Back when our dishwasher was working, I once tried out a "natural" dishwasher detergent. I was to use only a teaspoon, and I did, and it didn't work. At all. Egg yolk was still encrusted. Tomato sauce still clung to plates. Awful.
I can report here, however, that our diatomaceous earth get-rid-of-the-giant-black-ants-invading-our-kitchen method WORKED! They are g-o-n-e gone. Long gone. We haven't seen a scurrying black squiggle ever since I dusted the baseboards with an ample amount of the powder.
IT WORKED! The natural nontoxic method worked. Ha!
Take that petrochemical, polluting, better-living-through-chemistry, mainstream paradigm!
