Use ONLY this and it leaves floor spotless. (Heavy duty floor cleaner recipe: ¼ cup white vinegar 1 tablespoon liquid dish soap ¼ cup baking soda 2 gallons tap water, very warm.) I've done this, works super well and leaves everything smelling amazing.
House smelling weird? Put two caps full of vanilla extract in a coffee cup, then place it in the oven at 300 degrees for one hour. Within twenty minutes the whole house smells like Heaven. It's actually a common realtor trick.
