Was cleaning my kitchen sink just now and began wondering why anyone would use any cleanser other than baking soda for the job. It's cheap; environmentally-friendly; isn't harsh on skin, the cleaning cloth or the cleaning surface; and is as effective as any higher-priced commercial cleanser.
It does a whole lot else too. So does plain old white vinegar.
Between the two, there's no good reason for spending precious dollars on anything else to clean one's home. Or, for that matter, to clean oneself; baking soda works as well for toothpaste, shampoo and deodorant.
ETA, April 8th: There's an additional advantage to using baking soda for all your cleaning needs instead of manufactured and often environmentally harmful products: no PST, GST or HST!
