Do NOT mix bleach and ammonia in the toilet bowl in an enclosed space. Bleach + ammonia = Chlorine gas = a weapon used in WWI and WWII as a chemical warfare agent causing chemical burns in the airway and lungs.
It will leave you intubated, ventilated, and full of lines going in and out and pretty much wherever we can find space. When the swelling in your airway has finally gone down enough, your breathing muscles will be so weak you will need a tracheostomy in order to wean off of the ventilator.
So please, Use vinegar, water, lemon juice and tea tree oil instead. No risk of toxic fumes, good for the environment, plus you avoid a ticket to the ICU. Win-win-win!
I See You, RN
