same here,
mocha lady, lips do stick together and like to stay stuck.
i don't really try to fix it up (i'm pretty sure when i go to use it and run some water through it and lube it up it goes back to normal)
it might leave marks if you're scratching it with your finger nails to seperate the stuck parts?
yeah, the corn starch will make it feel nice (just like it was out of the box), even though i'm yet to try powdering it.
i saw a little squirty bottle (maybe 150ml) of 100% isopropyl alcohol at the hardware store (in the turps and cleaning section) for about AU$10... would this be alright to use for cleaning? 100%!?!?
