Plant based toilet bowl cleaners are best option.

If you have a septic system on your property like we do, you’ve probably heard that it’s best to use cleaning products that are septic-safe.  Harsh, toxic chemicals can actually kill the “healthy bacteria” that thrives inside your septic system and naturally breaks down the waste inside the tank.

The best toilet cleaners for septic tanks are ones made from natural and plant ingredients since they are biodegradable and safe for septic systems, like this Toilet Bowl Cleaner by Eco-Me.

Flushing corrosive or hazardous cleaners down the drain can be detrimental to your septic tank. A very large amount of harsh chemicals can also be too much for your system to handle properly, preventing the ingredients from being broken down and eventually leaching out thru the drain field which is a health hazard.

The other problem is that solids build up quicker in an inefficient tank -requiring you to get your septic tank pumped more often -which can get very expensive.

Luckily, there is a wide range of cleaning products on the market now that are safe to use in septic tanks and use more natural ingredients. Using a toilet cleaner that is made for septic systems helps prevent your septic system from backing up, prevents damage from toxic chemicals produced from toilet cleaners and is better overall for your home and the environment.

Here are a few products to consider using if you have a septic tank system:

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

  • Avoiding pouring large amounts of cleaning products or household chemicals down your drain at the same time.
  • When putting cleaning products down the drain, dilute with plenty of water and/or flush with additional water.
  • Use single ply toilet paper that is specifically designed for septic and RV toilets and breaks down easier than standard toilet paper.
  • Use non-chlorine, non-ammonia, non-antibacterial, non-toxic and bio-degradable cleaning products.
  • Avoid putting solvents and solvent-based products or garden chemicals such as pesticides down the drain.
  • Contact your local recycling center or waste disposal center to find closest drop-off location for toxic products.

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.
