eto should smell neutral after washing. To remove wine or other lingering odours we recommend putting the red silicone ball seal and the black silicone glass seal parts ONLYon a baking tray and in your oven for 20 minutes on 200 degrees centigrade (that's 400 degrees Fahrenheit). They are pure food grade silicone so won’t melt.

Please don't put other parts of eto in the oven.
