Stripping chrome off plastic

I have searched both here and the old interwebs and can't find a good way of getting the chrome off my cluster bezel.
Does anyone have any advice? I have tried bleach and drano with no results. Going to buy some oven cleaner on the way to work tonight and try that too.
Advice??

Thanks
Keith

Oven cleaner may eat the plastic. It won't get the chrome off. Electrolysis or mechanical removal is about the only way.

I watched a video today on the electrolysis way today. I'm not sure I have the stuff to build one. But it looked sweet.

Its plastic chrome. Very hard to remove... Just scuff it up and paint it.

is there a reason you want to remove it? i would just paint over it if that's your eventual plan...

It's the back of the gauges I wanted to strip. Don't really like the idea of painting it because I'll be doing it every time something chips it. I have watched a few videos of chrome
Getting stripped off before and thought that it would be the best by far to just remove it.

But I think I will just paint it. Seams like a pain in the ass to strip if it's even possible.

I work with some parts that are chrome plated plastic and the stuff is not easy to get off... almost like they want it to last a long time...lol Also, all the parts I've ever seen are white plastic underneath the chrome, which I'm assuming is not the look you're going for.

You could borrow Helimech's Dremel with a buffing pad or fine grit wheel and take it off.

I have noticed most parts are white plastic after the stripping process. I just thought paint would stick to bare plastic than a chrome part.

I have a few dremels and HeliMech is a few miles away! Lol

Believe it or not, if you want to remove the chrome plating from plastic parts Coca Cola does an excellent, if a bit slow, job. I learned this while building plastic models when I needed to paint a chromed part, and the paint just didn't stick to the chrome very well even if it was roughed up first. It may help to slightly rough up the chrome with a Scotchbrite pad to make sure there is no sealant applied after the chroming process.

All you need to do is thoroughly wash the part(s) to remove any surface contamination, weight the part to keep it immersed while the stripping process is going on, put it in a plastic container, immerse it in classic Coke, and leave it alone for 24 hours or so.

It doesn't always work depending on the nature of the chrome plating, but usually does.

A couple of warnings: if there are any other metal parts cast in to the housing coat them in something waterproof before stripping, otherwise they will be etched away as well, and sometimes the plastic can be etched slightly as well due to the necessity of having to make it conductive in order to plate it. Test a small unchromed portion with a puddle of Coke before proceeding with the stripping process.

I thought I heard somewhere that strippers used a lot of Coke.

I didn't think that the "coke" trick had the power to strip the chrome after trying bleach and drano.

To be honest I'm in the middle of painting it now. Lol

Look up PlastiDip it'll cover anything. I covered all of the chrome parts on my car with it over a year ago and it still hasn't come off. No painting, scuffing or anything required.

I just ended up using dupilcolor primer and trim paint. If that stuff comes off I'll try plastidip.
It came out better than I thought. I'll have to wait for the riding season to see how it lasts.

That's the exact same stuff I used at first when I painted the trim on my car. The problem with that is if it gets wet, it'll leave really bad water spots. It looked amazing at first, but then after the first time it rained, it was faded really bad and the spots appeared.

Plastidip is hard to find around here. Everything is duplicolor. But I'm looking for it. Might as well throw a coat of it on and see what all the hype is about.

The only place to find plastidip out here is at Home Hardware. But due to the curent popularity its still impossible to find.

I have a few friends and coworkers who have used it to back out grills and rims, it works well and is durable. I have seen some things looks great & others look like shit. Just like regualr paint jobs... It still takes good prep work, coverage and patience to have it turn out well.

Just asked a few guys at work if they know where to get it. I guess it's a custom order from home hardware. It's $20+ a can. So I'll order it up and see but that's crazy money for a spray bomb.
