I really don't want to use a peroxide or antibacterial solution on it because I've heard (and believe) that it can damage the silicone and make it more susceptible to bacteria.
I've read on this board that people put them in the sun, so my question is...how? Leaving it outside isn't really an option because I have a rascally dog who would surely eat it.
Should I put it on a windowsill?
How do you ladies "sun" your cup?
