Pressure washer.

Do you have the Karcher patio cleaner attachment Ron? I found that it prevents me getting covered in moss splutters from head to toe

I do!
I never used it on my old Kew as it made the system hunt

Tomorrows tasks!

I got banned from using it on the drive as it made the drive look "too new"

Garden patios are fine though.

The moss on my north facing drive had to be removed somehow or other!

After a strong Domestos solution killed the growth- it all went brown - I used a Ryobi electric brush, a stiff yard brush and my old Kew pressure washer but to no avail.

The swirling pressure washer lance on the Kaecher has done the trick and seems to have lifted the fibrous roots.
