Ahren says in the last paragraph of this link that dust brushes are "coming soon". CNCRouterParts
If you can stand to wait, I'd see what he comes up with first.
I have adequate protection of my X-axis but my Y-axis carriages are getting gummed up regularly. Has anyone come up with a cost effective way to protect their CNCRouterParts carriages? I have looked at the rubber bellows at McMaster and wow that is an expensive route…
Some people use tooth brushes. Cut the head off and epoxy it to the carriage in some manner. A good dust shoe and dust collection system controls almost all of it though.
Never used the carriages, but you might want to try a thin brass scraper, bent to apply pressure to the rail to scrape dust away. The brass is soft, and will wear to the rail. Should work much better than a brush.
I've seen this used on large vertical panel saws.

As I am waiting on my stuff from Nate, I am been thinking about this, I plan on building a bellow that will cover the entire rail or do a wiper with some Buna-N rubber.
Right now I am leaning towards the bellow however, the wiper will be so much easier and less time.
I used angle mounted to the extrusion slot above the carriage and it keeps my rails chip free i will post some pics if you would llike.
I just started playing with the idea of changing my design from supported linear rails on my x to these blocks. The problem of dirt and dust was my only concern and I just started worrying about this very topic tonight. Pics of how you have done it would be great.
On a side note, how are the bearings compared to supported linear rail. I like the idea of using them better because it simplifies my design significantly.
here is what i did i thought about brushes but this seemed simpler and more effective
