There's been many ways written about how to remove rust from chrome, steel wool, etc. For those who haven't tried this, do yourself a favor. Easily removes rust from pitted chrome. Doesn't take much elbow grease to boot. You may find it in a boat shop, otherwise you'd have to order it like I did. http://www.collinite.com/automotive-wax/liquid-metal-wax/
The stuff mentioned may be better but I have never had a problem with noticable scratches when using wet soap pads (SOS pads) but usually the stuff I use em on is pretty bad and can only look better. Ive used them on old wheels and bumpers etc. for years and have had pretty good luck.
SOS pad, well lubricated and, then cleaned and followed by, Turtle Wax Chrome Polish. Has been working since I was a little puppy in 1957 polishing the chrome fenders on my used Schwinn I bought for 50 cents from Bobby Abernathy.
Im an old SOS pad Turtle wax polish myself. But Collinite products are just the best. Use them all the time on the Boat. Hard work but season lasting results. Have to try the stuff sometime. Also as mentioned for fine work Blitz and the like.
Eagle one also has a silver can with oil soaked wool cant remeber the name right now but i have always had good luck with it
Copper scrubbing pads (they don't scratch) and Pledge. Follow up with Simichrome, Flitz, Autosol or your favorite polish.
Solution of molasses and water, about 1:9 ratio will remove the rust from anything and not harm the metal at all. Takes a couple weeks of soaking though, followed by power washing. Watch this. Works good. http://www.youtube.com/watch?v=KZCFcxf5IBw
I used to make a set of rusty chrome wheels look pretty damned good by wiping Navy Jelly on them, cleaning them off and then painting them with chrome paint; but before the paint gets tacky wipe it off lightly. It will wipe off off the good chrome but stays on the bare metal spots. You'd be really suprised at what you can save. It won't pass a show judge but is perfectly streetable.
Deluded CLR with water and .000 or .0000 depending on how heavy or light the rust your cleaning. Follow with your favorite metal polish.
i did this a while back,NO elbow grease at all! http://www.jalopyjournal.com/forum/showthread.php?t=693523
I've been using this stuff for over 20 years - little bit of water and a toothbrush and it does wonders. Basically liquifies the rust and you wash it off. Wal-Mart and most grocery stores around here sell it.
Lay down a nice film of lube (such as WD40) and then scrape with a cheap stainless steel bladed pocket knife. Follow up with some chrome polish.
I just bought a set of old cragars for cheap. My question is how far is "too far gone"? I mean the lips are good, just rusty. When is the point when you can't mount a tire anymore?? Thanks
