Cleaners
Disposal method: Hazardous waste
Items marked Caution, Caustic, Corrosive, Danger, Flammable, Poison, Volatile, or Warning are considered hazardous waste.
Not all cleaning products are hazardous waste. Even so, you should bring them to a hazardous waste drop-off site due to the chemicals used to make them. Empty bottles can be recycled unless they're labeled with one of the caution words above.
