Chrome Deplating

Post by Jeff PT403 »

I'm trying to remove the rest of the chrome from my port lights. I'm using muriatic acid and a battery charger set at 2 amp.
It works good while it's running but the charger keeps tripping out. Any solution? Thanks.

Well, usually people are trying to get chrome onto stuff. I don't know that acid and an electrical charge will erode the chrome exclusively. If there are other metal parts it will all dissolve together.

It does work, I have four done already. It's just hard on the battery charger.
After four it burnt out.

I used a wire wheel in a Dremel tool and scrubbed it off. Did all the chromed ( read measled) bronze on a Vanguard 32 that way

You must of had silver paint on yours, even on a big grinder with a wire wheel it does nothing to the chrome.

lol- in 1962, Pearson did NOT use silver paint on chromed Bronze. It was all messed up from years of exposure- that part peeling, part speckled look. And yes, it was a lot of work. But yes, I used a Dremel. Now thinking back, I may have had a sanding drum mounted part of the time.

Thanks for your help. I got it to work now. A electrician friend gave me transformer that works great.
In less the 30 minutes it comes out nice clean bronze with no residue.

Could you please describe your process for removing the plating and possibly post a schematic and specs for equipment used?

Thank you.

Here's how I did it. I got a big enough tub to set the frame in. I used Acid Magic 50/50 with water. Acid Magic is made by
Certol it's Muriatic acid but no fumes. I made a copper ring the same size as the port frame so it would draw off better.
I ran a copper wire on each end and tied together outside the tub. Then I hung the frame just above it in the solution
with a copper wire on each end. I started out with a battery charger set a 2-amps. The problem I had was it kept tripping
out. I got a couple done then, bypass the internal breaker and let it run for about 10 minutes at a time but then it burnt
out. The new transformer work great, It takes about 1/2 hour now. When I did the battery charger I had negative on the piece but when I switched to the other transformer I had to use the positive side because it started copper plating the frame.
It's pretty simple. Sure I couldn't get the picture's on.

Thanks Jeff. I have six 2 speed self tailing Lewmar winches with plating that is in poor shape. I want to remove the plating from them in preparation for re-plating. I appreciate your information on removing the old nasty finish. Thanks again for your help.

or you could take the parts to a chrome shop. they'll hang them in the tank as cathodes instead of anodes. nominal cost.
