Clean what you can reach with a rag. For the seat tube, make a small wad, and push it through with a stick. Down tube and chain stays tie a string to a corner (securely) push the rag up the tube with a coat hanger, then pull it back with the string.
When you've gotten the worst out, spray some WD-40, or a light solvent/oil mix (10:1) all around and let it drain to the BB overnight and wipe out the residue. Odds are that over time a bit more grit may fall down from places you didn't reach, but unless you use a loose ball bottom bracket withour a plastic liner it won't matter.
