Excessive salt deposit resulted in brass exposure

[nikolay_zhelev]

Hi guys,

I started servicing Scubapro G260 (bought second hand) and found that it has been flooded with salt water.
I’ve cleaned it perfectly, but after the US cleaning the bare brass came out under this salty deposit inside the crackling effort adj. knob and around the tube thread. Now I can’t decide wether to replace the affected parts or service it as it is and dive with it.
I’m open to your opinion.

And that’s the result after cleaning:

From a function standpoint, it's just fine after your cleanup. Nice job, by the way!
The chrome serves (or served) as an anti corrosion layer. The verdigris will be worse on the bare brass, so the regs now need a fresh water soak after each dive trip. But there's no reason these shouldn't still last decades.

Of course, if perfection is a thing for you, then by all means put new bling on your regs with replacement parts. But if the micro adjust screws in and out easily after lubing the inside of the knob assembly, then after service the reg will perform just as well as it did originally.

Ah! Happy diver beat me to it!

Looks okay.
It's pretty normal that using the US with an acidic liquid can lead to a cleaning which apart from removing salt residues also removes parts of the chrome layer on the affected parts.
That's practically no big problem, but from now on you have to check the lubrication a bit more often, because without the chrome all dirt and salt will stick to these parts more easily and stronger.
Since the parts shown are static after adjustment I would just clean it as good as I can and lube it well and you are ready to go ( the manual you have already).
Good luck!
Ah, the usual suspects are very fast as always......
Are you guys never sleeping.......?

Ah! Happy diver beat me to it!

But never as succinctly as you man

Hi guys,

Thank you very much for your quick feedback!

I’ll service it as it is and dive with it.

Happy diving to all of you and get some sleep

The original owner didn't wash or soak his regulators in freshwater. #4 is correct. Your regulators should function with no problems. I use 50/50 white vinegar and water.
