Help! I'm on day three and I use a USN Tornado shaker to mix my shakes and well I wash it religiously, constantly, with hot water and washing up liquid but it still smells a bit... funky. Has anyone got any household tips to stop it smelling like mank? I'm a wuss for flavours so I'm only having choc and choc mint shakes. I find the minty smell hides the nasty niff quite well but the normal choc shake just smells a bit mouldy.
