I don't use synthetic dishwashing liquid, because it's completely unnecessary. Anything that separates water from everything else is not going to do good things in your digestive tract. Other effects... who knows?
I don't drink tap water, which in my country has about twenty disinfectants in it. What do disinfectants do? They are poisons which kill micro-organisms. The idea is that they're strong enough to harm them but weak enough for us to handle. But are they? What about our gut microflora and such?
I don't use synthetic chemical surface cleaners or anything else like that. There are natural options, DIY options, and it generally works out cheaper than purchasing the mass produced synthetic garbage.
And yes, I've been tested, and have super-sperm. Kid is on the way too.
