Sodium hydroxide at 8-12 oz/gal (w/v) works well for electrostripping chromium from carbon steel substrates. The bath can be operated at ambient temperature or higher, at a current density of 0.25 - 1.0 amp/sq.in. The fumes evolved are toxic and must be evacuated and scrubbed. The bath starts out as a simple solution of caustic soda but acquires an increasing component of a hexavalent chromium compound as the metallic chromium is electrostripped from the workpieces. The spent solution is hazardous waste and must be properly disposed off.
Well you did ask.....
Or you could use a 30% soln of HCL and soak the parts in it (usually over night). - this will remove both hard and decorative chrome plating.
Both the above are for mild steel substrates.

.........does this mean that I have to wait for SWMBO to get out of the bath first?

Hi Cliff excellent answer as always except he wants to clean Brass. I would have thought Brass might fizz even faster than the chrome so leaving a shell of chrome and no brass? olewill

OK, Go for the first one then and watch the chrome come off - the brass will be OK until all the chrome is removed - quick polish and replate.
Better toake the fittings to a professional plating shop and let them do it.
