I've done it with my Guardian 22. My biggest issue has been finding a blaster with a nozzle that is small enough to be efficient.Soda blaster. Has anyone tried this?
Some of them allow you to remove all of the baffles to clean them.I can see the blast baffle getting clean, but all the other baffles in the stack? They're physically shielded from the blast, so how do they get clean?
I use this DIY soda blaster and it works great.

Get the soda from Harbor Freight if you have one nearby. It is a heavier grit and works much faster/more effective than the grocery store stuff.
