If you regularly use your Corkcicle with Tea, Coffee, or Wine, you may begin to see some discoloration/staining on the stainless steel interior. We suggest using baking soda and lemon juice, or household vinegar to clean your Corkcicle product naturally.
For heavy-duty staining, our team suggests using Bottle Bright to rid of any interior stains. Corkcicle is unaffiliated with Bottle Bright, but it’s a common product found in our office! Bottle Bright is natural, safe, non-toxic, biodegradable & chlorine-free.
