Removing oxidation from NOS radiator core
I posed this same question on a thread several years ago but I cannot locate it in the archives and my fading memory cannot recall all of the great suggestions given to me. I have a NOS radiator core, still in the box, that is covered with fine film of oxidation on the brass. I need good solution for removing the oxidation before painting. Looking for information to refresh my memory.
Also, what is the correct nomenclature for the felt covered glass channel pieces that fit in the rear edge of the front doors that the glass slides back into when "cracking" the window for ventilation. We call them "Bat wings" around here, but that is not a Ford term. Much appreciation from an old man with a bad case of CRS. Lawson

I would mix up a few gallons of water with white vinegar, pour it in, gently shake it for about 5 min. and then pour it out and rinse with clean fresh water. Repeat as needed.

Re: Removing oxidation from NOS radiator core
What ratio of vinegar to water? Do you need to neuteralize the vinegar in any way?

Lawson....Just to be clear, you're talking about this oxidation being on the OUTSIDE of the radiator, correct? DD |

Re: Removing oxidation from NOS radiator core
Lawson, I would add 1 cup vinegar to 4 gal water. Soak and rinse, rinse, rinse till it's nice and clean and you don't taste the vinegar.

Re: Removing oxidation from NOS radiator core
Get a plastic cement mixing tub from Lowe’s the big one. Then stop be supermarket & get some quarts of Coke. Enough to cover core. Let soak a few hours then rinse off. Good luck.

Re: Removing oxidation from NOS radiator core
When I worked at a radiator shop in the 70’s, we would use Muratic acid to clean the inside of the radiators before I painted them. It got them shiny as new on the inside, If any got on the outside it would do the same.
Just don’t leave them more than a few seconds if using pure acid. A watered down batch would work better I think. |

Re: Removing oxidation from NOS radiator core
... and for anyone with an aluminum radiator, don't do this. You will end up with a nice gray tank.

Re: Removing oxidation from NOS radiator core
An old boss of mine took his radiator out of the tractor and decided to flush it with muriatic acid once. Filled it up and left overnight, next morning had a clean leaky radiator and a hole in the concrete that was under it.

Re: Removing oxidation from NOS radiator core
Also a phosphoric acid diluted with water will work great. That was the reason for using coke in the post above. You can find some in the paint department of any Home Depot. Also great for general de-rusting. Light oxidation is ok to leave, just shoot it with a light coat of some black lacquer. The residue left behind (phosphoric coating) will actually prevent further oxidation.

Re: Removing oxidation from NOS radiator core
That's all I can see. May be on inside of tubes as well. I'm figuring to soak the whole thing to get both inside and outside surfaces.

Re: Removing oxidation from NOS radiator core
Washing soda, aka sodium carbonate(or soda ash), is a natural cleaner and a powerful water softener. It has a very high ph, 11, so be careful.
