Pitting on front fork?

I'm still recovering from two torn ligaments in my ankle (completely unrelated to riding) and I noticed that my front fork has what can only be described as pitting all over it. I've tried cleaner and it doesn't take it off. I'm thinking I might need to up my game. Any suggestions on how to clean these up?

If it's actual pitting you really cant remove it. Is it on the upper part of the fork that passes through the seal? If so it will eventually tear up the oil seal.

I agree. I had this when I first got my bike. Rode it until it chewed up the fork seals. Ended up having to replace both tubes. Not the cheapest.

If you are talking about the lower part of your forks ,aka sliders.You can get rid of the pitting .

The lower legs are clear coated from the factor and buge ,gravel and other debris nicks it and then the aluminum underneath starts to oxidize.It is a lot of work but you can sand off the clear and polish the lower legs back to a chrome like finish,and clear them again or just clean and shine them monthly.

But if it is the chrome upper leg you just have to live with it till it starts leaking and replace them.

Might be some help here.

I remember capHabs thread on cleaning and polishing the aluminum fork lowers.
Started with wet and dry sandpaper. Turned out really well.

Just read a thread about sanding gravel dings and high points off the travel portion of the chrome slider tubes using 1" wide strips of 200 grit sandpaper. Work the strips back and forth around the tubes, and up and down to create a light 45* cross hatch pattern. Said he did it ~30 times on his bike and rode 117k miles w/o tearing his fork seals up. The light sctatches are somewhat noticeable, but he only sanded down low where the tubes entered the lower slider unit.

200 grit? really, that's pretty rough. I would think it would leave all kinds of scratches.
I'd maybe want to start with a higher grit. But that's just me.

I wet out oooo steel wool with chrome cleaner and rub the area out, let it dry, and then use a polishing cloth.

I wondered about that too, but 200 was what he wrote.

Maybe he missed a "0", 2000 grit. Like what you would use to wet sand a paint job!
