-----How to clean & polish aluminum wheels
The "dust" that wears off of brakes and falls onto wheels is metallic, and the metal is very galvanically incompatible with aluminum and corrosive to it. The first line of defense therefore is to wash/scrub the dust off as often as practical before it causes corrosion. Once the aluminum has acquired very fine pitting from reaction with this dust it will lose its brightness and require polishing. Read on ...
Polishing Pitted Old Road Bike Rims
Q. I need to know where to start when polishing bicycle rims. I have a Medalist Series 2 Road bike from the 1970's. I have polished the back rim and removed all surface rust, it has come out great. However, I've got the front rim and it is terribly pitted, I was wondering, how should I proceed to grind it down to the metal and get almost as good a shine? The rim is original to the Supercycle Medalist Series 2 bike. Does anyone know what the factory had initially plated on it, or if it has been anodized underneath? It has been chromed and I know I have gotten through to the nickel plating (yellow tinge). Should I just polish it down to the metal with 80 sandpaper until it's there. Then proceed to finer grades? Where do I start for this extreme tarnishing and pitting. It's only about a 5 inch section of the rim, so I only need to remove that spot of pitting.

A. Hi , I would suggest taking it to a proper metal polisher .
They have high power polisher machines, and various mops and polishing compounds .
It wouldn't take too long and I doubt it would be too expensive
.
Your own method seems to work , but if you use sandpaper , you will probably leave scratches.
Hope this helps

Q. I have tried just about every spray cleaner that the local auto store sells. I have searched the internet and came up with these questions.
1. Items like Trailer Brite that contain acid are bad for wheels and cause damage.
Can it be used safely at all? I have embedded brake dust and some pitting on the wheel. I have found nothing to get it off.
2. If I was to use aluminum polish, and polish the wheel with a buffer, will that clean the wheel or just shine it. I just bought Eagle One Nevr-Dull

and it shines like no end, but did not clean it.

A. If you feel that something is embedded, BT, I think you should try to pressure wash it

eBay or

, or scrub it with a tampico scrub brush
⇦ on
eBay or
Amazon [affil link] , After washing, you can polish.
In truth, though, you don't polish out a pit; rather, you polish away any metal that is above the bottom of the pit. Obviously, this can mean substantial metal removal, which could be difficult to remove with so mild a polish as Nevr-dull. You may need power equipment and a buffing or polishing compound with a substantially larger grit size.
Good luck.

A. Your wheels are going to need something more aggressive than sprays, rubbing compound or little fuzzy balls on a hand drill. Depending on how pitted and dull they are will determine what you start with. Probably a polishing wheel with a fine emery base compound ⇦ on eBay or Amazon [affil link] about 220 grit. Following that with hard fast turning buffs using a brown tripoli buffing compound ⇦ on eBay or Amazon [affil link] and finishing with a soft cotton buff using a fine white chrome rouge ⇦ on eBay or Amazon [affil link] .

A. I have a set of 14 year old Hellcats that I have not polished in the last 4 years. The best thing to clean them up with is Mothers mag wheel polish and for the spots where you have pitting I have myself wet sanded that crap out with real fine grit then polished the wheel and they look damn near new.
Now the center caps are a different story -- don't think they are made of the same grade of material; they are a pain in the neck. Hopefully this helps -- good luck.

A. Okay rookies, I'm a 14 year old young man. I haven't found any chemical that is available to the public yet that cleans aluminum just by spray and rinse. I wish there were.
But here's your answer:
The only thing that works is MOTHERS, you can find this at any auto supply store in the car wash supply section. But, you really have to be dedicated like myself to polish with this solution. Best way to polish with Mothers is by hand. Yes by hand. You go through different layers of tarnish and in my case "brake dust".
If you use MOTHERS correctly, you make aluminum look like chrome. So when you're polishing away thinking you got the best shine out of it, think again, keep going. You'll continue seeing you cloth turn black, repeat and follow until the black is all gone. I know my writing isn't good but I hope this has helped you.
