How to clean this shell?

[conimus]

Hello,

Today I found this shell in the woods in Poland and I would like to know how I can remove rust and dirt from the shell without damaging it?

Thanks!

Greetings,

This could still be a Live Round, is it hollow? If not I'd suggest to call bomb disposal.

Yes it's hollow… Otherwise I would run far away from here...

Electrolysis using a car battery will shift alot of crud from it.

[conimus]

Yes I will try that…

You might also want to ask member AT P SWEEP. He detects and cleans up his items really well
