This is crazy, the wife pulled this stunt a couple months ago. inherited cat from daughter, peeing on the basement floor, wife poured beach, and then the next day used ammonia and paper towels.
Chlorine gas, burned her hands a little, called me down stairs she had a plastic garbage bag with paper towels in it that was smoking. Said she never heard of it 53 year old woman. I knew it I think from middle school science class 40 years ago.
