Another Electrolysis Question

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???

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.......

Rudi,

I use the Arm & Hammer Pure Baking Soda

For Baking, Cleaning & Deodorizing

Works for me :lol: :lol: :lol:

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?
