Rotary Evaporator Cleaning I am using a rotary evaporator ('rotovap') in my lab mainly with dichloromethane as a solvent.

Usually between experiments I clean the receiving and boiling flasks with a brush using soap and water and finally rinse with alcohol.
For the condenser I try to do the same, but it is next to impossible to brush the water serpentine.

I want to try and distil some coffee and tea for consumption, but I am afraid of any possible contaminants.

What is an efficient and safe method to clean the glassware?
There's no further need to comment on the coffee maker, but you might give the following cleaning method for the condenser and the rotation tube a try: 

Note that you might want to first check whether this is in accordance with local safety regulations! 


Take a small or medium-sized (max. 500 mL) 2-neck flask (NS29 socket connects to the rotavap, NS14.5 socket is for your thumb) and fill it with max. 250 mL acetone
Hook it up to the rotavap, support it with your hand
No spinning :D
Start the vacuum pump
Close the NS14.5 socket with your thumb
Watch the acetone starting to boil under reduce pressure 
Rapidly remove your thumb from from the socket and let the acetone "spit" all through the rotavap
