I noticed that Loki doesn't offer the polished graphite nozzles anymore, what is involved in cleaning the non-polished nozzles?
I talked to Scott about that. It’s a lot of work to polish a nozzle and they’re all done by hand and time consuming. I’ve also bought both polished and unpolished and right now I can’t tell the difference after several flights. And like heada, I don’t bother cleaning anymore unless there’s a lot of slag.I noticed that Loki doesn't offer the polished graphite nozzles anymore, what is involved in cleaning the non-polished nozzles?

Ohh man,
How nostalgic is that..
Raceway Park expanded and built track after track..
All my life growing up it was a dragstrip next to the Englishtown airport..
Then they started expanding..
I kind of think one of the things that played big role in them closing their doors was
a driver loosing his life at a national event there..
They were open for a few years after that but then eventually closed their doors..
That place was simply a part of life in central New Jersey..

In any case, no matter what you do, no liquids! Carbon nozzles soak up anything like a sponge, especially water, and will crack on the next firing if they've been soaked. Store it clean and dry, like you would store a reload.
i was not aware of this
i have sprayed mine with a little simple green on a few occasions
guess i should stop doing that
Yes. Stop doing that. Liquids of any kind, ESPECIALLY water, are a no no with graphite nozzles. If it's been a long time since in a relatively low humidity storage location, probably OK in the short term, but certainly bad practice.
What about wiping the nozzle with quickly evaporating solvents like alcohol or acetone? Not saturating the nozzle, but merely wiping it down with a rag that has some solvent on it? If the risk is that the graphite absorbs water and then cracks/explodes later because the of the steam produced by the high heat, it would seem like solvents pose little risk as they evaporate very quickly.
Having said that, I understand the preferred method to clean the nozzles is dry scraping with a blade or screwdriver, just asking more as an academic question of the risk of using a solvent with graphite nozzles.
not doubting Banzai88 , but I have alwas cleaned my noozles in the sink with dawn and a scotchbrite. No issues so far but they do go sometimes years between uses.
I was about to say that the 38mm G motors I purchased included them, but now I realize I can't remember if they came with or if I added them on when I ordered the motors?That’s why I like them. Only downside is they don’t come with starters so you either have to learn to make your own or buy at additional cost.
it does not take 2 min to polish the inside, also depends on if you use iso molded graphite

I myself have never heard of it. I used to soak nozzles in vinegar over night. Never had one crack or break.in all my years usung graphite noozles, this thread is the FIRST time I have ever been warned against using water to clean-up.
