Yeah, I just flushed a Tiagra brifter that had been contaminated with sand... Used a whole (small 155g) can of WD-40 and a lot of running water, finished with an ounce of Triflow. Got most of the sand out, but not all. It seems to be working fine now. Of course, the downside of flushing a brifter is that it removes the factory grease, and now that it's lubricated with the light oil that is Triflow, I figure I'll need to add some once in a while since it doesn't have the staying power of factory grease.

I figure that having sand in the works of the brifter cannot be good in the long term. The insides will probably get ground up a lot quicker...

Of course, if you choose to do the flushing, you'll need to remove the brifters from the bike and then remove the hoods (easy). Still, that's quite a bit of work. Ah well, I guess the lesson here is to avoid getting sand in the brifters in the first place! Me, they were already contaminated when I got them.
