Get some white vinegar in a cup/mug - put in the microwave until it starts to boil.
Remove from microwave and drop the jets in - leave for a few minutes.
Then remove and try clearing the jet with the tool above..
Vinegar is an acid that will remove metal surfaces and alter dimensions. This is why they make carb cleaners that dissolves deposits and leave the parent metal unaltered.
