firstly, you are required to inform the RECIEVER OF WRECK of any article you remove. regardless if you found it on the sea bed.
They sometimes let you keep the object as long as it has no value for history or past military encounter.
If it IS a sten gun, then id certainly inform the local coastguard as if you are caught with it, youll be liable for many offences!

We do not advise anyone to remove objects on dives, simply because if left alone, they become dive interest for other divers, life sometimes utilises the object, and if it has been submerged for a long period, then bringing it to the surface will no doubt start to destroy it.

Ah right good man!

If it is something that isnt readily identifiable, youre not in any danger i dont think!!

As for removing the metal from the crud, this is a tricky thing.
Dependant on how long the item has been submerged in the sea water for, depends on how quickly it will deteriorate in air. Obviously the sea water will start the oxidation process but while kept underwater, the oxygen level is lower and this process is a lot slower. Once you get it on dry land, the air around it will speed this up considerably.

Secondly, what is the CRUD? is it hard matter, I.E mineral formation? or is it softer matter, like mud, organisms, or sea kelp?

Both need care to remove the object without damage.
