I use a solution of liquid antibacterial soap, water, and a tiny bit of bleach. Read here about disenfecting properties of bleach and proper ratios
I mop the floor and wipe all surfaces with it. Make sure to wipe places touched a lot, like door handles. I usually just wipe everything. I wash all bed linens in hot soapy water. If there is a carpet I sprinkle baking soda and let it sit a few hours and vacuum it back up. Sometimes if the mattress has been soiled I also wipe down the mattress (just the surface), let it dry, then sprinkle with baking soda, let it sit for an hour and use a shop vac or a hand held vac to vac up any extra baking soda. Any soiled clothes on the floor are picked up and washed. Trash cans , puke buckets, anything else are taken to the bath tub and hosed out with the shower hose and some bleach and soap.
Bleach is only a little over a buck a gallon and you only need a little bit diluted with a lot water. It is cheap. So is baking soda, less than a buck a box. This is cheap and effective.
If you want to spend more, my second recommendation is to use Lysol Concentrate diluted as directed on the bottle, in place of the bleach.
