This seems like a 'no brainer' to me. Cleaning with vinegar (and baking soda) is the cheapest, most effective way to clean anything! Boy, will it save you money over commercial cleaning products!
I use vinegar to clean all over my house. Get some spray bottles at the big box store (label them so you know what is in it) and store it just as you would any commercial cleaner. Mine live under my kitchen sink. Here are some of the ways you can use vinegar and eliminate the cost of commercial cleaning products:
Windows, counter tops, kitchen table, and other general cleaning needs: one part vinegar and one part water. Spray and wipe.
Kitchen sink: sprinkle baking soda (just as you would commercial cleaner) and then spray a few squirts of vinegar and water. Scrub with a sponge.
Shower stall, bathtub, toilet and other bathroom surfaces: Mix vinegar with some dish washing soap, spray and let it sit for a few hours. Wipe clean. (You can see more details on how to make this cleaner and clean your bathroom with it here.)
Laundry: Use vinegar (full strength) in the rinse cycle in place of fabric softener.
Dish washing rinse aid: Let your rinse aid dispenser completely empty and then fill it with vinegar (full strength).
Garbage disposal: Freeze some vinegar in ice cube trays, put a couple of cubes in the garbage disposal and turn it on.
Round Up replacement: OK, this isn't really a cleaning product, but it is a chemical you don't have to purchase! Spray the weed with vinegar (full strength). Works great for weeds that crop up between sections of concrete or in your landscaping.
When you run out of a cleaning product, instead of purchasing a new bottle, replace it with vinegar! You will get a safe, chemical free, effective cleaner that will save you money!
