Before you even get the fish out of the fridge, put about a tablespoonful of ordinary vinegar in a saucer on a work-top. It soon neutralises the smell.
Incent sticks. Be careful not to get ones too powerful. I can recommend sandalwood or cinnamon scented. I bought some from Poundland and they had fruit scented ones which were also quite nice.
Well, we've been having kippers - among the strongest-smelling of fish - for Friday breakfast weekly for decades and I can assure you that the vinegar-treatment works every time here...no need to freeze the house by opening doors and windows on these cold and frosty days!
Wonderful! A chemist once explained to me how it works, but - being utterly unscientific - I never really understood and now I can't even remember what he said!
