Yes that’s true it’s called reverse electrolysis,
and can take up to 2 years soaking in a fresh water solution with 12 VDC
running thru the water, it works for all metals including silver some coins we
have did not even look like coins until they were conserved, now on the second
note U-Boat are cover by the war grave act if caught with an artifact
from a u boat you could face heavy fines and penalties we have to steer clear
of them for that reason, so they should be very careful conserving suc Brian CONFIDENTIALITY NOTICE: This e-mail message, including any

[mailto:owner-personal_submersibles@psubs.org] On Behalf Of ShellyDalg@aol.com Steel that's been submerged in salt water for a long time goes to
hell quickly when exposed to air unless it's been through a preservation
process. It can take up to two years soaking in tanks and I think there's an
electrical current and chemicals involved. Think of all the old Spanish galleon
cannons and how crusty they get. Look at some of the cannons and anchors
sitting out front of scuba shops and restaurants in the Florida Keys that were
hauled up years ago. There's not much left of those old relics now because they
didn't get the preservation done to them. Frank D. |
