If your water is not having any problem while you are willing to clean it then you can use the extreme procedure of cleaning. You can use the baking soda and vinegar solution and then try to disinfect your water bottle by that. This can make sure that all the germs are killed which were present in the water bottle and you can drink the water for a long time without any danger of illness. You should remember that you can do the same procedure with the water bottle which can be used multiple Times. Reusable plain drinking bottles are cleaned in this same way so you can do the same procedure for yourself.
We all are familiar that if we are going to drink the water in the plain glass water bottles then not only it will be very tasty to drink but also the glass water bottle is very good to look at. Compared to that the stainless steel can give you the long life but it will not be as healthy as the glass water bottle.
