I've battled this stuff for years after I discovered it the first time.
It seems to happen on almost all dishwashers regardless of the cycles
used, and as best as I can tell, the sludge seems to be a combination of
dishwasher detergent and grease. Once I discovered this I began a
monthly regimen of monthly scrubbing with a light grade scrubby sponge
which doesn't scratch but does break up the crud. Oddly enough, my
current dishwasher (a very inexpensive Whirlpool) does not develop this
problem at all. Having said all that, I'm not sure that this stuff is
all that dangerous givent that a large component of it is detergent and
that very hot water is always being jetted throughout the machine. I've
never seen any of this redeposit on any items being washed or in other
areas of the dishwasher.
