Merry Christmas Chewy Pals! Chewy 2 is now my sole grinder and things have never been better. I love this thing. I have found a couple of spots that gum-up after a few days and before a full cleaning. I clean these areas every few days with a little coconut oil or ISO. I am not making any claims that Chewy needs cleaning, (see @Vitolo comment above), however, if you can see friction areas caused by resin buildup it may help to remove it more frequently. I use a little coconut oil on a q-tip or some ISO on a q-tip.
