Yeahhh, what sticks said!
I personally use a straw to scrape...I'm rather particular about cleaning though..
So, I clean at least once a week, but using the same straw, eventually the straw is full.
For my whip, I use 99% ISO and pour into tube, then I swirl it plugging both sides with my thumbs, think Jump Rope action. I usually do two back to back cleaning, then rinse with plenty of water.
Use a shop vac to dry immediately.
And everyday, I wipe my whip and mouthpiece with an alcohol prep pad, or simply dab some ISO on a paper towel and Sanitize the outer portion of whip and mouthpiece.
It's almost crazy how much dust/contaminant accumulates on the outside of the whip.
The first time I cleaned the outer wall of my whip with an ISO soaked paper towel, the filth I saw on the paper towel kinda grossed me out.
