Chemical Etching (or stripping) of Chrome



Sund. June 29, 2003

Hello

I welcome your help in finding information about
environmentally friendly chemicals for the removal
(or stripping) of chrome. The chrome has been plated
on surface, which could be a non-metal or a metal
surface like steel. This removal process is sometimes
called "Chrome Etching" or "Chrome Stripping".

Traditionally, hazardous chemicals were used to etch the
chrome. I believe one of these is cerium ammonium nitrate.

We are trying to collect information on
-  Hazardous chemicals currently used for chrome etching
-  Any more environmentally friendly substitute chemicals
   that are or could be used for chrome etching.

I welcome your input and comments. Thanks.

Have a nice day.
