wet aluminum foil with water and rub rust....works the same way....tin foil is harder then rust but softer then the steel and chrome (get for bicycle rust too).
@5Rickykx125 yeah it works on just about anything. If you do it to your pipe you should also go pick up PJ1 High Temp spray paint so that you can paint it black since the steel wool will remove a lot of the paint.
@bauxitus haha agreed! if you're able to find it, pick up Bel-Ray 6 in 1 spray too, it's AMAZING! Cleans plastics, removes and protects from rust, lubricates levers and cables and tons of other stuff. and you're welcome! I would get your rust spots covered up later on but this is a good temporary fix for stopping rust from spreading
@mxz440skidoo true, but the frame a lot of times rusts because it's lost it's powdercoating. My more permanent solution is to do this, cover it with a layer of clear coat, let that dry, then put grip sheets over the area. Basically you cover the front of all 4 a-arms in grip tape and they won't get scratched up but this is the easiest way to maintain a non-rusty frame on any given day.
Don't worry I'm 15 too. I do not know how to powder coat at all. Most the time you have to take it somewhere to have it done by a shop. I do know that you need a special gun and powder coat paint but there aren't any guides on how to do it online.
WD-40 ... not so good. Unless you make sure to remove it all when you're done. WD-40 promotes rust over time. Spray two similar steel surfaces, one with WD-40, the other with less-fancy oil. Let them sit outside for a month and see which one rusts first ... WD-40 displaces moisture (a useful trait) by absorbing it (not so good.)
