The U.S. Environmental Protection Agency (EPA) considers leftover household products as hazardous wastes, such as:
- Batteries
- Cleaners
- Gasoline
- Miscellaneous chemicals
- Oils
- Paints
- Pesticides
- Petroleum products
These wastes can catch fire, react or explode under certain circumstances, and can be corrosive or toxic; therefore, they need to be disposed of properly - not down the drain!
