Rust on edges?

post #1 of 9
Thread Starter 

I came back from SLC, landing on a night that's quite cold. The ski went back into my nice warm apartment. That was Tuesday.

 

Today, when I took the skis out, there's lots of rust on the edges. I knew the rust wasn't there when I pack them at SLC.

 

I've never had this happen in all the years I took my ski out west. I'm not sure what's causing all the rusting this time. I suppose there must be a lot of condensation on the ski when it went from 10 degree to 60 degree? 

 

What do I do with all the rust? Do I just go ahead and ski it off? Or do I need to sand it off first?

Simple polishing with diamonds stones should be enough. Can't be that deep in that short a time.

A Gummi Stone (any grit) will work like a magic eraser on that light surface rust.

If there's enough airflow to get moisture into the package (ski bag I assume) then there's enough airflow to get moisture out of the package before rusting is too advanced.

It is far more likely that there was moisture inside the package at the start point (SLC), that the moisture did not escape, and that the rusting accelerated when the temperature rose.

How good of a tuning setup do you have?  As others have said, diamond stones will clean it off and fast, but you'd want a pretty steady hand (or clamps, vices, i.e., tuning setup) as the penalty for a slip is rounded edges.

 

If you don't have that, then a gummi stone and some elbow grease will clean it off pretty fast as well.  Gummi stones come in varying hardnesses.  I use the blue one, but I don't think it really matters.  You would really have to try to do any real damage with a gummi stone.

Or just ski them.

Thanks! I'll try this, the simpliest approach first. :)

 

Whatever's left over, I'll see to it with a gummi stone.

 

The ski had only been skied a couple of days since the last tune. So I don't want to mess it up with a diamond stone just yet.

The rust after a few days is just color.  Ski it off.

 

Rust after many months of storage may have pitted the steel.  That requires a good tune.  Or, just ski them.  They'll probably feel the same except to an expert on ice.

I'm guessing that the "S" in SLC stands for salt right?:duck:

 

Anyway, it can also happen quicker when skiing man made snow with salt in the retaining ponds from road melt run off.  .  Takes a LONG time with exposure to warm and wet before it gets to be a serious issue.  Usually it will rub off, just skiing most of the time.  If it is more pronounced then a light tune will do.  Worst case a base grind and full tune will bring back all but terminal rust that is deeply pitted.  You may see some bleeding through the clear p-tex bases too.  Don't worry too much about that.  You're likely to get a core shot or wear out the ski before it actually compromises anything else.
