After a major cleaning yesterday I headed out to find that I had an annoying squeak coming from the right side whenever I pedal. It seems to happen on the down stroke, but not when i'm grinding out of the saddle. I can make it happen at a stop and apply pressure to the right side. Not sure if it's the crank or pedal... then i realize it's the cleat.

When I get home I clean everything and it still squeaks. I apply some oil.. still squeaks. Finally I apply a small amount of grease and it's gone.

I'm just concerned that the grease will attract dirt and grime.

There must be something better... suggestions?
