You just cant service rubber sealed BB's unless you remove the seals. Use an Exacto knife. There's a learning curve to their removal. But they just have to be opened up to flush solvent and debris and relube with grease. No short cuts here at all. Properly done they will feel like new and be given a second life. To soak them with the seals 'On' is an absolute waste of time. Don't even bother. Will do more harm than any good.I tried finding videos on this and they are YEARS old and most were using WD40. What is suitable solvent? Do you remove the seals? I saw a few that did and a few that didn't. Also what is typically used to oil or grease the bearing afterwards?
With seals left On, better off just wiping off the outside and place a drop of oil onto the BB and hope that penetrates enough to keep the BB going a bit longer. Then just have a spare set of BB's to replace more frequently.
edit: I use a automotive brake solvent to clean bearings. Some say its too strong. Citrus cleaner is an ECO friendly solution also. But always wear gloves if feel the need. Brake solvent is much quicker and evaporates quick leaving no resido. Bearing needs to be flushed of what ever solvent you choose prior to lubing with grease or oil. Fill BB with 1/3 grease at most. One or 2 drops of oil if that is your choice. Spin them by hand and examine results. (Never spin a dry unlubed BB fast, immediate wear results to the balls and cage when dry). Then replace rubber seals last.
