is there a quick easy way to clean these things? I got some, out of 3, one still working great, the other two, are working, but no where near as well as one of them. 2 are usuable on 3.7v battery but at 3.2 volt are useless. all used the same amount, all used with same liquid. I tred cleaning one by rinsing in hot water and then dry burn, it seems to be better, is that the best way?
I think part of the problem is that liquid is always running down the center when filling them because you never know when they are filled, but I can't use the clear ones because they just fall apart.
