I would like to buy a fruit infuser water bottle. The previous ones we have had went mouldy very quickly (think a week) - not just the seals of the parts that come off but in the actual cylinder itself and we found it very difficult to clean - this happened despite daily washing up bowl cleaning of all the parts. Are some better than others from a cleaning perspective and also is there any that can be put in the dishwasher because physically cleaning them doesn’t seem to shift the stuff. I’ll be really use grateful if anyone could recommend something. Thank you.
