OK, let me step in here at this point. Someone may have already
mentioned this but chromium can be very, very toxic. Cr(III)
(trivalent, or chromium 3+) is not too bad, but Cr (VI) (hexavalent) is
a known, proven carcinogen (primarly giving lung cancer).
OSHA page: www.osha.gov/SLTC/hexavalentchromium/
It will mess you up, and it will mess up the environment if you pour it
down the drain. Heck, you can put your local sewer treatment facility
out of business for awhile if you flush enough of it. Cr(VI) is mobile
in the groundwater, so if you bury it, it just moves to your neighbors
land. You will be financially liable for remediation costs.
It's easy to accidentally ingest, either by breathing it or swallowing
it (If it gets on your cigarettes or you hands).
Bottom line: Let the pro's do it- they have the equipment, and they can
give it to waste disposal and treatment facilities.
Trust me on this, I'm a University Chemistry professor. I don't want to
see anyone hurt or sickened.
Greg- this isn't aimed at you personally- I'm using the general 'you'.

Hi Ted, I, too, have been interested in a chemical or electro-chemical approach to chrome removal. There isn't much information online about homemade techniques and I have to think at least one reason is the health hazard. I recently found an article online describing how to strip electrochemical plating (like chrome, nickel, and brass). I've not tried it, but it sounds promising. Here is the link in case you are interested: http://www.docv.org/articles/strip.htm Tone Deaf Touring wrote:
