I was wondering if anybody who has the superpet chew-proof glass water bottle knew if the glass part is dishwasher safe. I assume it is but it's always good to double check.
I remove the metal section that covers the white plastic and that cancels out the rusting issue, at least it has for me. I do still prefer the lixit bottles over the superpet, but I sometimes get them in with rescues so I just do the needed adjustments.
As for them being dishwasher safe, yes, the glass is. I wouldn't recommend putting the nozzle in there. Super hot water and bleach break down rubber, and will also make the metal rust faster.
