Alcoa forged aluminum wheels

2018 view with upgraded wheels to Alcoa forged aluminum. Tried to rotate them front to back as recommended in the mb manual. opposite sides are very dirty and rusty. Could not clean them so put wheels back in their original configuration by rotating. Front and back. Side to side. Question is how to remove rust and dark residue. Tried the following with little effect: Black Magic aluminum wheel cleaner, Black Magic intense all wheel cleaner. mothers mag and aluminum polish and finally scrubbed with eagle one original never-dull. Elbow grease does not get me to where I want to be. Any suggestions would be most appreciated.

Sorry for your troubles. Operator Manual notwithstanding, it is not cost effective to rotate the tires on a dually. You run them in place until damaged or worn out and replace them.

A real PITA if you have 4/6 Aluminum Rims only two of which fit one axle.

Just keep the inflated no higher than the recommendation on the door placard (61 psi); align if necessary; inspect frequently and drive on....

Enjoy the ride!

gary,
Well, as has been stated, while the owners manual is the bible for some and, for about 98% of the time, it's pretty good to follow, rotating tires on just about 99.999999% of the motorhomes out there, is really not warranted or, in the same amount of percentage, is pretty tough to do so, based on logistics.

So, with all that jargon stated, you've found that wheels can get pretty ugly in certain situations. Now, I've been polishing aluminum since Christ was a pup. Depending on what stage the aluminum is in when the project is started, there can be multiple stages of progress for different results. For instance, as stated, I keep my wheels etc. on my bike, motorhome etc. in top shine. But, for some odd reason, I neglected my rear wheel on my motorcycle for quite some time 'cause it's one of those things that, "out of site, out of mind" things.

So, I had to replace a tire on the bike and the brakes so, off the wheel came. WOW, that wheel was ugly. Using standard aluminum polish was totally useless. So, I dove straight into the project with some 400 grit wet/dry sand paper. The trick here is, LOTS OF WATER, to keep the particles flowing away from your work. Once you've cleaned the wheels with that 400 grit, it's time to move up to 600 or possibly 800 grit. You can do that process 'till the scratches from the 400 grit are all removed.

Then, the same results are seen with each grit. Finally, you move to around 1000 or 1200 grit. At that time, the wheels actually begin to shine. Once the entire wheel's been done with the 1000 or 1200, it's time to break out the drill motor with a buffing cone or wheel on it, using a brown rouge. You'll see that wheel start to gleem.

Once that's done, change buffing cones or wheels, which ever you're using and, using the same drill motor, apply MOTHER'S. You will not get it any shinier than with the use of Mothers. Yep, it's a bit of work but, when you're done, unless you drive your motorhome through the waves at the beach (think SALT), they will stay like that for months and months, without touching them. Good luck.
Scott

Take it (RV) to a truck stop or truck wash of good size tell them to acid wash the wheels, most big truck washes have people who will polish and buff them out. A lot easier and faster, they have the right equipment and do it all the time.

If these are the Dura-Bright Alcoa wheels they have a thin anodized coating that is destroyed by trying to polish the surface. Go to the Alcoa web site and get their instructions for how to care for the wheels. The fronts are polished on one side and the rear outer are polished on the other side. It is not possible to rotate them per the MB manual without dismounting the tires and remounting them. You can swap left and right sides but that is about the only way to do any rotation without dismounting the tires. As others have said watch the wear, keep it aligned and drive it.
