I've kept a water bottle that I use daily next to my bed. I've kept it there for two years without washing it once.
Is there a reason why it has not been washed?
It's my bottle, and I don't think it's a problem.
Washing a water bottle can seem silly, because it's only has water in it. However, keep in mind that you're putting germs on it each time you drink from it and those germs can propagate which can be risky for your wellbeing. Wash your water bottle every day to keep it clean and keep yourself healthy.
I am not worried about being healthy. I take my vitamins you douche. Where can i get a more intelligent advice giver.
I am not sure where to get one of those, but I think that you should wash the one that you have more often. Washing dishes regularly is expected to keep the dishes clean.
