Okay,

I've got a concrete drive which gets marked badly at this time of year
by
starlings who are eating berries and/or blackcurrants and leaving purple
marks everywhere.

I have tried scrubbing the concrete which brings up the original colour
of
the concrete but the bird mess mark remains.

Any advice on what household cleaner or chemical would help remove
these
stains ?

Thanks.

Mike.

Strong solution household bleach leave for 30m minutes then hose
f ---
note this also an effective weed & mosskiller so use with care near plants

Does it kill the weeds by being absorbed into the leaves, or via the roots?
Would it be bad for plants other than weeds if some of the bleach leaches
into the soil?
I have a vast amount of moss on all my garden walls, and on a number of
patches on the soil in the beds. At present the moss is winning the batle,
and I would be interested in the bleach approach if I knew that it would not
be harmful to the desired plants.
