| When I worked with a shop that did nickel, chrome and hard chrome we would simply unplate it. DC current when had a power source but a car battery would work. + side to the part - to a piece of lead sheet and a sulfuric acid bath. Would just take a few minutes. I bet a plating shop would do it for you easier than setting up to do it yourself.
As usual just my $.02 Paul K

| If it is crappy plating a light bead blast may stess it enough to peel off.
Otherwise there are chemical recipes that can strip it.
There is an ammonium nitrate based solution which operates at a pH of about 6 and is quite fast.
Try the Electroplating Engineering Handbook. |

| Ramrod is right , just deplate it .When you do serious plating as with a good hard chrome , they first deplate which remove oxide. dirt etc, then plate .That's because the trick to a good job is to have a "chemically " clean surface not just a soap and water clean one . |

| That is the same process as electropolishing. All of the more active crap on the surface is removed first. I think what you get is atomically clean. quote: Originally posted by mete: Ramrod is right , just deplate it .When you do serious plating as with a good hard chrome , they first deplate which remove oxide. dirt etc, then plate .That's because the trick to a good job is to have a "chemically " clean surface not just a soap and water clean one .

| Brownell sells unplating solution (or used to anyway). I use it to remove the chrome plating from chokes and forcing cones in shotgun barrels. As I recall it was a pretty simple process. C.G.B. |

| Come on guys , use the right words ! It's 'chemically' clean not atomically , and 'deplating' not unplating ! |
