I started out bead blasting it just to etch it up some.
I have a chrome plated breather cover off an old car that I am powder coating.
You have correctly identified the cathode as the negative terminal (I like the mneumonic 'andode & canthode' to remember the plus and minus), but you have the terminals reversed in your description because the item you want to de-plate must be connected to the positive terminal so electrons are removed from it causing the metal to convert to positively charged ions. Check the part regularly and be careful this stuff is dangerous! It's called electrolysis and is the reverse of how they chrome plate. Hook the anode or positive terminal to a lead bar or just something lead and submerging that to. You can use sulfuric acid to remove chrome by submerging your part in it and hooking up a car battery to the part. Sulfuric acid is used in chrome removal as well as car batteries. This was most likely not due to the cleaner but due to the sulfuric acid in the battery corrosion. If that actually works, I'm impressed! Chad KellyĪ. the repair shop my dad owns is strictly mechanical, body repair is just hobby of my own, so I have limited resources of which to use) Any ideas? Terry Knutson I was wondering if there are more abrasive mixtures available for the sand-blasting method (other than glass beads)that anyone has any experience with. I used a resin pad on an air tool to remove the rest on one but it left the aluminum shiny and chrome-like, I am now trying to find a better way to rough up the smoothed aluminum while also looking for a different method of removal. I tried sand-blasting them, and it worked great to take off the majority of the chrome, but had minimal effect on the sides and edges which weren't peeling. I work at my dad's repair shop and stayed after hours to try different ways to get it off, and so far have been somewhat unsuccessful. I recently bought a set of Keystone Klassic rims which were chipped scuffed and the chrome was peeling on all of them. Sounds like shiny chrome-look paint or PVD Chrome. If there's black paint underneath, they certainly are not chrome electroplated. The wheel that has started to peel has what looks like a nice smooth black paint underneath so if I could get the chrome off myself I want have to get repainted as I wanted them black as the chrome is terrible.Īny help would be great. The other 3 wheels are fine but now I have 1 bad one can anyone help with ideas for a D-I-Y strip that won't damage the wheel underneath the chrome. Can anyone help: my car wheels are chrome plated one has started to peel and it's peeling off like wall paper. J- this entry appended to this thread by editor in lieu of spawning a duplicative thread have heated up chrome plated emblems with propane torch and the chrome starts to flake off and Shrink then fell off Michael Baltzer Maybe you successfully burned off shiny chrome-look paint? I personally don't think you can remove real nickel-chrome plating that way.Ī.
I have the same problem, and I cannot find out how to remove the chrome but so far I been peeling some off, but can't get the rest, I'm going to go to couple body shops and ask, but anyone else has a comment bout them reply here. First it wasn't long enough in the acid then I tried it again after cleaning it off then I let it sit for 15 min and it turned it black it cleaned up after sanding but was pitted and no longer usable I have also tried a grinder and am afraid to go too far and hit the aluminum. I have tested this on a chrome plated thermostat housing and the results were not good. I am wondering if there is another way other than I have recently been given some rims that the chrome plating on the Aluminum rims is peeling off. How to remove chrome plating peeling off of rims!Īn ongoing discussion beginning back in 2006.
