I’ve always heard that vinegar is your best bet. But you have to clean as much as you can first, i.e. shampoo carpets, clean drapes, etc. Then use the vinegar.
AFAIC, I don’t think there’s anything that smells worse than Febreze. Ewwww, I can’t stand the smell of that stuff. Same with Lysol…it makes me gag.
Now, can someone help me with a dead mouse smell? I had one d (beneath where it was). Unfortunately, it’s right where my computer is. It isn’t strong but I can still get a whiff of it every once in a while. My pest control guy even removed the "body."
