Here’s a few things to try:
– Run a full pot or kettle of boiling water down your kitchen drain. Often times you’ll find the smell is actually coming from your drain.
– Citrus rinds … same thing, thrown them down your drain, and flip on the garburator.
– If you have a vent above your stove, make sure you’re running it the entire time you’re cooking.
– Make some coffee, that is if you like the smell of coffee. It can easily overpower other smells lingering in your kitchen.
