Rust Removal

[ClubChapin]

I'm trying to restore 3 SS Performers.

All three have some rust inside the square tubes. 



Is there a good way to remove this rust and then protect the inside of the tubes?

Poking around, it looks like an Oxalic Acid bath is popular is the bicycle community to de-rust the inside of bicycle tubes. Phosphoric acid, Citric Acid and Vinegar baths are other chemical means I've found for removing rust.

Does anyone here have any experience with acid baths and removing rust, or experience removing rust from the inside of SS Perf frame tubes?  Ideally, the paint on the outside of the frames can be preserved.  It is in pretty good shape.

Thanks.

I'm not finding the thread I remember about this specifically.......
@pbe gummi bear may remember where.......
He has a long involved fix up thread, but a lot of the pictures have been moved so I'm not sure if it was the right write-up?

Citric Acid and / or Vinegar bath seems like it would be enough, with some manner of preserving afterwards.....

You can use a rust converter, naval jelly, or other rust treatment. It would be best to strip out all that rust though using a string and brush that can go internally. Personally I just shot some spray paint into there to help lee the rust at bay. There's almost a product called frame saver that the bike guys use to coat their tube id's to keep them from rusting. If you can find a trough, a vinegar soak is cheap and strips rust. I just soaked some tools this week and it worked like a charm.

has anyone ever used butcher block oil to keep rust at bay  after the rust has been removed  ///// like on a older kettle that you don`t want to paint to keep it more original

What about using the brush/string method, then following it up with a paint on rust paint, like Por-15 or some rustoleum product?  Would that stop the rust?

Any suggestions of a vessel that I could use to soak a SS Perf Frame, I think 43" x 25" (largest frame member)?

wading pool, bathtub, plastic bag of sufficient size

POR-15 eats rust & assimilates it just like the BORG.....that would certainly work......

Gutter trough or a piece of heavy rubber pipe cut apart......depends on how many times you might do this as to how much to spend on something.....
Personally, I got good @ dumpster diving for things like that.....

Thanks.  Is POR-15 something I copuld simply pour inside the tube and coat all sides?  That might be the best and easiest solution.  Or, is it a 2 step process?

Rust and metal work is all new to me.

Use this stuff.  It will not harm the paint.

If your parts are flat you can make a box out of 4x4's and then drape heavy black plastic over them to make a shallow pool.

So, I think the reality is that I am not going to soak the frame member to remove rust.  It is going to be too much effort and mess for me.

I need to find an easier solution.  I'd like to get a couple of these put back together by the end of the month.

Is there a paint (rust oleum, por-15, frame saver, or other) or coating I can spray or pour in the frame tubes that will stop existing rust and prevent future rust?

you wouldn't need to soak for the inside of the tube, just spray the evaporust in liberally with a spray bottle and then seal the ends for a day. hose it out, dry it out, then spray your rustoleum inside.

I use por 15 on my Jeeps.  drop a brush through it to get rid of any scale then pour the POR 15 in... it will convert any surface rust to "Not Rust" and keep a protective coating.  Let dry and reassemble.

Wouldn't hosing it out introduce water to bare metal and begin the corrosion process anew?

I think I'm leaning towards this approach.


Is this the right one?
