Household septic systems are something you probably don't think about until there is a problem. To help keep it working properly, it's important to know which cleaner or cleaners to use when cleaning your home that won't harm your septic system. Because when there is a problem, with a septic system, it is usually an expensive and messy one.

More than one in five homes in the United States use a septic system to process household plumbing waste. To keep the system healthy, certain steps should be taken such as regularly scheduled pumping every three to five years to reduce sludge buildup and the installation of low-flow water fixtures and laundry appliances to reduce wastewater input to the system.

So those laundry detergents and cleaning products you currently use around the house every week; are they safe for the septic system? Our comprehensive guide provides input on which household cleaners are safe to use with septic systems.

Household Cleaning Product Ingredients

Most people want to use the most effective cleaning products to keep their homes sparkling and germ-free. But some of the same ingredients that protect people from illness-causing bacteria are not good for the bacteria that keep a septic system working properly. Bacteria are necessary for a septic system to break down the solid waste and kill pathogens that will flow into the leach field and, eventually, groundwater.

That same groundwater should be protected from chemicals classified as hazardous to humans or the environment.


Septic systems are not designed to filter out many petroleum-based chemicals such as fuels, lubricants, pesticides, or solvent-based products. Even disinfectants in large quantities can wreak havoc on the processes of a healthy septic system. It is particularly important to read labels on household products to determine if they are safe for septic systems and monitor the level of use. .

While most commercial products are safe for septic systems when used in recommended quantities (always read the labels), the better choices are "green" cleaners that do not contain petroleum-based solvents and have received the United States Environmental Protection Agency's Safer Choice designation. You can also make your products with distilled white vinegar, lemon juice, and baking soda to clean and disinfect your home.

Household Cleaning Products to Avoid

Along with petroleum-based fuels, lubricants, car maintenance products such as antifreeze, and lead-based paints, several household cleaning products should not enter a septic system:

Crystal drain cleaners: Crystal drain cleaners contain large quantities of lye and sulfuric acid or hydrochloric acid that can kill beneficial bacteria and cause corrosion. Liquid drain cleaners are diluted and move more quickly through the system making them safer to use.

Disinfectants: Large amounts of disinfectants like chlorine bleach, pine oil, phenolic, and quaternary disinfectants will kill the needed bacteria in a septic system. They should be used in limited quantities, following product directions and allowing time for the septic system bacteria to recover between uses.

Oven cleaners: Many oven cleaners contain lye and other septic-harmful chemicals. It is much safer to choose other methods for removing grease and food from oven surfaces.

Oils and solvents: Oily products such as some furniture polishes and leather conditioners should never be disposed of into a septic system, because they can smother the leach field. Solvents such as degreasers, paint thinners, and nail polish removers also upset the balance in a system and pollute the leach field groundwater. Dispose of these products at a local hazardous waste facility.
