White vinegar: Absorbs odors instead of just covering them up. The vinegar smell disappears when the vinegar dries. Also kills bacteria and mold.
Baking soda: Good for scouring sinks and tubs
Washing soda: Also good for scouring sinks, tubs, and tiles
Lemon juice: Acidic, and has some antiseptic properties
Liquid Glycerin Soap: I use Wash Tyme for general cleaning.
Borax (Sodium Borate): Deodorizes and disinfects
Essential oils: Peppermint, rosemary, thyme, sweet orange, lemon, and tea tree
To Disinfect Countertops: I keep two spray bottles in my kitchen, one with white vinegar and one with hydrogen peroxide. I spray the counters with the vinegar first, and then with the hydrogen peroxide. I also use this on my cutting boards. Never mix the vinegar and hydrogen peroxide in the same bottle! Another way to disinfect cutting boards is to just rub a slice of lemon across them.

Toilet Bowl Cleaner: Pour in about a 1/4 cup of baking soda and a cup of vinegar. Let sit for a few minutes, then clean with a toilet brush.
Clogged Drains: We often just pour boiling water down our drains when they're sluggish. For more stubborn clogs, we put about a 1/2 cup of baking soda in the drain, then add a cup or so of white vinegar. Wait about 15 minutes and then pour boiling water in the drain.
Furniture Polish: Mix 2 tsp fresh lemon juice with 2 tsp olive oil. Apply to furniture with a soft, cotton cloth. Wipe furniture again with another clean, soft cloth to remove any excess oil.

I use Wash Tyme Glycerin Soap for the dishwasher and laundry. There are recipes for homemade versions out there, but I haven't tried them yet. There are also recipes for homemade oven cleaner. I haven't tried those, either, because I have a mental block about cleaning ovens. I'd rather buy a new one. Or move. ;)
