Whether you’re going to sell your bike, or you just want to make it a look a year newer, getting rid of the black marks on your bike’s aluminum frame will help accomplish either.
First thing to do is wash your bike. Any dirt or mud stuck on it will make the process more difficult. Now grab some steel wool that is more on the fine side. You can either spray a little water or WD40 on the frame; both work about the same. After spraying the area of the frame you want to clean the boot marks off of, scrub it with the steel wool. I usually take a few passes, spraying it with the hose every time, just to keep it clean and see where the black marks still are.
After I get done with one side I spray it down with the hose again and move on to the other side. Once all said and done I wash the bike with soap and water so that there’s no residual metal/WD40/boot material left on the bike.
There you have it… a pretty much new looking bike again! Well, it may just be the frame, but it definitely gives the bike a “newer feel.”
Now when you Haul Your Bike to the track you can impress your friends with your fresh aluminum frame. They may be so envious that you could make a couple bucks from doing it to their bikes too!
If you don’t want to have to clean the marks off every few rides, I would suggest you look into getting some Frame Guards. They’re pretty cheap, and protect your frame from boots. Good luck, and stay safe riding!
