fences.AND! I think that is green moss in the Picture....but, some folk like it to look clean, which is ok too.
Mould is very different...anyway, in the house it turns black, and not good.Need to get rid of it quickly.
