What type of filament? Acetone doesn’t do much to things like pla or petg, stuff that works aren’t things you generally want around the house, industrial solvents and stuff.

Cold pull as others recommended, nozzles are consumables, def should keep some around. Cleaning filament works pretty well in my experience if you have a partial clog. Have had some success soaking partially clogged nozzles in acetone (not the best but it’s something with long enough residence times), but that won’t get you up and running today.
