If you have extra nectar, just throw it in the fridge--it keeps for a week or more if you keep it cold. I have a bunch of 8 c. carafes that I'll be filling nonstop come the middle of July.
The mops are sold here wherever nectar feeders are sold. They've got a long wire handle on them with a foam mop on one end. You use them like a bottle brush. Remind me tomorrow and I'll post a picture.
