Has anyone come across, or even tried a patio cleaner called Hero? It
comes in a sprayer and cost me, I think, £3.99. It says just spray it
on and leave to dry. Hey presto, cleaned slabs.
No way.
It is quite useless. I've tried it on 2 slabs and challenge anyone
to tell which ones they are. One has had 2 applications, the other 3.
I'll be on the money-back trail next week.

I've not read the small print. A friend read out the instructions, as
my eyes don't do small print easily.
