First let me say that I'm a newbee both to the hobby and the forum... recently I purchased a piece where the blade has "greying" I think. There are splotches in several places on the blade. It appears to me due to the lack of any crossgraining left on the blade that it was over polished... thus the greying.
Can I do anything to help the blade or should I just keep it warm?

Welcome to the forum,

The blade greying is the bane to collectors worldwide and once established is virtually impossible to remove without heavy polishing which in most cases will ruin or make the blade less desirable than it was with the greying alone.
If you run your finger nail over the stained areas and can feel a top rust-like coating you could try taking a soft lead pencil and gently rubbing over the area which will lift the worse of it right off. It is then possible to use a metal polish like simichrome to reduce the stain even further but I would NOT use it on anything with crossgraining still evident.

Some collectors just wipe with acetone or alchohol ( not Gin & Tonic ) and then coat the blade with renwax, which is considered to be the best preserver of a natural blades finish.

Have a Gin & Tonic before you start to settle the nerves. Degens is 100% correct, just preserve what is still good and stop the corrosion. I have done the pencil method and it works good to remove the surface rust without damaging other areas of the blade.

Eric i love your avatar!!!

Paul,
It's the first dagger i bought when i started out in the hobby and thank's for selling it to me, it's the only dagger i have held onto since i started out. Even though i have had 30 plus SA's nothing compairs to it, i guess it's because it was my first minty dagger. Paul it is still in the same condition as it was when i bought it from you. For any new collector thinking of buying i can say Paul was very helpful when i had questions in the begining, Oh also he's the one responsible for my addiction. HeHehe

Paul sells great daggers, but to return to your question:

There is nothing you can do about blade "greying" that will not be easily visible and that will reduce the appeal, collectability, and value.

Dave, I must wholeheartedly concur with your assessment, except the removal of surface rust and specks with a #2 lead pencil rubbed across the spots. That's about all you can do and leave it after you wipe the lead shine off I think.
