Pretty much all HP cartridges respond really well when the heads are placed
in about 3/4" of boiling water for 5-minute. I have restored countless HP
plotter and printer cartridges that have been open and sitting for several
years with this method. Solvents don't reach deep in the capillaries and
other areas farther back like heated water.
