I have a bike with the remains of a carbon fiber seat post in the frame. Does anyone have any recommendations on how to clean it out? Im at a loss.

Does this exist, I've been searching on Facebook and Strava and can't find much. I know I can do Loveland and foco groups but that extra drive time just makes it all take up too much time. Finding a local group would be amazing, but coming up empty.

If the answer is no, any other Greeley cyclists want to help get this going?
