I make my own dishwasher detergent. 1 c borax, 1 c baking soda and a few drops of an essential oil like lavender or orange oil. (I've heard of someone else using Rosemary oil). There was a really environmental friendly one from Whole Foods that used some part of the grapefruit. It lasted for ever (well, felt that way).
Vinegar where you put jet dry and it rinses really well. Plus no toxic fumes when you open the dishwasher because you need something from your freshly cleaned load.
I don't make my own laundry soap, but use baking soda or Borax and vinegar. Vinegar can be used in the rinse cycle and doesn't make your clothes stink. 1/4 c if you have a front loader. You might have to tinker if you have a top loader.
I use vinegar and baking soda a lot around the house, too. The BBC America show "How Clean is your House?" uses several homemade solutions. I saw the lady use a grapefruit half and salt to clean the nastiest bath tub ever. Once the acid started to go to work she then used a nylon scrubbing pad to get the rest of the gunk off. She also used baking soda, vinegar, and a tea kettle of hot water to declog a sink. (Works fairly well)
www.care2.com/greenliving has more ideas I have been experimenting with.
Thanks to all the moms with your ideas. I will try those out, too.
