Who uses Great Stuff the foam insulation in a can? I like the stuff and it works great. I just don't need the entire can for most jobs. What is the best way to be able to use the can and spray nozzle again? It seems no matter what I do it's clogged next time. Even if you use high pressure air to blow out the tube and clean out the can tip with a wire it seems to never work again. I can't find any solvent that will dissolve it.
acetone will clean out the tube, but you'll most likely never use the can again. they're a one shot deal AFAIC
There is a slim chance that you can use a can a second time if you dismantle the nozzle, can and straw. Poke a pipe cleaner through the nozzle, and through the straw- and a 3d one into the end of the can. Pull them out when thoroughly dry.
I used to do that & sometimes I saved a can. Now I keep a tally of where I need a partial can & never use it until I can empty a can. If I just need to do that 1/2 can job, I fill cracks in the cement floor of the garage, or cavities in the block out there. Makes me feel better about not throwing anything away. [but in the big scheme of things a 1/2 can is $2 or so, and I've probably wasted $2 once or twice in my life.

It would mean buying a few more things, so you need to decide how big a deal this is to you.
Buy a cheap gun, $20-30
I've been running the same gun for years. The foams have a shelf life, so they can't just sit around for years. In fact, it would be best to buy from a supplier who goes through lots of material. There is a refrigeration company here that uses the one I use, so the suppliers stock is always fresh.

Acetone cleans uncured product. Once dry it can only be mechanically removed. When you clean out the straw, make sure you clean out the thingy it's attached to and also the top of the can where the thingy screws on.
Seems to work for me.
They used to come with an instruction booklet and a pair of plastic gloves! The official way to do it, and it works very well, is:
Dampen several toothpicks (flat ones work best). Pull everything apart. Insert one in the nozzle on the can (large end of the toothpick into the nozzle), and in each end of the dispensing tube and the plastic adapter. When the GS has dried, it will pop right out when you pull the toothpicks.
The way I usually do it is to spritz some acetone into the nozzle and tube using a lab bottle with a small nozzle. This works fine.
