Put them in a dilute muriatic acid for a while. I don't know if there are
fume problems.

> Muriatic acid will remove plating from bolts, threaded rod, etc.  Just place 
the hardware in a plastic bucket and pour it on.  It will fume and smoke for a 
short time and the plating will be gone.  Hundreds can be done in the time it 
would take to do 1 part in the forge.  Of course, this should be done outside.  
The acid can be poured back into its jug and the parts flushed with fresh water.
This process will also remove rust but if the parts are not dried immediately, 
it will also cause them to rust.  Muriatic acid is available in any hardware 
store as it is used primarily for cleaning brick and stone.  It's cheap, about 
$3.50 a gallon and a gallon can last several years.  Like most acids, 
temperature is a factor in the speed of operation.  The warmer the faster.  Of 
course, all of the safety proceedures for acids should be observed with this 
acid as with any other.  Give me a holler if I can be of any further assistance.

To All,
To remove plating from bolts and threaded rod, use muriatic acid. The
reaction is fast so it wont take long at all. Rinse well with water,
neutralize the acid with sodium bicabonate and oil if you are not going to do
any thing with them right away. Do not rinse them in the slack tub. The acid
will change the quenching properties of the water.

Dear George,

   A solution of water and muratic acid will remove zinc plating on nuts,bolts, rods etc. 2 parts water to 1 part acid. Use in well ventilated area. Take roughly 10 to 15 minutes to remove plating.
