How to Choose a Septic Tank Cleaner
Choosing a toilet cleaner can be quite straightforward, as modern toilets are designed to be tough and durable. If you have a septic tank, however, you will need to be far more careful as an abrasive cleaner could cause unseen and costly damage to your tank. There are a few general rules you should follow to ensure you choose a safe cleaner.
Avoid Cleaners With Harsh Chemicals
Many toilet cleaners contain harsh chemicals. The two most common are bleach and hydrochloric acid, which can damage septic tanks in large quantities or over a long period. These chemicals hinder or destroy the bacteria that septic systems need to function properly (1).
You should also be wary of cleaners containing ammonia, phosphates, or solvents. These are less common but have the same effect as bleach and acid, so they will also interfere with your tank’s operation.
Be Careful
If you decide to use a toilet cleaner containing harsh chemicals, ensure you are protected. This means wearing gloves, eye protection, and clothes that cover your skin. Some toilet cleaners can burn the skin or damage your eyes. (3)
You should also remove any mats and other items from around the toilet. This ensures they won’t be damaged if you accidentally splash or spill your cleaner.
Try Natural Toilet Cleaners
In stark contrast to chemical cleaners, you can also use natural cleaners such as white vinegar, baking soda, or lemon juice. You can be confident that these will not cause any damage to your toilet or septic tank.
If you enjoy DIY and have some spare time, you can create your own toilet cleaner. In addition to the natural cleaners we already mentioned, these might contain alcohol, citric acid, oils, or dried spices.
Natural cleaners provide an affordable, non-toxic, and eco-friendly way to clean, disinfect and deodorize your toilet.
Go Eco-Friendly and Efficient
If you want to clean effectively without damaging the environment, you can use safe and mild toilet cleaners. These might clean your toilet more effectively than natural cleaners, without being as harsh as the most powerful chemical cleaners.
Look for products that are labeled non-toxic, biodegradable, and environmentally friendly. These will prevent you from damaging your septic tank, polluting underground water, or exposing your household to harmful chemicals.
Per the United States Environmental Protection Agency, the safest option is to use “green” cleaners that don’t contain petroleum-based solvents. You can even check on their website whether or not a potential purchase is an eco-friendly option (4).
