Commercial cleaners may do the job, but they can leave nasty traces of the toxic ingredients that they usually contain. Those toxic traces are then breathed in--or even accidentally ingested--by those who live where they've been used. One way around this is to avoid commercial cleaners altogether, relying instead on the all-natural variety. Here's how to make an all-natural alkaline cleaner.
Locate a regular spray bottle with a screw-on, screw-off the top.
Put a 1/2 teaspoon of washing soda into the spray bottle.
Add 2 teaspoons of borax to the contents of the spray bottle, then shake several times.
Add a 1/2 teaspoon of liquid detergent to the contents of the bottle, then shake well once again.
Heat up 2 cups of water in a regular pan. The water needn't reach the boiling point, but should be at least as hot as you might use for tea or hot chocolate.
Pour all of the water into the spray bottle so that it combines with the rest of your cleaner. Shake the bottle until your mixture has completely dissolved into the hot water.
Spray the dirty areas about every 6 to 9 inches or so, wiping well with a rag as you move along. If a particular dirty spot won't clean easily, try spraying it generously then allowing your mixture to sit undisturbed for a few minutes. This will allow it to fight the filth, after which you should be able to wipe away with the rag.
