Don't believe your eyes when you see the commercials where
the smiling person pulls a shining dish out of greasy suds. Any
dish soap that you use should be safe enough to eat because
nothing rinses off clean. Regular dish detergents, including health
brands, are now polluted with PCBs. They also contain harmful
chemicals. Use borax for your dishes. Or use paper plates and
plastic (not styrofoam) cups.
