Frozen integral 22 suppressor.What solvent? suggestions?

[Vernix]

I've had a Ruger Mk I .22 with an integral suppressor for years that functions great but it's been way too long since it's been dissassembled and cleaned.
Any favorite solvents with which to fill it since firm pressure fails to get anything moving/unscrewing/etc!

I don't want to use excessive force.

It's maker was a local manufacturer out of business for years and it surely could use a good cleaning if it's not too stuck.
It's an old simple baffle design and I'm pretty sure it's a mess inside.

I'm far from an expert, but I've had luck with stuck suppressors using WD 40 or PB Buster (I think that's the name). On a stuck QD suppressor, I set the muzzle in a cup of it for a couple hours and it came right off. For a stuck 22, I soaked it overnight and was able to loosen the end cap the next morning. Any penetrating oil and a couple taps every now and then should do the trick.

Bah... no WD40 please. PB Blaster is great stuff, tho. Could try CLP, too.

Kroil oil has worked wonders for me over the years.....

Thanks for the suggestions.
Just got to thinking about it, and am wondering if there's an advantage to using bore cleaner that's made, by nature, to dissolve lead and powder fouling.
Something like good, old fashioned Hoppe's #9 ???

Before using solvents make sure you know what the silencer is made from and whether that solvent is safe or not. Ie. Is it aluminum baffles or stainless, or are O rings present?

Metals involved.....er.....I'll know once it's (if it's) apart.
Are there solvents with damaging to aluminum of which I should be aware??

O-rings a decade old I figure aught to be replaced if present.

Thanks and any and all advice appreciated.

Before resulting to solvents. Why not take it to the range, heat it up with some rounds down range and while it is hot try to remove it. Heat does wonders towards getting things loose and the rounds will not damage or alter anything. Then after you have a look inside,,, choose your solvents.
