Quote:The volume of Co2 produced by mixing relatively small quantities of baking soda & vinegar would not be enough to affect you, your children, or pets. The purpose of the AIRTIGHT, CLOSED container is to contain the amount of Co2 at a level that produces the loss of consciousness, then a painless death. Think about people who commit suicide by CO (carbon monoxide, not carbon DIoxide) by using automobile exhaust. It has to be in a contained area or the auto has to be surrounded by debris that causes the concentration of gas to enter the passenger cabin. Baking soda & vinegar (and chlorine bleach as long as it's not mixed w/ other cleaners) are some of the BEST natural and environmentally friendly cleaners you can use. Unless you're mixing HUGE amounts of baking soda & vinegar, you can clean to your heart's content and leave your windows closed. Well said- Wish I was more eloquent - Hey I spelled that right the first time!!! Yahhhhhhhhh!!
