Can I ask the peeps on Tea? a question about cleaning patio slabs?
When I have the energy to do so, and it is not too wet, or too hot, I am planning to clean the patio slabs. They are what is called "Riven" I think. I know that a stiff yard brush is called for, but what about any cleaning solution? Would washing up liquid diluted in warm water do the trick? I do not want to use any strong chemicals, for three reasons. They harm the environment, and until it is dry the cats might get the chemicals on their paws. Also I do not like storing strong chemicals or disposing of the unused stuff. I do not think it is dirty from traffic fumes etc. I think it is when the clumps of moss get washed off the roof by heavy rain. Then the moss dries out and crumbles to black dust. Today I have swept up the moss that landed on the patio over the weekend.
