Pine oil cleaners, such as Pine Sol, contain different types of alcohols, according to New Mexico State University. These alcohols can create chloroform when combined with bleach, according to Texas State University. Chloroform is a colorless substance that can cause a person to lose consciousness.
Use caution when mixing bleach with any other household chemical or cleaning product. Bleach mixed with products containing ammonia can create chloramine gases, which are particularly poisonous, according to the Washington State Department of Health. Breathing in these gases can cause shortness of breath, wheezing and irritation of the eyes, nose and throat.Learn more about Cleaning Products
