I don't trust the sprays and plug ins....especially in the winter when you have windows closed . you'll never know what your lungs are inhaling
This is what I use. Take 2-3 sheets of thick paper towel from a roll. Get a bottle of essential oil that you like...lavendar, peppermint,etc
fold sheet of paper towel up twice......dab the towel in 2 spots with the open top of the bottle
open the paper towel up.....hang one on your shower rod..... one in drape rod in bedroom....... one in drape rod in living room area.....leave doors open
repeat this every
other day as you leave the house.
I don't smoke and my stove has electric pilot, but the oils are always marked that you should be careful around flames.
Make sure it's a smell you can live with because everything in your crib will carry that scent.
rugs......good old arm and hammer baking soda, sprinkle on rug......overnight...then vacuum.
if you have a pet, or funky smell in rug.....get the arm and hammer carpet fresh......
