The Complete List Of Cleaning Products Safe For Septic Systems In Australia

by | Jul 28, 2023 | House Cleaning

Maintaining the health of your septic system is an often overlooked yet essential aspect of home maintenance.

It’s always a good idea to pick the right cleaning products so they harmonise with your septic tank system rather than wreak havoc on it.


What does it mean if something is septic safe?

Labelling a product as “septic safe” means that the product will not disrupt the bacterial balance within your septic system.

Septic systems rely on bacteria to break down and process waste.

Products that contain harsh chemicals can kill these beneficial bacteria, leading to septic system malfunctions.

Septic safe products are designed to be biodegradable and free from chemicals that could harm your septic system.

They are also often plant-based or use organic compounds, ensuring they break down safely and efficiently within the septic tank system.


Are there specific ingredients to look for to know if a product is septic safe?

Certain ingredients can give clues as to whether household and cleaning products are septic safe or not.

Here are some key things to look for and avoid when shopping for septic-safe products:


Ingredients to Look For

  1. Plant-based ingredients: Many septic-safe products will use ingredients derived from plants instead of synthetic chemicals. These are typically easier for the bacteria in your septic system to break down.
  2. Enzymes: Some products will contain enzymes or cultures that can help to break down waste in your septic system, making them a good choice.
  3. Biodegradable components: Products labelled as biodegradable are generally a good option for septic systems. This means they can be broken down by bacteria and won’t contribute to the build-up in your tank.

Ingredients to Avoid

  1. Phosphates: These chemicals can encourage algae growth in local waterways when the treated wastewater is released, which can harm aquatic life.
  2. Bleach and other harsh chemicals: While they’re great at killing germs, they can also kill the beneficial bacteria in your septic system that break down waste.
  3. Non-biodegradable components: Some ingredients, particularly in personal care products like wipes or certain types of toilet paper, are not biodegradable and can lead to clogs in your septic system.
  4. Petroleum-based solvents: These can kill the beneficial bacteria in your septic system and break down slowly.
  5. Quaternary Ammonium Compounds (Quats): These are found in many disinfectants and sanitisers and can be harmful to septic systems as they are antibacterial agents.
  6. Anti-bacterial soaps and detergents: Similar to bleach, these products can kill the helpful bacteria in your septic system.


It’s always a good idea to look for products specifically labelled as septic safe.

But remember, even septic safe products can cause problems if used excessively.

Moderation is vital in maintaining a healthy septic system.

If you need more advice, consider asking a cleaning professional for tips on efficient cleaning whilst maintaining your septic tank.
