Best Toilet Cleaners for Septic System Tanks | Septic-Safe Cleaning

Plant based toilet bowl cleaners are best option for septic systems.

If you have a septic system on your property like we do, you’re probably looking for cleaning products that are septic-safe.

Harsh, toxic chemicals can actually kill the “healthy bacteria” that thrive inside your septic system and naturally break down the waste inside the tank. Many commercial toilet bowl cleaners contain bleach and some even are made with hydrochloric acid. While the acid does effectively dissolve the calcium carbonate deposits in the water it’s also a harmful chemical that can contaminate well water and kill off the bacteria in your septic system. 

Some experts have confirmed that a modest amount of chlorine bleach will kill off the good bacteria in your tank. However, even on the label of Clorox® Toilet Bowl Cleaner – the company claims that bleach is safe to use in septic systems.

With all this confusing marketing it’s hard for consumers to really know what to products to buy that will actually clean their bathroom but at the same time not do harm to the natural balance of their waste disposal systems.

The best toilet cleaners for septic tanks are ones made from natural and plant based ingredients since they are biodegradable and use cleaning agents that easily break down. You can make your own cleaner at home, like my grandmother did with simple and natural ingredients, many of which you may already have around the house.

DIY Septic Safe toilet cleaner

Here is the easiest cleaner I know how to make that actually works:

  • ½ cup baking soda
  • 1 cup white vinegar
  • ½ teaspoon tea tree essential oil (click to find out why it’s used in natural cleaning recipes)

Mix the ingredients in a spray bottle, spray the inside of the bowl and wait for several minutes before scrubbing entire inside of bowl with a toilet brush.

If you want something more heavy duty to get out stains on the bowl you can substitute borax for the baking soda

  • ¾ cup borax
  • 1 cup white vinegar
  • Add 15-20 drops of essential oil. You can use tea tree oil again and also mix in a fragrant oil like lemon or lavender to give it a fresh smell.

If the toilet is really duty or has stubborn stains, you can spray this on and leave it for several hours or even over night before srubbing.


If you don’t want to bother making your own cleaning products, there are several commercial products available that are plant based and safe to use, like this Toilet Bowl Cleaner by Eco-Me.

If you’re not a fan of peppermint scent, you may prefer the pine fresh scent of this Ecover Toilet Cleaner.

The Better Life company was founded by two dads that wanted to make safe cleaning supplies for a toxic-free home. You may be familiar with the company already as millions saw them on Shark Tank when they pitched their cleaning supply company. The pitch ended with a somewhat shocking effect where one of the founders (Kevin Tibbs), sprayed their What-EVER! all purpose cleaner into his mouth!

The stunt (and the products) convinced the judges and they ended up landing a huge deal with one of the “sharks”. Since then the company has had huge growth and now sells a wide variety of household cleaning supplies that are non-toxic and also septic safe.

Scene from Shark Tank:


Here are a few things to consider when purchasing a toilet bowl cleaner, and bathroom cleaning supplies in general, if you have a septic system.

First some tips that can help:safe toilet cleaner for septic tanks

As we mention in our article about how a septic system works, in a properly functioning system, the tank needs to have a healthy balance of bacteria to break down the solids inside the tank.

Large amounts of harsh chemicals can upset the balance of the tank and kill off the “good bacteria” that is working to process your household waste. Therefore it’s recommended that whenever possible you use bio-degradable cleaning products and avoid ammonia, anti-bacterial and chlorine based products.  

While we do not use any enzymes, many people do use them to maintain the healthy balance of bacteria in their septic tank, you can also see how to make an easy DIY septic system activator here. 

Conclusion

no toxic label from cleaning productsPurchasing the right toilet cleaner that does not have negative impacts on the septic system is not difficult. All the user has to consider is its ingredient to determine whether it is biodegradable or not.

Toilet cleaners made from plant materials are usually the ideal cleaners that are suitable for septic systems because they are non-toxic and easily biodegradable. In the long run these will help maintain the balance in your tank and make it work more efficiently lessening the frequency that you have to get it pumped.
