Thanks so much for the fast replies!
This wasn't the first time I had something exploding in there, it probably just laid around for warming up too long so it started decomposing (so you can imagine how it stanks...) Now I know better for the next time
I already tried vinegar but it just seemed to mix up with the smell... Guess I'll have to do it a few times until it helps, and sadly I can't get some bleach in near time...
Again, thank you very much!
