You may not think much of your septic system, but it’s an important part of your property!
The health of your septic system is an often overlooked yet essential aspect of home maintenance. Household wastewater contains bad bacteria, viruses, and contaminants – a functioning septic tank will filter all that out.
Part of that maintenance is choosing the right products in your cleaning routine, since those products will go down the drain.
Keep your septic tank healthy and prevent costly repairs down the line. Here’s a round-up of cleaning products that 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 beneficial bacteria to break down and process waste. Products that contain harsh chemicals can kill that bacteria, leading to septic system malfunctions.
Septic-safe products are designed to be biodegradable and free from chemicals that could harm the bacteria in a septic tank or drain field.
They also often use plant-based or organic compounds, ensuring they break down safely and efficiently within the septic tank system.
What Ingredients Are or Aren’t Septic Safe?
Certain ingredients can give clues as to whether household and cleaning products are septic-safe or not.
However, it’s always good to check product labels to see if they specifically state they’re safe for septic tanks.
And remember, even labelled products can cause problems if used excessively. Moderation is vital in maintaining a healthy septic system.
Septic-safe ingredients
Here are some ingredients or compounds to look for in septic-friendly cleaning products:
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.
Enzymes: Some products will contain enzymes or cultures that can help to break down waste in your septic system, making them a good choice.
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.
Note that small amounts of essential oils are fine!
Non-septic safe ingredients
Some ingredients or compounds to avoid include:
Phosphates: These chemicals can encourage algae growth in local waterways when the treated wastewater is released, which can harm aquatic life.
Harsh chemicals: While they’re great at killing germs, they can also kill the beneficial bacteria in your septic system that break down waste.
Non-biodegradable components: Some items – particularly in personal care products like wipes or certain types of toilet paper – are not biodegradable and can lead to clogs in your septic tank system.
Petroleum-based solvents: These can kill the beneficial bacteria in your septic system and break down slowly.
Quaternary Ammonium Compounds (Quats): These are found in many disinfectants and sanitisers and can be harmful to septic systems as they are antibacterial agents.
Specific products or compounds that can harm a septic system include chlorine bleach, hydrogen peroxide, chemical drain cleaners, paint thinners, fabric softeners, and solvents.
Water softeners can also harm the essential bacteria inside a septic tank.
NOTE: You can use antibacterial soaps, detergents, and other products with a septic system – just check the product label first. Products that use biodegradable ingredients with natural antibacterial properties (such as plant extracts) may still be septic-safe.

FAQs About Septic Systems and Plumbing
Read on for some helpful info and answers to common questions about septic systems and products!
Are septic-safe and greywater-safe the same thing?
Many products are safe for both septic systems and greywater systems, but “septic-safe” and “greywater-safe” are different labels.
Greywater-safe products do not contain ingredients that will contaminate a greywater system – the system that collects wastewater from showers, washing machines, dishwashers, and sinks.
Greywater is then recycled for use in your toilet or garden. It does not necessarily go to your septic tank.
Does septic safe mean flushable?
While all septic-safe products are technically flushable, not all flushable items are safe for your septic tank.
For example, some wipes are labelled flushable but don’t break down in the septic system, leading to potential blockages and damage.
What is the difference between septic safe and regular toilet paper?
Septic-safe toilet paper is designed to break down rapidly in water, which helps prevent clogs in the septic tank.
Regular toilet paper takes longer to decompose, potentially causing issues over time.
Can you use toilet cleaner if you have a septic tank?
Yes, you can use toilet cleaners with a septic tank – if they’re septic-safe.
Avoid cleaners with harsh chemicals like bleach or ammonia that can disrupt the bacterial balance in the tank.
What should you not flush down the toilet with a septic tank?
Avoid flushing items like wet wipes (even those labelled flushable), nappies, sanitary products, cotton buds, cigarettes, and dental floss.
From the kitchen, you should never flush cooking oil, grease, food scraps, coffee grounds, and any non-biodegradable items down the toilet.
These can cause blockages and disrupt the septic system’s functions.
Are These Products Septic-Safe?
If you’re looking at other products, always check the labels to see if they’re labelled for septic-safe cleaning or personal use.
