im thinking back to see if i can count how many times i bought stripper in a can. more than i can count, if this stuff works, ill owe you one.
 
Just so long as you are not trying to strip paint off wood, lye will eat the wood pretty readily.

You probably already know that, but I figure it would be good to post for anyone else who might not.
 
I just order some Sodium Hydroxide to try. I have some scrap that has gold under the solder mask. If it works on what I have I'll use it on all the parts that needs it and more.

Be VERY careful when handling sodium hydroxide. The slightest splash in the eye will pretty much guarantee you'll lose sight in that eye. Wear a full face shield if you can.

WARNING!!

I have been doing some research on the electrolysis of sodium chloride solution and the method shown in the video will NOT produce sodium hydroxide at the cathode, at least not for more than a fraction of a second before it and the chlorine produced at the anode combine to make sodium hypochlorite.

However, this process will, if enough current is applied and the solution temperature goes over 50° Celsius, produce sodium chlorate (NaClO-3), instead of sodium hypochlorite, and this compound can be very risky to have around as it is a powerful oxidiser.

In order to make sodium hydroxide, the cathode and anode must be separated by a membrane. I do not know where the author got the idea that placing a piece of zinc at the bottom of the jar will take the place of a membrane.

Another Youtube "expert". There should be a season on them.
 
One of the old methods to make sodium hydroxide was to have a mercury cathode in a concentrated salt brine bath, mercury will amalgum with sodium when a current is applied, this is then pumped into water, water reacts with the sodium to produce sodium hydroxide and hydrogen, the mercury is recycled back into the electrolysis brine bath and the cycle repeated, at the anode, chlorine gas is evolved.

Not something you want to do at home.
