Getting rid of rust?

[Purple_Pride]

I tried searching this site and didn't find a post dedicated to rust removal, so I'll ask the question here:
What are the best methods for getting rust off of:
Chrome, frames for repaint, engines to clean appearance and internals.
What tools, chemicals, processes work best?

Just one thread. But hopefully this one will spark some more interest.

I like Naval Jelly for removing light rust...been using it for about 30 years.

Brush it on...hose it off...dry with an air gun or hairdryer...

We have one of these at work. I just powerwash a frame real good and after about 20 minutes in here its ready for Powdercoating

Try brasso that stuff can remove car paint

Also keep in mind that Local sandblasting companies will blast a frame and forks for super cheap.

Theres a local company here in town that will sandblast it for $50 as long as its tore down and ready to go.

Hey Purple, Blasting is the easiest way to go. Be real careful about what
type of abrasive the people doing the blasting use. Some abrasives like black
beauty etc. will leave your frame with the texture of 80 grit sandpaper. For a
smooth blasted finish have them use 50 micron glass beads. Does a beautiful
job. Ogygopsis

"Rust never sleeps" and you can't get it all unless you remove it ALL by blasting.

Before.

After.

steel wool works wonders on chrome

 

[minibikeguytlc]

Yeah it does, did it on my El Burro handle-bars. Not permanent though...

Hey GTO
Those rims came out great! See some pretty good customizing there. Nice work! Is it powder coating or paint?

Thanks, the finish was standard spray cans which is easy to touch up if need be. :thumbsup: Doing the same on the frames but might do a little air brush on a few for bling. :thumbsup:

I also prefer medai blasting, usually with ~60 grit aluminum oxide(sand color) if a dull finish isn't a problem. I have some glass bead of unknown size and whatever it is, it makes an awesome satin finish! Silicon carbide(gray color) works well for a dull finish as well.

Just make sure your stuff doesn't get shot peened or blasted.....I have some Mopar steel wheels that were shot blasted and it's a nasty finish that spray paint doesn't cover very well. It took a lot of epoxy paint to fill the roughness.

Best way to remove rust

Hi, everyone! I'm new to the site. I came to this site in search of finding a Mini bike like my old childhood mini bike. It was a scamp but model is unknown. If anyone has a catalog of scamp bikes with pics I would love to see them. I really would like to narrow my search. I know it wasn't the road version.
Anyway I want to restore one for my 1 year old son. I figure by the time I'm done restoring he will be perfect to ride it. Any help would be great!

P.S - I restore old BMX bikes from 70's and 80's. Whenever I remove rust on chrome or metal I soak the part in oxalic acid (Wood bleach) Below are picks of before and after's. Nothing works better!

Thanks for your help.

I have not tried it yet, but electrolytic rust removal is supposed to work very well.

Yeah I have seen that at the part stores like Autozone. They also have rust converters which converts the rust into something like black oxide....I have some, just havent used it yet!

Are you talking about the two part bleach? I used to use it all the time on wood.

Both won't do anything really rusty and won't help you with pitting the converter is nothing more than a water base with acid in it and it doesn't work well for anything major and does nothing for the weather.

 

[justjuiceit]

But cant you apply primer and paint to the oxide layer?

 

[GTO]

Yes but your better off getting rid of the rust for good. That stuff is made for a quicky fix but rust never sleeps and I remember using some on stuff outside then painting it,,, the rust cam back from "down under".:thumbsup:
