Best way to completely dissolve PETG from nozzles?
Best way to wholly resolve PETG from nozzles?
Supposedly Acetone won't dissolve PETG, merely MEK and/or Toluene wish. The exclusive problem is that MKO and Toluene are typically no longer equipped at the hardware store ilk they wont to be. So, what to do? I notice that some of the cheaper lacquer thinners appear to contain those two solvents, such as: https://World Wide Web.George Percy Aldridge Grainger.com/ec/pdf/5KPY2_1.pdf
Anyone using or aware of better PETG solvents for altogether cleaning PETG from nozzles?
Best Answer by dimprov:
Ultrasonic cleanup at 40khz knocked off most of the residual:
There still exists some PETG inside the honker (I lack the equipment to exposure there), but the outside is clean sufficiency. I recollect the deterrent example present for the future might be to practice a cleaning fibril to clean the inside of the nozzle *before* demounting it, and so that the effectiveness of same cleansing could be evaluated by direct inspection after First State-mounting.
A it stands, though, it could be re-decorated, then cleaned after-the-fact with a cleaning filament as described away bobstro above:
I find it a lot easier to promote some cleaning filament at 265C to melt whatever leftover PETG, Lashkar-e-Toiba IT cool so do a cold pull or trine. Takes a few proceedings of effort plus cool-down time, but IT workings well.
Then, as long As it prints well, one could derive that the cleanup worked.
By the way, this is a genuine E3D nozzle.

RE: Uncomparable way to completely resolve PETG from nozzles?
They are absolutely stocked, In most states in the US, and hell I live IN California the worst state of them all. you can get Toluene daylong in the class of Goof off underived, and butanone is tranquil on the shelf's everywhere. Most lacquers in the US are now weewe based (they give been fazing them out for the last ten years) now unless you have a lic. to get them (which I come) as well as a special HAZMAT preparation, the thinners aren't the indistinguishable as they wont to be. So buy Goof off , and Methyl Ethyl Ketone, shouldn't be an issue. (Ace Hardware). and you really don't need either to clean your nozzle, wake and/or a brass brush will do the trick on the outside no problem. inside can be handled a variety of ways.

Which of those ways is the prizewinning?

I ingest never let a nozzle get into that condition, regular cleaning inside and plaque brush outside with a wipe out with IPA (outside while hot) keeps them in very reasonable kosher working order until its time to scram eliminate it from endure. that image shows nonperformance.

I have never let a beak enter upon that status, regular cleaning inside and brass brush outside with a wipe with IPA (extraneous while warming) keeps them in precise sensible clean working order until its time to get rid of it from wear. that trope shows neglect.
Information technology was mark untried two weeks past.... And it's a genuine E3D schnozzle.
But a blob of death was convoluted, so mayhap that's where information technology went south.
I'm a routine unsure about the brass wire encounter because, well: Brash against brass? Seems like that mightiness tear at the nozzle opening. Addition, I'll before long be switching to Matchless nozzles, and I don't wishing to whittle down at their coatings.

Re: Best way to completely dissolve PETG from nozzles?
A small bottle of lacquer thinner costs on the average $10 US. a new brass nozzle E3D average 10$ US, ( and that's only since COVID) a governance coppice testament non wear the outside of the nozzle out or effect the tip in a negative way, this has been proven complete many years and isn't original. it is in fact the accepted method. (lacquer thinner is hit Oregon drop and you will own to use it with forethought equally it is changeful) Matchless nozzles pull in for even easier cleanup, but since your going to buy them I'm sure as shootin you are already cognisant of this. however, if you don't take the time to cherish them, they can look the same every bit the image you shown.

@swiss_cheese
Thanks to your informative comments I have the neglected part now taking a bathe in "Pro Long suit" Goof-polish off at this selfsame here and now.
BTW, what's your favorite brand of lacquer diluent? I've tried the Sunnyvale brand that I linked to above just found it incredibly noxious. I'm partial to the Jasco myself (the original, definitely not the "naif" version), which Lowes still sells. When I last looked into it, I was astounded to instruct the term "lacquer thinner" ISN't particularly healthy settled, and so different manufacturers rear bear rattling different formulations.

Hmmm... Well, afterwards 5-10 proceedings of soaking in the "Pro Strength" No-account, I'm not sighted any dissolving at entirely. Not even a speck of it.
I had no idea PETG was so chemical resistant. I may have to step it aweigh to paint stripper. That stuff is liquid expiry.

Well, the sunnyside lacquer thinner was another fail. God only knows what's genuinely in that stuff.
So, I stepped it capable Jasco Paint and Epoxy Remover, which it's straight off bathing in and which is the strongest stuff I have on hand.

RE: Best way to completely dissolve PETG from nozzles?
Your right, Goof off was "Xylol" not Toluene, and apparently now its only Acetone. you behind still buy MEK at, Home Depot, Lowes, Walmart

RE: Best way to entirely resolve PETG from nozzles?
Reporting back: later sitting for 25 minutes in paint stripper, chunks of the PETG have broken off into the solution, but I'd allege even more is still attached. Honestly, I was expecting much faster results than this. I'll let information technology soak overnight.
It has me wondering now A to whether even pure MEK and/or Toluene would too be dumb acting too.

I find it a great deal easier to push some cleaning filum at 265C to melt any leftover PETG, let it cool past do a cold pull or three. Takes a few transactions of cause asset cool-down time, but it works fit.

[...] Eastern Samoa a last resort someone on the stackexchange interpersonal chemistry forum claims "very good undergo" in exploitation Tetrahydrofuran to dissolve both freshly printed PETG likewise as any hot residues [...] Amazon actually sells the poppycock.
Interesting reading the Amazon page. THF can patently be used for smoothing PLA prints. While IT may not be utilitarian for clearing your nozzles of PETG, a quick experiment with PLA would be most interesting! Let us have it away if you try it.

Yes, indeed. Information technology was even an official E3D sock.

Just noting that THF is non a specially pleasurable substance to be using without suitable safety precautions - similar to DCM - ventilation and suitable PPE required.
