So I made some cod 4 days ago now (steamed). My house smelt pretty fishy. I expected that the small would soon go. But I was wrong. I'm now used to the smell and cannot smell it UNTIL I leave the house and return home and the stench is unreal. How can I get it to leave. I've cleaned from top to bottom. Aired out the house as much as possible. Leaving doors and windows open but still it is stinking. Someone must know what I can do.
