How to Choose a Toilet Cleaner That is Safe for Your Septic System

Before we get into our reviews for the best products on the market, we are going to go over some important things you need to take into consideration before you choose a septic-safe toilet cleaning product:

Disinfectant Capabilities

There is no use in purchasing any household cleaner if it does not properly disinfect the area you’re cleaning. While it is important to choose a product that will not harm your septic system once it has entered the septic tank, you still want a cleaning product that will kill the harmful types of bacteria that can grow and spread on the interior and exterior surfaces of your toilet.

Easy Spray Nozzle

The best cleaning products are packaged in bottles that have easy spray nozzles. This allows you to get the cleaning spray or gel in the most difficult to reach areas of your toilet bowl, including under the rim. These areas are where bacteria, mold, and mildew tend to grow, so it is really important that you reach them. Look for angled nozzles, rather than simple threaded caps.

These angled nozzles really let you direct the product under the rim, which allows you to scrub it in properly with your toilet brush.

Biodegradable Ingredients

As mentioned, it is important that your toilet cleaning product does not destroy your septic system’s ability to break waste down into more manageable components. This is why the best septic-friendly cleaning products are made from biodegradable ingredients that will not linger in your septic system and destroy its natural bacterial and enzyme makeup. Synthetic fragrances, dyes, and harsh chemicals can all damage your septic system and the surrounding environment, which is why we always recommend cleaning products that are made from natural, biodegradable ingredients.

Deodorizing Properties

Nobody wants to deal with a stinky toilet, which is why you should always look for deodorizing properties in a cleaning product, rather than artificial fragrances that simply cover up bad smells for a short period of time. As a bonus, most of the deodorizing ingredients also help to whiten and brighten your toilet bowl, so your toilet will have a fresher scent and a spotless appearance!

Review

Mrs. Meyer’s Clean Day makes a wide variety of natural, plant-based cleaning products. This septic system safe toilet bowl cleaner is the perfect option for anyone that is looking for an effective product that is made without harsh, unnatural ingredients.

We really liked that it is made without phthalates, chlorine, artificial colors, and bleach. The fact that it is also available at a fair price means that this toilet cleaner from Mrs. Meyer’s Clean Day is an excellent option!

Bottom Line

You can choose an unscented version, or your choice of lavender, orange, or mint scents. Not only is it great for your septic system, it works really well as a cleaning product, as it can help remove stains very effectively.

Why Does it Matter What Toilet Cleaner I Use With a Septic System?

There are two main reasons why you need to use a septic-safe cleaning product when you are using a toilet that is connected to a septic system. For starters, you do not want to choose a product that will completely eliminate the bacteria and microorganisms inside your septic tank. This is because these microscopic organisms actually help to break down the waste and toilet paper inside your septic tank, which allows the tank to store more waste before it needs to be emptied.

The second reason why it is important to choose the right cleaning product is the fact that some of the water that gets flushed down the toilet will be filtered and released back into the natural groundwater system. If the water is filled with harmful chemicals, it can become an environmental hazard and contaminate water that is needed to sustain plant and animal life in the area.

By choosing the right cleaning product, you will make sure that your septic system works correctly and you are doing your part to protect groundwater reserves and the surrounding environment.

Types of Toilet Cleaners That Are Septic Safe

Not all cleaners can be used with a septic system. Here are some that are:

Plant-Based and Biodegradable Commercial Toilet Cleaners

As the name suggests, these are toilet cleaning products that are made from natural ingredients. In most cases, they use plant-based ingredients, rather than harsh chemicals. After the products have been flushed, they will begin to biodegrade, so they will not harm your septic system or the environment that surrounds your septic tank. As an added bonus, these natural products are much safer to use if you have small children or curious pets, as they are far less toxic than products that contain dangerous chemicals, like bleach!

Homemade Toilet Cleaning Mixtures

While they are rarely as effective, you can also create your own septic-safe toilet cleaning mixture. Natural and biodegradable ingredients, like white vinegar, baking soda, and lemon juice can all be used to clean your toilet. Since they are all biodegradable ingredients, they will not harm the interior of your septic system and they pose very little risk to the wider environment.

Septic-Safe Drop-in Tabs

These cleaning products are not delivered in the form of a liquid spray or gel. They are small tablets that you drop into your toilet. As they dissolve, they release natural ingredients that help loosen up stains and mineral deposits. Once they have fully dissolved inside the toilet bowl, you can use a toilet scrubbing brush to clean the interior of the bowl. Since they are mostly baking soda-based, they will not harm your septic tank or the surrounding groundwater.

Top Brands in the Septic-Safe Toilet Cleaner Space

Mrs. Meyers

This innovative brand has a simple mission – create effective, plant-based cleaning products that have garden-inspired scents. As you would expect, their products are free from harsh chemicals that would otherwise pose a risk to the environment and septic systems. They also infuse their cleaning products with essential oils that leave lasting scents, so your toilet will smell better than ever!

Camco

Camco was founded in 1966 and has grown to become a major manufacturer of RV and boat supplies. Their cleaning products are specifically tailored to the unique needs of mobile septic systems, so there is no risk that they will damage your septic system or the surrounding environment.
