I don't know about you, but when I bought my bottle of RMA flux, I bought the dispenser bottle with the stupid metal syringe at the tip. As you all know, this clogs up real quick and builds up a bunch of gunk. Now I just use glass eye droppers from the pharmacy to dispense the flux. Easy to clean too, doesn't clog.
Have a heat gun? Hit the tip with that for a couple seconds.
ANYTHING will 'clog'. RMA flux has a vehicle. If that vehicle evaporates, all that is left are solids. That vehicle is IPA.
If you use it to thin or correct the mix of the flux, only use 99%, not the 70% rubbing alcohol stuff.
So, a quetip with alcohol should cut the external 'bulbs' hanging on the tip. Warmed alcohol will work by simply dipping the tip in it. May take a few dipping event to free it, but it will.
Sure, I used to heat it with the iron. It's just more elegant to use an eye dropper. Suck, dispense and that's it. Cleaning something like an eye dropper is a lot easier than the stupid syringe.
Sure, but you're still left with a dirty, inelegant, sticky and gummy bottle that suddenly dispenses a lot more flux than you wanted. Eye droppers for 1$ for the win!

I prefer a short camel-hair paintbrush. Cement it into a cork and use a tiny bottle... looks like nail polish applicator, but if you're mean and ugly like I am no one teases about it.
