Always label containers and store them out of reach or in a locked cabinet.

All-purpose Cleaner
Add 3 tsp. liquid soap or ¼ cup Borax to 1 gallon water.

Window Spray
Use ½ cup vinegar mixed with one gallon of water.

Disinfectant
Mix ¼ cup Borax with ½ gallon of water. Or, make a solution of 3 Tbs. liquid soap, 2 cups water, and 20-30 drops of tea tree oil (which is a natural disinfectant). Hydrogen peroxide is also a proven sanitizer.

Mold Remover
If you discover mold and mildew in your house, first find the source of moisture and stop it. It's pointless to clean mold if it's only going to return. Remember to wear gloves and a facemask, since mold spores can be inhaled.

Use a stiff brush and hot water to scrub mold off of non-porous surfaces. Straight vinegar will kill 82% of mold, 99% of bacteria and 80% of germs.

Pour some white distilled vinegar into a spray bottle, spray on the moldy area, and let set without rinsing. It will dissipate in a few hours.

Mild Abrasive for Soap Scum and Stains
Sprinkle baking soda on the area and wipe with a damp rag.

Tub and Tile Cleanser
Mix 1 2/3 cups baking soda, 1/2 cup liquid soap, and 1/2 cup water. After mixing, add 2 Tbs. vinegar (adding vinegar too soon will cause it to react with the baking soda).  Apply, wipe, and scrub.

Clogged Drain
Pour 1 cup of baking soda down the drain followed by 3 cups of boiling water. Repeat. If you still have a clog, try pouring down 1 cup of vinegar. The vinegar will mix with the baking soda causing some foaming and gurgling, which hopefully dislodges the grime.

Oven Cleaner
Sprinkle a ¼-inch layer of baking soda all over the bottom. Then spray the baking soda with water until it is thoroughly dampened. Let it set and dampen the baking soda again if it is drying out. Leave it overnight and in the morning, the baking soda and grime can effortlessly be scooped out of the oven with a sponge.
