Suppressor has some rust, what now?

[Mackie]

So, I have been an idiot last week.

My suppressor had some dust, and I decided to wipe it off with a damp cloth. Not much can go wrong, except if you have fat idiot hands, and doing above a basin full of water.

So I dropped it, it submerged in water. I tried drying it to the best of my abilities, but no... Today, I saw it had some rust.

What is your opinion, safe to shoot for this season and replace after?

I have no experience with this, but there are ways to clean a suppressor.

My first thought would be to perhaps drop it in gun oil and have it sit for a while, then let it drip off.

Soaking in ATF works better than oil, in fact google the recipe for Ed's Red it's very effective for suppressor cleaning and can be homemade.

I regularly throw my Ase SL5 in my sonic cleaner with Hornady Metal cleaner.
But I heat the Sonic cleaner water.
Afterwards I blow water out with compressor and air.
Then put in our Microwave/Convection oven on about 140degrees for 10minutes.

I would take your silencer to someone who does sandblasting. Stick nozzle in one end and let blow.
And hopefully Sand will reach all the baffles and remove it for you.
Afterwards get some oil in it.

Heres also an option.
At our local hardware store brights.
They sell a liquid that you dilute with water to remove rust.
You can wipe it on or soak item in it.
This will remove all the rust for you inside and not damage metal.

Ive seen on the knife making shows. People throw rusted steel in vinegar.
And it also eats of the rust.

Make a solution of warm water and citric acid, let the silencer sit submerged in the solution for a day or two.
The rusted areas will start fizzing like Cal C Vita.
Periodically check on it.
the rust will be all removed after it stops fizzing.
Remove from solution, rinse off with clean water, shake it out to dry and either pop it into a warm oven that's switched off or leave in the sun to dry.
Citric acid solution actually passivates metal

And it leaves the metal looking a dull silver grey, a bit like anodized aluminium

Just spray some moisture displacing penetrating oil in there. WD40, Q20, Spanjaard Spark, etc. Then, whenever you get the chance, shoot it. After shooting, just spray it again. The supressor will still last a lifetime. The thin surface rust will not affect it in any way.

Next time you want to wash it, dissolve some water soluble oil in the water. That's the stuff used with the cooling water on a lathe or mill. When the water evaporates, it leaves a thin protective film of oil.

Or you could wash it in parrafin or kerosine with a little oil added. Even Diesel fuel will do. I would not use any agressive cleaning solutions.

What about putting it in some boiling water to convert the rust into black iron oxide, a la rust bluing? Followed by a light coat of oil.
