Hi guys, a couple of days ago got this poor relic. A MP41, found in a forgotten forest hide-away. Was it hidden by commie partisans during the WW2, or shortly later by anti-commie people - this will never be known. Anyway, a poor old MP41, by Haenel /after a couple of hours in electrulytic bath even the letters ontop of it apeared!/. In the summer will try to heat it and restore the shape, notice that it is a bit off the straight line to the back of the magazine slot. Also will try to convert some rifle wooden stock to fit it, not perfectly, but to give the look.

If you keep it a home, at normal humidity, away from rain and moisture, I think it does not need treatment. Or just oil it, with light, "thin" oil.
I used electrolytic cleaning on the MP41, but the metal is still very hard, even the places made of thick tin are very strong and sound - there was lots of rust, but mostly surface, not deep in the metal.
The electrolythic method is a great one, the electricity removes all the rust up to strong metal and does not damage the metal. BUT it is absolutely not good for highly corroded things - it removes all corroded matherial, so in result you may get a badly pitted piece of metal, hard to recognize what it is.

If the rust is still "working", I think oil is the right thing. But not WD40 and similar stuff - it seems quite "agressive", when I have used it on rusty things, it well removes some of the rust. So, it may cause further pieces of matherial to fall.
Another approach is treating the rust with some acid /forgot which.../ and after some neutralization - coating the thing with glue-like stuff, to prevent both from moisture and from losing more pieces of the matherial. But this needs some special chemicals - and of course a better explanation than mine
I say my opinion, but look for more opinions, before using even the most harmless oiling method

Many thanks. I have heard about preservatives used to 'stabilize' rusty American Civil War era relics. Prehaps someone else will comment.
