Brass Nozzle Cleaning.
I am noob. Is there anything I can soak a brass nozzle in that will EAT PLA or PETG out of it and off of it? I have a lot of build up and am tired of buying more nozzles.

RE: Brass Nozzle Cleaning.
To clean the nozzles, simply leave them installed in the extruder and heat them to approximately 230 degrees.
You can then use a wire brush to remove the soft filament, leaving them looking like new.
There are a few reasons why excessive filament may accumulate on the nozzle.-
- The flow rate is too high
- The filament is not dry
- The retraction speed or retraction distance is too small/low

Echo the above. I use the same nozzle for years (just PLA) and it looks completely clean even though I've never touched it! I do check and use needle nose pliers to pick off any plastic immediately after any print though...... lol, but saying that, even that's rare. I do find PETG more 'messy' to work with though - but then again, I never really dry filament.....

While hot, as mentioned above. Been using round tip tweezers for years, grab any ozze before/after the print and anything left on the nozzle. Don't bother with a brass brush.

So we heat to 230z… then what?
RE:
My suggestion is to go on to Printables, find a Core One nozzle wiper (there are a ton of these, just pick your favorite) and use it to automatically scrub the nozzle between printers.
This is one I created to specifically to be out of the way and also work with BIQU Cryogrip sheets: Core One Universal Nozzle Wiper Use the right-hand version if you have the Core One+ automatic vent upgrade.
Why Prusa doesn't have this as standard (everyone else does) is beyond me...

Regarding "out of it": Have you checked "Cold pull" procedure? It's easy to find a better explanation than I could write up here in a few lines so I won't try (in a nutshell, the trick is that moderately hot PLA gets extremely sticky). Surprisingly efficient.

Remove the material stuck to the nozzle
