I keep getting colds and think I am constantly reinfecting myself from my Sigg water bottle. I've been cleaning it with dish soap and a baby bottle brush, but am not sure how clean it's actually getting since the neck of the bottle is very narrow and the bottle itself is opaque so it's not like I can see in it.
I'm thinking about either bleaching the bottle or boiling it in water to disinfect it and make sure it is totally clean. Does anyone know if doing either one of these things would ruin the bottle?
