If you try to do it mechanically, you'll end up cutting into the steel underneath and ruining the heads.

Electrolytic stripping in a tank of caustic solution is the method most professionals use, however it can be chemically stripped with many different acids as well (50% HCl or 20% Sodium Hydroxide will do it)- though it takes a solution much stronger than Coke to do so.
Disposal of the waste is a serious consideration, as it is real hazardous waste in every state and there are no personal disposal options. You must dispose of it professionally or risk huge fines.
If you are trying to get to the bare steel you will also have to remove the nickel. Much more difficult to do chemically - and not typically something a hobbyist can do.
This really is a job better left to the professional - both for the equipment needed and the disposal of the waste.

3:1 - H2O:H2O2
HCl concentrated and dilute
3:1 - HCl:H2O2
2:1 - FeCl:HCl
Cyantek CR-7s (Perchloric based) 7 min/micron (24A/s new)
1:1 - HCl:glycerine 12min/micron after depassivation
1:3 - [50gNaOH+100mlH2O]:[30g K3Fe(CN)6+100mlH2O] 1hr/micron
I chose to present the water and peroxide method as opposed to the other nasty ones.
Sorry if our experiences don't overlap and the techniques are different for the different fields. Not anything to get upset over.

Overall, it took me around 35 mins to finish the one head.
Check out the pics....

Here is what another GolfWRX member sent me. It makes sense, i just didnt try it
"looked in my book for metal etchants, and it says 3:1 water to H2O2 for a SLOW chrome etch. It doesn't give a rate so I assume it will take a little bit of time. I also says to heat solution to 50 degrees Celsius (~122 Fahrenheit). The household version of peroxide should work, just not as effectively as a purer grade.
If I were doing it I'd try it with an older club first though. As always be careful. Particularly if you don't have any experience doing processes like this."

It looks great at first, but it WILL wear off with in no time.

Did you reapply the perma blue? Or did you let it fade? Can you provide any pics?
