A great and natural way to clean memobottle is using vinegar solution (1 part vinegar and 4 parts water) or you can alternatively use bottle cleaning tablets from your local pharmacy. We recommend rinsing it out daily and topping it up with fresh water to avoid any build up.
If you have a long wire bristle brush this will also be useful as you can twist the wire as needed to reach the bottom and sides of the bottle.
The seal in the lid can also be removed if cleaning is required, and placed back in the lid to use as normal. You may need a tool to help leverage the seal from the lid base such as chopstick etc.
All bottles are also dishwasher friendly and can be placed alongside your dishes for an easy clean (not including metallic lid).
