Not one to like waste I thought...what could I use this this $4.50 pack of flosser sticks for?? And it came to me, I could use it to clean the four holes in my Lunette! It fits perfectly and scrubs them just like a proper pipe cleaner! I was previously using a bamboo BBQ stick (yes, the sort you poke meat onto). They are now part of my 'cup cleaning kit'. Ingenious!
Just thought I'd share! :)
