The Solo has been designed to be washed either by hand or in the dishwasher. In the lid you can untwist the submerger to wash both parts better.
If you travel with a Solo full of water you have to ensure that you keep up upright as water could leak out from the valve.
Once the sterilized equipment is taken out of the fluid and put in a baby changing bag for example, our solution is to use the Solo. If it is only one baby bottle, as long as the cap is clean it needs to be put on to protect the sterilised teat. It is a great way to keep sterilised items clean.
