We've always known not to mix certain household chemicals because they can create toxic gases and cause health issues. I remember when I was much younger, my parents said to never mix bleach and ammonia because, besides the eye-stinging effect, it could hurt your lungs. But now, especially in the wake of COVID-19, many health organizations, and even EMS and emergency workers are reporting they're seeing a rise in dangerous chemical reactions in the home. The Puyallup Police Department, Clearwater Florida Fire Department, and others on Facebook have recently posted some dangers about creating your own 'home brewed' cleaning supplies.
