From Toilet Paper to Cleaners: What’s Safe for Your Septic System?


Maintaining a septic system may not be the most glamorous task, but it’s crucial for keeping your home’s plumbing functioning smoothly. Septic systems are delicate ecosystems, and using the wrong products can disrupt their balance, leading to costly repairs. This blog will walk you through which household items—like toilet paper and cleaning products—are septic-safe, ensuring the longevity of your system.

1. Septic-Safe Toilet Paper: What to Look For
The toilet paper you choose plays a significant role in maintaining a healthy septic system. Not all toilet paper is created equal, and some are better suited for septic tanks than others.

What to look for:
  • Biodegradable toilet paper: This type of paper breaks down more easily than regular toilet paper, reducing the risk of clogging your septic system. It dissolves quickly and doesn’t overwhelm the bacteria in your septic tank, which are essential for breaking down waste.
  • Single-ply toilet paper: While you might prefer the comfort of thick, plush toilet paper, single-ply is the best option for your septic tank. It disintegrates faster, meaning less buildup in your pipes and septic tank.
  • Septic-safe labeling: Many brands offer toilet paper specifically marked as "septic-safe." These products are tested to ensure they break down efficiently.

Brands to consider:
  • Scott Rapid-Dissolving Toilet Paper
  • Cottonelle Ultra CleanCare
  • Seventh Generation Toilet Paper (made from recycled materials)

2. Cleaning Products: Choose Natural Over Harsh Chemicals
Septic systems rely on natural bacteria to break down waste, and introducing harsh chemicals can disrupt this process. Cleaning products that contain bleach, ammonia, or other corrosive substances can kill the helpful bacteria and damage the tank.

Septic-safe cleaning product guidelines:
  • Avoid bleach-based cleaners: While bleach is a powerful disinfectant, it can harm your septic system if used in large quantities. Opt for milder alternatives such as white vinegar or baking soda, which clean effectively without disturbing the bacteria balance.
  • Limit antibacterial products: Many household cleaners, soaps, and detergents contain antibacterial ingredients that kill both harmful and beneficial bacteria. Try to minimize their use and choose eco-friendly, biodegradable alternatives whenever possible.
  • Use plant-based cleaners: Products made from natural, non-toxic ingredients are better for your septic tank. Look for items labeled "septic-safe" or those that are free from harsh chemicals.

Septic-safe cleaning products:
  • For toilets and bathrooms: Use baking soda and white vinegar as a natural cleaner. You can also use a toilet brush with biodegradable cleaning solutions to scrub away grime.
  • For floors and surfaces: Opt for natural, plant-based cleaners like Mrs. Meyer’s Clean Day or Seventh Generation Multi-Surface Cleaner. These products use natural ingredients and won’t interfere with your septic system.
  • For drains: If you need to clear clogs, avoid using chemical drain cleaners. Instead, use a plunger, a drain snake, or a homemade solution of baking soda and vinegar.

3. Laundry Detergent: Choose Wisely
The detergents you use in your laundry can significantly affect your septic system. Many traditional detergents contain phosphorus and other chemicals that can harm septic tanks.

Laundry tips for a septic-friendly home:
  • Opt for liquid detergents: Powdered detergents can clump together inside the tank, potentially causing blockages. Liquid detergents dissolve better and are easier on your system.
  • Low-suds formulas: High-efficiency washers use low-suds detergents that are also better for septic systems, as excessive suds can overload your tank.
  • Eco-friendly detergents: Products like Seventh Generation or Ecover Laundry Detergent are designed to be both gentle on your clothes and safe for septic systems.

Brands to consider:
  • Seventh Generation Free & Clear
  • ECOS Laundry Detergent
  • Biokleen Laundry Detergent

4. Dishwashing Liquids and Detergents
Like laundry detergents, dishwashing liquids and detergents can also affect your septic system. Phosphate-free and biodegradable formulas are the way to go.

What to use:
  • Non-toxic dish soap: Look for biodegradable, phosphate-free dish soaps such as Method or Mrs. Meyer’s. These products are gentle on your septic system and the environment.
  • Use the dishwasher efficiently: Avoid overloading your dishwasher and choose eco-friendly, septic-safe dishwasher detergents.

Septic-safe dishwashing brands:
  • Method Dish Soap
  • Seventh Generation Dishwasher Detergent
  • Ecover Zero Dish Soap

5. Personal Care Products: What You Flush Matters
Your septic system isn’t just affected by cleaning products and detergents, but also by personal care items that are flushed down the toilet. Avoid flushing anything other than septic-safe toilet paper, as other items can clog the system.

What to avoid:
  • Flushable wipes: Despite the "flushable" label, these wipes do not break down and easily and quickly causes blockages in your septic system.
  • Feminine hygiene products: These products should never be flushed, as they can cause serious clogs and damage to your system.
  • Cotton balls, Q-tips, and dental floss: All of these items should be thrown in the trash rather than flushed, as they do not break down in septic tanks.

Caring for your septic system means being mindful of what goes down your drains and toilet. By choosing septic-safe toilet paper, cleaning products, laundry detergents, and dish soaps, you can protect your system from damage and extend its life. Stick to biodegradable, natural, and eco-friendly products, and you’ll not only maintain your septic tank but also reduce your environmental footprint.
By taking these simple steps, you can ensure that your septic system stays healthy and trouble-free for years to come.
