I'm New to using a Meluna cup. I know it's made from TPE thermoplastic elastomer. I was concerned about washing this with dr bronners. This is what I use to wash my other cups with I do not know if it can indeed damage the Meluna cup because it's not silicone or anything. Anyone still or is using Dr Bronners to wash a Meluna cup? Any damage is this fine to use, don't wanna damage my cup.
