I have my fridge turned right down... when i put any type of can in to it, they go flat. I have had flat lager but thought it was a bad batch bit now my cans of coke are flat too?? The fridge can't be too cold as I only have it on number 2
Are you consuming the drinks straight from the can or pouring them into a glass? If you're using a glass it could be a competely unrelated problem such as changing the brand of washing-up liquid you use. Many detergents leave traces on the glass which can result in drinks going flat. (Beer glasses should never be washed in ordinary household washing-up liquid. Either use a specialist product or simply use clean, very hot water).
