Dirt and grim worked past the seals somehow, and the seals were not elastic enough to close back around the gaps that were left. When your fork compresses it exausts air and when it extends it sucks it back in, this is not going to harm your fork, but other stuff is going to get into your fork and in the long term this can damage the internals (short term though don't fret).
The first thing to do would be to take the lowers off and "clean" the seals. Unfortunatly the seals may not show any sign of being "dirty" though, and this is not always sucessfull.
The 2nd step is to get new seals. There is a company called Enduro seals that makes seals for the Fox, they are supposedly better than stock. You could also order seals from fox. The third option is to order seals from a seal supplier. These are usually exactly the same as what comes in your fork stock, except instead of $30 bucks they are usually like $3 bucks (there's a huge markup on seals if you haven't noticed). The thing is that you have to have a store so you can bring the seal in, OR you have to know the OD/ID and height so you can order it online.
It's hard to say if it is the dust wipers or the oil-seals doing this though, I'd want to say that it's not the oil seals because if it was you should have some oil spewing about, but if air is going past the dust wipers it still has to get past/around the oil seals. Probably best to just replace both.
