Citric acid is a weak organic acid that can be synthesized in a lab but also naturally occurs in citrus fruits like oranges, limes, and lemons.
It can be used in food preparation but its acid qualities also make it a good ingredient in DIY cleaning products.
It not only disinfects surfaces but also helps in the removal of stains on the surfaces.
But this begs the question – is it safe for septic systems?
Well, even though acidic substances are not recommended for septic tanks, citric acid is an exception.
This naturally occurring acid is very weak when compared to other commercial acids that are used in cleaning products.
While the citric acid may kill some of the bacteria on the surfaces where it is applied, it will not get into the septic tank at the same concentration.
By the time it mixes with water and gets into the tank, the concertation will be so dilute that it will not pose any significant threat to the helpful bacteria in the septic tank.
What to Know Before You Use Citric Acid in Your Septic Tank
As we have already established, using citric acid is ok for your septic system. However, there are some important dos and don’ts that you may want to be aware of:
Use Citric Acid Moderately
You should not be too liberal with citric acid because the more you use, the higher the chances that the pH of the septic tank will be lower.
The last thing you want is to have a septic tank that is acidic as that will almost always result in a failed system—unless some intervention is taken in good time.
As a precautionary step, keep the concentration of the citric acid at or below 5%.
That should be strong enough to take care of your cleaning needs but still not too strong that it kills the bacteria in the septic tank.
Beware Of Local Regulations
As a rule of thumb, it is best to avoid using any acids that may harm your system.
However, some jurisdictions have regulations on the maximum number of acid-based substances allowed in a septic tank.
If you have already met your quota by using other cleaning products, you may be crossing the line but adding citric acid to the list.
Check with your local health department just to be sure you are not in violation of any codes.
Use Lemon/Lime Juice More
As we have already established, citric acid occurs naturally in citrus fruits.
However, the concertation of the citric acid in the fruit is not similar to that of citric acid powder.
For instance, a medium-sized lemon will contain about 3 grams of citric acid, unlike the citric acid powder which is nothing but citric acid.
This means using lemon or lime juice for cleaning is a safer option as it reduces the chances of any negative ramifications on your system.
Conclusion
To sum it up, citric acid is safe for your septic system if used properly and moderately.
It can help you clean and disinfect your home naturally without harming your septic system or the environment.
However, be sure to use it in moderation as too much of the citric acid will alter the pH pf the septic tank which may result in a failed septic system.
