Cleaning white residue off tanks.

[Linedog]

Hello all, I just aquired a set of Worthington 130 cold galvanized steel tanks. They were set up as doubles and have a white film left over from the bands. What is the best way to clean it off?

Take them diving a lot for a couple of years and the lines will become blurred. That is what I have done to make the area where my HP130 used to have a Nitrox sticker blend in better.

Worthington only cold galvanized lp77's. These are hot dipped galvanized tanks and the white areas are where the zinc has oxidized. Rubbing compound, scotchbrite pads, or steel wool will remove them, but in my opinion that would be a mistake. You will also be removing some ot the protection the zinc gives your tanks. Do what you want, just giving fair warning.

Well, I scrubbed last night with a green scotch brite and a Mr clean erase, only a slight bit better. I think I'll try a little more and then just live with it, I don't see it when I dive anyhow!

Agree, if the bands aren't going to be replaces it will fade away in time. Removing it just reduces protection.

OK I'll just let them be. Less cleaning more diving!

It could be salt build up or corrosion. If it is the later you need to stop it before it gets worst. Give it a good rinsing and take brush to it to clean it.

Sounds like a damn good plan to me
