My Baby Bullet leaked through the base and now the base is gunky. It's usable but i have to carefully lift the top container out slowly because the base continues to spin and spin for a while. I believe it's because the leaks that have occurred have made everything very gunky and sticky. I could have sworn one of the times it leaked, it's as if the thing loosened ITSELF during use...weird. How do i clean that gunk out. I've tried dried brushes etc but this stuff is the consistency of mushed raisin.
