Just had quite the battle with a clogged up spray paint can. Something
(paint solids?) was clogging the tube that goes up tube in the can. I
though it was the nozzle at first, so I tried another one.

Short story is brake cleaner will REALLY clean those nozzles out fast. A
little spray and a few minutes will make dried enamel just flakes off
those nozzles too.

It works way better than a soak of mineral spirits, which mostly does
nothing to dried paint anyways. Since many cans now spray upside down, the
old trick of clean out the nozzle with just some propellant doesn't work
anymore anyways.
