Another Electrolysis Question

Postby Super A » Mon Sep 06, 2004 1:52 pm

Guys, I think I know the answer but I want to be sure: Will electrolysis eat away brazed areas on a part? I have a piece for which I am going to rig up a tank and "cook" it. I plan to use lye for the electrolyte so I can get the old paint off too. I am thinking it'll be ok but I want to make sure before I start!

I just did my axle tubes that are brass or bronze bushings BUT I did not use lye so I dont know if lye will affect it. Just use Arm & Hammer washing soda and it will also take off all the old paint on the part you are cleaning. Soap section in most markets.

Al:

Do not use lye :!: I read somewhere that you should never put lye in an electrolysis tank. Not sure if that is absolutely correct or not, but makes a little sense to me. Lye is caustic :!: It WILL burn your hands if you get it on your skin or if it gets in your eyes - Man IS THAT GONNA HURT :!:

There is no need to go to a caustic electrolyte. TSP WILL take off the old paint that is either a tad loose, chipped etc. It will not remove paint that is still well bonded.

After the part is dry, and in a well ventilated area use Easy-Off to clean those stubborn areas. Be easy with that stuff too as it is also caustic. Make sure you neutralize the area well also.

I have never tried TSP but when I use A&H washing soda it takes all the original paint off right down to bare metal whether well bonded or not. The old paint kinda hangs on like a shedding snake skin until I blast it with the water hose and the paint be all gone transplanted to my yard. :shock:

How much of the washing soda did you use per gallon of water?

I have used lye before to eat the varnish out of a gas tank and I don't like working with it. If A&H will work just as well I would rather use it.

I use 1 heaping tablespoon per gallon. I don't use TSP as it is a phosphate and too much of it is not a good thing to dispose of safely. Washing soda solves all the heart burn.

What do I need to look for in a power supply? I have a 10 amp charger and the only settings are 6 volt or 12 volt. Is that plenty or do I need (pardon the pun) more power???
If it doesn't move and it should, use WD-40. If it moves and shouldn't, use duct tape.

That will work just fine. I have the same and I use it on the 12-volt high amp setting.

TSP works ok, and so far a lot of wrinkled paint has peeled off with the hose. Unfortunately, I am limited to TSP as I have not been able to find Arm & Hammer Washing Soda yet. Still lookin though!

I do not dispose of my tank contents into a sanitary sewer, it goes directly on my lawn. Helps it too! That area was one of the few areas that didn't have too many weeds this year.......

I've used both Baking Soda and TSP Substitute (Phosphate Free), and both work well at removing everything, including all paint, grease, etc, and getting back to bare metal.

I looked in a half dozen stores around here, and could not find actual TSP anywhere, nor could I find washing or laundry soda (Saratoga, NY).

:twisted: Man, Soap is high in OK., I only pay $2.39 for the same size box at our local market here in northern CA. :)

Bruce:

Champlain place doesn't have it, but will check the other Sobey's. I am wondering what the difference would be between A&H Washing Soda and TSP?
