Hmm the docs mention Attar-C and DOT 111/113. I dunno what it is and it’s almost 5am for me. But on the whole I must not overthink this … I must not overthink this… Zzzzzz!
I have no clue either what these proprietary compounds/mixes are..

Again I just use the easily accessible stuff (if the reg is in a bad state and even needs all that): water , soap (to degrease/pre clean), vinegar/ phosphoric acid to etch corrosion and backing powder (to neutralize the acid after)

Keep things diluted enough (with acid) and it’ll all be alright — you mentioned that they’re in a good shape, probably water is all you need

Let us know ;)

I’d like some ZZzzz too tbh, night y’all

You know the hardened grease and rubber buildup that stops your spg from sealing

Well some toluene on a cotton bud on a stick cleans it out very nicely thanks muchly

Careful with toluene cause it can damage rubber hose.

I am the one dishing out the advice here, what rubber hose are you talking about, man

This is why we are here, to dissolve desealing rubber and grease

Do you see me pouring gallons of rubber munching toluene down a hose with a funnel

Fortunately the spg is toluene proof inside all the metal bits, too
 
Yeah I would just use BIOX it's what's reccomended for apeks regs at least. It seems expensive but you can make it last ages. I mix 250ml with 1000ml distilled water (doesn't have to be distilled just slight gain in the ultrasonic efficiency). After servicing the regs I keep that used biox for the 2 years between servicing for odds and ends (like cleaning the din threads in reg adn cylinders a 1-2 times a year), then I use it as a pre wash to my next servicing, i.e. before sonicating my parts I leave it to soak in used biox/water mix. By the time it gets to the sonicator most parts are already shining. The other thing that makes a big difference is to get a sonicater that is heated.

You could probably dilute more than this but only if you are prewashing and using a heated sonicator. But even at this dilution a 5L bottle of Biox is 20-40 years of servicing for me with my 4 sets of regs.
 
This is all pretty amusing, vinegar has been doing a fine job for many years, just get an affordable US cleaner and go for it.

I seriously doubt your regs need service anyway, have kept an eye on the IP?

IP was good. I even opened them up and rebuild and checked them in a live classroom session without replacing with new parts (an mk19evo, mk25evo,s600 and a c370). Only the Apeks Xtx50 has been left untouched but I plan to do it at a later date without the formal Apeks training class by watching YouTube videos. I even got the special lever height adjustment tool for it.

But now that tear down and rebuild means the seat imprint may be just finely misaligned (at least one of my 2nd stage has two mostly overlapping circles on the soft seat just slightly off by a hairs breath (a source of potential leak?) . In any case I don’t want to just leave them unserviced for 3-4 years and keep diving. Some of the high current dive sites I’ve been to really scare me just thinking about equipment failures when fighting currents. All said I also needed a new tinkering hobby so it’s all fine and worth the investment in time as well as in all the speciality tools I got for servicing.

If you removed the diaphragm on the 19 and put it back in, you need to service that one before using it again. The SP seats for the second stage are easy to replace (stupid expensive for what it is but still easy to keep a few around and change as needed.) I don’t service my own stuff until it needs it and there is no schedule that makes sense that I’ve found.
