Query: Etches Plastics

Every time I run my dishwasher with one of the major brands of dishwasher detergent, my son has an asthma attack. First, I tried the Seventh Generation powdered dishwasher detergent. My son didn't have asthma attacks with it, but it etched my plastics badly. Then I tried the Seventh Generation Lemon gel. It does not cause my son to have asthma attacks and it doesn't etch my plastics. I definitely recomend the gel. I have recently started using the Seventh Generation Laundry detergent, and I like that, too.
