mine was bacteria/mold, not mixed fluids, and was not completely blocked, but I took tank out which was probbaly overkill, unecessarily breaking the water-tight pump/tubing seals;On the subject of cleaning myself, do I need to take out washer bottle by removing wheel and Wing cover?
but if it is blocked could be stuff in the tubing on the way to the nozzles, for cleaning I have also inserted needle into the jet nozzle, but take care not to break needle
