same problem here just the other day
.....I finally gave up and just did the following: removed all the junk I could from the adjustable cup side, then saturated the bearings with wd-40, and then stuck plastic shafted q-tips in and was able to clean the bearings that way. Then I just greased everything up, put it all back together, and so far, everything seems to be ok. It helped that my fingers are long and thin.....made it fairly easy to reach thru the bottom bracket shell and reach the bearings.
Good luck,
