Keep a fridge smelling fresh ? Apart from those commercial things ? I have a relatively new fridge and clean it regularily, but sometimes some food Mr. Sam puts in there, his sauces and so on, do pong a bit. Yesterday I took everything out, could'nt really find the culprit, but chucked a few things out anyway and gave it a good wash, but there is still a faint smell .
Don't store anything smelly in polythene containers at all! Believe it or not, polythene is slightly porous and the odour molecules escape.
Oh, and the container is permanently tainted, too.
never had that problem ginge if you stand them in bicarb for a while after you have done with the "smelly stuff" and believe or not that's what they were really developed for
