Patio cleaning help

Mehullakhani

Hi All

Have been given the task of cleaning the patio as best as possible before May 8th - family coming round ! :eek:

Anyways, I have purchased Nilfisk C110, and have had a good go at the patio - as below :





I am really struggling with getting all the black spots off - which I believe are lichen spots ? I think ?

Can anyone recomment a good liquid cleaner that I could use. I have tried bleach, but it didnt do a lot. I have heard lots of warnings about certain chemicals, and am not sure exactly what type of stone I have, so dont want to do any permanent damage .

Somepeople have recommended this :

Any opinions ?

Thanks

Pressure washer will be the quickest way to shift that.

give it another go with the 110 machine. if that doesnt shift it all then you need to beg/borrow/steal a bigger machine.
ie., a 150 bar machine will shift it all ok.

Cheapest MSE method.............Get a stiff scrubbing brush from the pound shop and get on your knees and scrub it.
