After a few months continual use all of my protein shakers just develop the most foul stink smell, I am a bit of a clean freak and this bugs the shit out of me.
I have arrived at a solution and I thought I would share it. Put some vinegar into your tubs and soak them over night, rinse and clean out with soapy water the next day and WHAM neutral smell again.
Thanks for your info but you’d be better off not using plastic to drink from. It has pores and glass doesn’t. In other words, you can’t ever get it clean because of it’s molecular structure.Use glass instead. Not trying to be argumentative but plastic is bad news all around.
Does anybody make a glass shaker cup?
