Maintaining a septic system requires careful consideration of the products used in your home. Many homeowners look for natural cleaning alternatives to harsh chemicals that can damage their septic system. Borax, a common household cleaner and laundry booster, is often recommended as an eco-friendly solution—but is it actually safe for septic tanks?
Maintaining a septic system requires careful consideration of all of the products you’re pouring down the drain. Many homeowners will look for natural cleaning alternatives when they’re made aware of the possible disruption and damage traditional cleaning products can cause to their septic system. Borax, a very common household cleaner and laundry booster, is often recommended as an eco-friendly alternative solution to many abrasive and corrosive cleaning agents, but is Borax safe for septic tanks?
In this comprehensive, full-scale guide, we’ll explore:
What borax is and how it works
Whether borax is safe for septic tanks
The effects of borax on septic system bacteria
Safe alternatives for septic-friendly cleaning
Best practices for maintaining a healthy septic system
Borax, or chemically known as sodium borate, is a naturally occurring mineral which is composed of boron, sodium, oxygen, and water. Borax has been used for centuries across the world as a cleaning agent, an insect repellent, and even a laundry booster, both in the olden days and in modern times
Laundry booster – Softens water & removes stains
General cleaner – Disinfects surfaces & deodorizes
Pest control – Deters insects such ants & cockroaches
Mold & mildew remover – Kills fungi & bacteria
Toilet bowl cleaner – Breaks down mineral deposits
Borax is considered a natural cleaner, largely due to its composition free of harsh, synthetic chemicals. This composition makes it one of the most popular choices for homeowners seeking out eco-friendly, alternative clearing agents which will work well with their septic tank.
Borax is generally safe for septic tanks, unless it’s used in excess, as excess use could disrupt the delicate balance of bacteria which occurs within your septic system to break down biosolids.
Septic systems greatly rely on natural bacteria to assist in breaking down solid waste throughout the septic tank itself. These bacteria play a vital role in keeping everything functioning properly. As Borax has mild anti-bacterial and antifungal properties, it may begin to disrupt the natural bacteria composition within your septic tank if too much is used too often.
Unlike bleach, Borax is not highly disruptive to natural bacteria. It’s often considered a low-impact cleaner when compared to bleach and other strong, chemical cleaning agents.
Occasional use (small amounts) – This is considered generally safe and would not induce harm within the septic system
Frequent or excessive use – This amount of Borax use could begin to kill beneficial bacteria, resulting in a slower waste breakdown process
Highly concentrated borax solutions – This may likely disrupt the microbial activity over time
If you choose to use borax-based cleaners occasionally, your septic system should not begin to experience any adverse effects.
Borax is certainly safer than many synthetic or corrosive cleaners, yet there are still some potential risks involved if used improperly.
The beneficial bacteria within the septic tank digest the solid waste and ensure the system is still working efficiently.
Excess use of Borax may inhibit proper bacterial growth over time, leading to slower than average waste breakdown periods and possible clogs.
Borax does not break down very easily within the septic tank system, leading to buildup of Borax over time.
Larger, repeated doses could alter the pH balance, which in turn will likely affect the underlying bacterial function.
If Borax does reach the drain field, it may affect the soil bacteria which helps to filter wastewater.
High boron levels within the soil may lead to plant toxicity, which could harm nearby vegetation.
Although this is rare, when Borax is combined with hard minerals, it can create deposits within the pipes and septic lines.
These deposits could lead to an increase in the amount of clogged pipes and overall reduce flow of wastewater.
To mitigate the negative effects of using Borax in your home with a septic tank, you should try to stick to these suggestions
Limit Borax use to the occasional cleaning session
Try to stick to 1 cup or less of Borax per cleaning session
When choosing to use Borax to clean any of your toilets or sinks, dissolve the Borax with warm water first
This process helps to prevent excess concentration of Borax from entering your septic tank
Use other natural, alternative cleaning agents, such as vinegar, baking soda, and castile soap to reduce your reliance on Borax.
Avoid using Borax daily for everyday household cleaning tasks and laundry
After cleaning with Borax, be sure to flush the cleansed area with extra water to help dilute it as it enters your drain pipes.
This helps to ensure a diluted, smaller amount enters your septic tank
If you begin to notice slow drains, unusual odors, or excess backups; schedule a septic inspection.
Be sure to proactively pump your septic tank every 3-5 years to prevent any minor issues from transforming into major issues
If you want to avoid Borax altogether, you should consider these septic-friendly cleaning alternatives:
Great for septic systems and actually boost good bacteria activity
Fantastic for scrubbing sinks, tubs, and toilets
Successfully neutralizes odors without harming bacterial microbes
Naturally disinfect areas without harming septic bacteria
Perfect for removing grease, stains, and hard water buildup
Can easily be combined with baking soda for extra cleaning power
Natural, antibacterial properties without disrupting the delicate septic tank’s balance of bacteria
Works very well for cleaning sinks, countertops, and drains
An awesome, plant-based soap which is gentle and fully biodegradable
Great for multi-purpose cleaning without affecting the septic bacteria
Gently disinfects surfaces without harming the septic system
Can be easily used in place of any chemical-based toilet bowl cleaners
Possesses natural, antimicrobial properties which are effective, yet do not disrupt the bacterial balance within the septic tank
Easily add to homemade cleaning solutions for a boost of fragrance and germ-fighting capabilities
In addition to the above septic-safe cleaners, you should consider adhering to these best practices to ensure your septic system is healthy for many years to come:
A family of four should always pump their septic tank every 3-5 years
This will assist in helping to prevent sludge buildup and will ensure proper waste breakdown
Spread out your laundry loads to help avoid overflowing the system
Fix any leaky faucets to prevent excess water from flushing the delicate bacteria out of the tank.
Do NOT use bleach, ammonia, or antibacterial soaps excessively, as this will disrupt the natural bacterial processes within your septic tank
Choose biodegradable, septic-safe products instead
Do NOT park any vehicles or build structures over your septic tank’s drain field
Plant any trees and deep-rooted plants far away from the septic tank and its drain field to prevent root damage from occurring
Only flush septic-safe toilet paper and human waste
Never flush paper towels, wet wipes, or feminine hygiene products
Borax is considered generally safe for septic systems when used in moderation. Excessive use is likely to cause a great deal of harm to your septic tank’s beneficial bacteria and could slow down waste breakdown. If you do happen to use Borax for cleaning, be sure to follow all of the safe usage guidelines, properly dilute it with water, and avoid daily use.
For the best septic tank health, consider septic-safe alternative cleaning agents such as baking soda, vinegar, and castile soap. Proactive, proper septic tank maintenance and eco-friendly cleaning practices will help to keep your system running smoothly for many years to come.
