Yup, I USED TO pull the innards out and clean the mess up, but seemed to be almost not worth it. I have since devised a system that cleans the nozzles well and only uses 2 oz of acetone.

Here it is:

I use a small (3 ml) syringe (I believe that Horizon sells them with a couple blunt needles in them for glue application) and attach a short piece of medium silicone glow fuel tubing to the syringe. Pour about one ounce (30 ml) of acetone in a small mixing cup. Fill the syringe with the acetone and attach it to the end of the nozzle. Point the thing into the trash can and SLOWLY push the acetone into the nozzle with one hand while hold the pieces together with the other. Now stick the end of the nozzle in the acetone and fill the syringe again through the nozzle. Squirt this into the trash can. Now put the nozzle back in cup and flush the remaining acetone in and out of the syringe a few times. Discard the acetone and refill the mixing cup. Flush it in and out again and the nozzle should now be clean and ready to use another day. Sometimes, I find that a little residual Hysol remains in the very base of the nozzle where it attaches to the cartridge. If needed, I take a toothpick and remove it and then flush it with acetone again. It is important to fill the syringe before attaching it to the nozzle for the first flush. This forces the Hysol out of the nozzle. The subsequent flushes just clean the nozzle. It literally took about ten times longer to type this description than it takes to do it! It's well worth the effort.
