Rust Treatment/Converters?

[josephr]

Working on an older Paramount PDG frame that was left in a basement...rust areas are mostly around the lug edges and bottle bosses. The rest of the bike looks just fine and is certainly has a lot of good rides in it. I've used a lime juice/baking soda mix along with a wire brush to take off the crusty rust...but still some areas are bare or need something...

my question -- has anyone ever used a rust treatment/converter on a frame? I've run steel wool over the rest of the bike and the paint looks cool in a old-crappy bike sort of way, so really just want to seal the spots I've scrubbed down. Suggestions?
Thanks!

Oxalic acid bath. Plenty of info out there.

If you're not going to be riding in the rain or live where condensation is a real problem, I'd do the oxalic acid (if it needs it) and then a couple of good coats of a quality paste wax.

Make sure though if you sweat and drip on the TT that you give it a wipe down after your ride.

Lime juice = acid
Baking soda = caustic
Add them together, you get a salt. I'm surprised that it did anything.

Citric and oxalic acids have a unique ability to remove rust (as stated above). I'd finish with a GOOD rinse, then frame saver treatment or some phosphate treatment to stop that corrosion.

Evapo Rust seems pretty highly reviewed on amazon.

Get some Bar Keeper's friend (oxalic acid powder), and use as directed.

Very stong black tea works real well.

Both work really well.

I used the NAPA stuff on my Univega beater. It is like clear paint that turns rust into some black stuff and seals it.
The frame is dark gray and for this it worked perfectly, almost not visible.
But again, this is my beater...

Meh. It has oxalic acid in it, but a lot of other things too. It's better for stainless pots than a true oxalic acid bath for a steel frame.

Thanks....I must've written my intro funny to get some of the other answers! This is exactly what I needed to know! :beer:

I have used POR brand metal etchers. They have changed the product but I still have metal ready.
