This talk of pet odors triggered a memory. Back when we rented a duplex, the landlord was cleaning out the other side. The previous occupants had cats…..who must have marked the entire house!!
Anyway, after cleaning….the odor was still there….this is what he did: He made up little packets of apple peels and coffee…in wax paper. He put them all over the house, and left them for a couple of days. After that…..no more odor!
Maybe this might help……if so, might solve a couple of issues: no more odor, and it uses items you already have around the house…instead of having to buy something.
