Litter boxes
Being a cat lover/owner comes with big responsibility. By responsibility I mean having to clean out the big lumps of poop in a box. Cleaning the litter box and doing it thoroughly is important for the health of your cat and for cutting down on one of the worst house hold odors. If you use the traditional clay-type litter, scoop out solids daily and dump out everything every five to seven days. Using a dishwashing detergent or a very mild house hold cleaner, like vegetable oil-based Murphy oil Soap. After you have done that wash and rinse the box in warm water. The plastic holds on to smells so if you use any strong scents you might keep the cat away from the litter box. If the box starts looking or smelling bad dump it all out and wash the box.
Pet Urine
If pet urine seeps through a carpet or cloth it can cause a real big smell and can draw your pets back to pee on it. It is also a breeding ground for bacteria. First you want to absorb the pet urine using some paper towels. Use a I teaspoon of colorless liquid dishwashing detergent and one cup of lukewarm water. Soak up as much as possible using your towel. Once again blot the area with a solution of one part white vinegar and two part water. Cover up the area with towels, place something heavy on it and let it sit and dry.
Cooking odors
To remove the source of cooking odors, clean the kitchen surfaces. You want to disinfect it with a commercial cleaner, like pine sol. Heat rises and, is drawn too cool areas. Concentrate cleaning energy. Do this all the time you have cooking odors from fish, onions, garlic, or any other smelly odors from foods you cook.
Smoke: You can actually get rid of smoke odors easily. You should treat your smoke odors like you do with your cooking odors. Wash away the smoke residue on the surface first. Then wash your rugs and other fabric.
