From time to time some bird - or perhaps several - takes up
residence in a tree overhanging a concrete walkway, patio,
or driveway. Very quickly a good bit of white bird-poop
accumulates. I haven't found a good way to remove this from
concrete. The hose gets the top 50% or so, and a stiff
broom then gets maybe another 20%, but the last 30% or so
just stays and stays.

Anyone here found a good way to remove the residue after
modest hosing and brushing?

Thanks.


If that is all you have to worry about, you have no problems except you
need a hobby, or career, or volunteer job. (or all of them).
