Generally you can work dirt down to the bottom bracket, where it tends to go anyway. Then you want to get it out via the seat tube. The trick to that is to rotate the frame through the horizontal axis, turning it flat, then upside down so the dirt drops into the seat tube instead of back up the down tube.
Generally, what you hear isn't dirt from the outside but bits of flux or braze that were left over from the build. Once the loose stuff is gone, it's over for the life of the frame.

Dirt usually doesn't produce a rattle. Flux that has dislodged from the joints does. I would first consider a bath. Completely strip the frame and expose every vent hole possible. Soak wit the hottest water you can. Follow up with solvent as best you can. Dry out with heat of some low level. End with Frame Saver. Then consider sew up glue... Andy.

This is a grail frame so I would like to do the best thing possible even though there is no good way to know how bad it is and it seems like converter should also be used.

the C&V guys say that oxalic acid works well for this application. I have never done it myself. The damage is done, unless there is a cosmetic issue, I don't think anything you do inside the frame is going to have much on the remaining useful life of the frame. Framesaver will keep future damage from occurring, rust or no rust.
