FizzionPet Stain & Odor Remover 23oz Empty Spray Bottle 2 Refills

We moved in to a mobile home and they had a dog. It smells very sour in the house. Would this product work on just spraying on carpet and clean?

Can this product be used to remove cat poo stains from vinyl or linoleum flooring?

Do you think if I mixed this with 1/2 the called for amount of water (to make a concentrate) I could use a small amount in a handheld carpet cleaner?

I thought I saw on cat from hell that this was used on outdoor area where there was dirt and cats were peeing in. Does this work on outside like under decks or stairs where outside cats are going???
