How do I clean my galvanized doubles?

They have what looks like oxidation buildup where all the stickers used to be. Like a buildup of white. Can I take a wire wheel to them. Takes way to long with a wire brush. Any suggestions without compromising the galvanizing? If you look at my profile the first couple of pics are these tanks. Any help would be appreciated.

I would have somebody glass bead blast them.

Would that take the galvanizing protection off? Sorry I’m not good with this.

And who does glass bead blasting and how much?

Glass bead blasting is very gentle to metallic services. You could also try soda blasting. You can buy small hand held blasters that run off small air compressors. Google it. Otherwise take them to your local shop and have them send them out for cleaning. It looks to me that the stickers that use to be on there caused the build up by trapping water behind them. A little Vinegar or CLR might actually do a pretty good job.

Question. I have a small angle grinder. If I put a wire wheel on it can I use that on the tank without taking off the galvanizing.

I would leave it alone myself. If this is a spray-on galvanizing it is no where near as durable as the hot dip galvanize. You could end up doing harm to the coating just to make it look better.

I do not think any manufacture uses the hot dip process anymore as spray-on is cheaper, easier and faster. I have no idea exactly when that changed so you would be better off asking Worthington if their tanks made in 2000 were spray-on or hot dipped.

I’ve only had my doubles in salt water a couple of times (Yes, I’m a freshwater quarry commander ;) ),... However I have some "love taps" from the FL caves to add character to mine!

I’ll admit,.. since getting my Hollis Rebreather, my sets of doubles don’t see the use that they used to get. something about 1/4 the weight & twice the bottom time, just makes the Prism2 irresistible!

Well I tore my 95’s apart and brought them to my ds. There is some spot rust in them but nothing bad. No rust near the treads. Just outside. They are going out for hydro this week. When they get back they will get a vip and o2 clean. I bought these doubles for $350. Double worthington lp 95’s, manifold, and extra large ss bands which I like. With hydro/vip/o2 cleaning I’m looking at like $180. So let’s say $530 total.

That’s not a bad deal at all when a lot of the popular sizes of Worthingtons are selling for nearly $300 a piece, then $50 for manifolds & another $50 for bands. Used Worhtingtons have nearly doubled in price since they stopped making scuba cylinders.

Honestly, and unfortunately, your best chance of getting a "cave fill" in your 2400psi tanks in NY is to take them to a shop where they don’t know what the heck they’re doing (i.e. the kid filling tanks just puts 3000 psi in everything). The lower the quality of the shop staff, the better the quality of you overfill. Sad but true.

Also, to answer the original question, DO NOT remove the white "corrosion" on galvanized tanks. It’s that controlled corrosion (galvanizing) that is protecting your tank from real damaging corrosion (rust). Don’t try to erase it, just embrace it.

If you really want to make the tanks a uniform color again, just buy some ZRC cold galvanizing spray and give the tanks another coat on top of what’s there. This will also fill any scratches that may have defeated the galvanizing in spots.
