Can anyone please tell me the best way to de-Chrome plastic parts, I
have been told that brake fluid is good, but needs to be handled with
care in case it eats the plastic. Any hints and tips would be
gratefully received.

Thanks in advance.

Doug.

Hi Doug,
A somewhat less caustic method is to mix up some powdered detergent
like Tide with water to a consistency a little thinner than toothpaste
and soak the part or parts in it for a day or so.  The "chrome" should
peel or flake off with a little urging from an old toothbrush and warm
water.

Get an old bottle of mayo and fill it up with good ole household bleach.
Drop your chrome parts in it and leave them there for about 24 hours.
Should dissolve all of the chrome - not the lacquer used as a smooth
surface for the chrome to adhere to.  If you still have some chrome
attached, repeat the process again and with rubber gloves on and an old
tooth brush, brush away the remaining chrome.  If there is still some
chrome left on the parts, get your trusty No. 11 blade and gently scrape
the pesky non conforming chrome off.  Works for me all of the time.

Good luck.

    I have not had any problems with the yellow can of Easy-
   Off oven cleaner.

    Apply to one side, let sit over night, repeat to the other
   side. May require additional applications to get all of the
   chrome off.

If I am going to paint the part, I do not bother to strip the chrome.
I prime with Krylon primer, and it seems to have enough tooth with the
metal that it does not peel off with reasonable handling. I then paint
over the prime, and have had no problems.

Many thanks to all of you for your help in this matter I will give
most of them a go and compare the results. I am always impressed by
the help given on this message board and would like to thank you all
again for your help.

I have pieces of model kit that are chromed and have been painted
sitting in a tray of Simple Green. They were not needed parts, but some
that were painted for testing purposes.
They have been sitting in simple green for weeks. I can tell you that
they are clean as a whistle, but sill painted and chromed.

...While I've never actually stripped chrome myself, I've seen others
do it, and the catch is that the chrome can't be too thick, and you
need to keep the SG slightly warmer than room temperature. IIRC, about
80F will strip the chrome away in about a day or two with no damage to
the parts.

Doug,
there are plenty of older UseNet threads covering this subject. Here
is one:
