Pet odor removal
We are trying to sell our house and are getting feedback on pet odors. We are at wit's end on what to do given everything we have done. The pets are not in the house we are selling, they are in our new house.
Here is situation and what we have done:
1. We had cats and kept their litter box and food in a large closet wiht a pet door under the stairs, concrete floor, sheetrock walls. The cats always used their litter box and didn't have accidents elsewhere. Cats have been gone from house for about 2 months. Room has been thoroughly cleaned with bleach. Rest of house has people coming in and cleaning regularly. Floors are wood (wood has been sanded and refinished since cats left) and tile. Tile has been repeatedly mopped and cleaned.
After getting feedback on pet odor, we had the concrete floor under the stairs cleaned and sealed and had the walls painted with shellac.
After all that I can't personally smell any pet odor. However, I still get feedback that it is there. I have no clue what else to do.
2. Second area was our garage in which we had our kennel for our dogs. Dogs have been gone about a month to the new house. The garage has been powerwashed but does still have an odor. We are leaving the door open to air it out periodically but that does still have an odor. Not sure what to do that help that along as well.
