Hi All,

I noticed this arvo that my neighbours side drain was full of
something that on closer inspection was coffee grounds (it looked more
like a swamp though) !

In 30 years of demonstrating & selling pressure washers to industry, two
things stand out as being the most difficult to clean off. One is hop
resin, the other is coffee.

You would assume it would be water soluble, but dried coffee residue on
processing machinery is a real PITA to shift.
