I had a go at some elotrolosis as I have read what the chaps here have done like BD6 I had a 2' mortar fin on a parachute flare round that was tatty rusty so gave it a whirl.
It looks brand new for a 44 dated piece uses tap water, teaspoon of cold power detergent, an allen key for the sacrificial piece all in a 2 ltr ice cream tub and 3 hours later and it was great, thanks guys.
