Why are water bottles hard to clean?
There are so many water bottles available offering various features to improve ‘performance’. Unfortunately, the cleanability is often not considered in the water bottle ‘performance’. Many bottles are designed to look great on the shop shelves but not after plenty of everyday use.
Some features that I have found ensure an easy clean water bottle are:
Simplicity
The simpler the item, the easier it is to clean. Think a glass compared to a bottle. I know which I would prefer to clean. Two good questions to ask yourself:
- Can those extra water bottle features be easily cleaned?
- Do those features improve the ‘performance’ of the water bottle for me?
Wide mouth
The wider the mouth of your water bottle the easier it is to get a brush and water into the corners of bottle.
An area where it is commonly difficult to clean is the shoulder of water bottles (where it tapers towards the mouth at the top).
The wider the mouth relative to the rest of the body the easier it is to clear this shoulder area. Think of a standard glass - the widest area is the mouth. A glass is often really easy to clean as there is no shoulder.
