Another thing you can do is add a tidbit of H202 (hydrogen peroxide) to the luke warm water youre soaking them in. And don't immediately toss out the ones that dont pop/sink in 24hours either. Sometimes if you give 'em a little tap they'll sink.
The stable warmth is important, too. Somewhere like, say, the top of your refrigerator is a good place.
Good luck
