Her solutions are cheap (20 Mule Team borax, white vinegar, and washing soda, all of which you can get at the grocery store!). You can also buy some Vodka and dilute it with water (25% vodka, 50% water...best to buy 80 proof), and use it in a spray bottle to disinfect door handles, faucets, etc.
Remember to keep it simple and inexpensive for yourself. I find it best to use products that are from ingredients that you could eat without dying.
