How To Clean Hydroponic Lines

Cleaning your hydroponic lines is essential to keeping your plants healthy. Here are some ways you can do it:

You can clean the lines by using a brush or other cleaning tool and manually scrubbing them. This method is time-consuming and will not remove all of the debris that may have been collected in the lines.

You can use a certain type of chemical cleaner that will take care of any buildup inside the pipes, but this might leave residue behind on your equipment and cause problems down the road as well.

The best way to clean out your hydroponic line is to use an air compressor with a blow gun attachment at one end, which will force air through a tube into every nook and cranny within those pipes so that only clean water flows through them once more!

“Maintaining proper hydroponic nutrient levels is crucial to the health of your plants and the longevity of your system. Our article on how to use hydroponic nutrients explains the different types of nutrients and how to use them to keep your plants thriving.”

1. Bleach

Bleach is a great disinfectant and sanitizer, but it’s not a good choice for cleaning lines. It can leave residue in your system that will make the water cloudy and could even cause root rot. 

In addition to being an unnecessary stressor on your plants, using bleach can also be dangerous for anyone who might accidentally ingest the liquid after it goes through the system.

If you choose to use bleach as a way of killing bacteria or fungi in your hydroponic setup, it’s recommended that you dilute it with water first. 

You should then allow all traces of bleach residue from previous cleansings before using this product again (or any other type of chemical).

How to Clean a Hydroponic System with Hydrogen Peroxide

2. Hydrogen Peroxide

Hydrogen peroxide is also a great option for cleaning your hydroponic drip line as it can be found in most grocery stores. 

Hydrogen peroxide does not leave any residue and it’s non-toxic, making it safe for use around your plants.

To use hydrogen peroxide to clean your drip lines, you’ll want to put some of the liquid into a spray bottle and apply it directly onto the plastic tubing. 

After spraying down the line with hydrogen peroxide, let it sit for a few minutes so that all of the bacteria can be killed off by its effects. Then just rinse off the line with water!

3. Household Vinegar

When cleaning your system, it is important to use a diluted solution of vinegar and water. Vinegar is an acid and can damage your system if not used properly.

Here’s how:

Pour 1/2 cup of white or apple cider vinegar into the reservoir.

Run the pump for 10 minutes while the solution circulates through your lines and drains back into the reservoir. 

You will see some dirt being pulled out of the tubing as well as a foam building up on top of the liquid in the reservoir; this is normal! 

Once done running through your lines, run plain water through them until all traces of vinegar are gone from both reservoirs. 

This will take anywhere between 10-15 minutes depending on how much time passes after adding it to before running plain water through again (the longer you wait between adding something like this then running plain water through afterward allows more time for things like calcium build-up inside pipes which will make them harder to clean).

4. Plumber’s Vinegar

Vinegar is well known as a natural disinfectant, so it’s no surprise that it cleans hydroponic lines as well.

Vinegar has antibacterial and antifungal properties. It is safe for use on all parts of the system, including any CO2 diffuser, air stone or pump components. 

It’s also cheap, easily accessible, and non-toxic if any gets into your system (which won’t happen).

Just make sure you don’t mix vinegar with bleach! Vinegar can react with bleach to create dangerous gases like hydrogen chloride and chlorine gas.

5. Alkaline Cleaners

You can also use a product like B-Clean, which is available at your local hydroponic store. This product is an alkaline cleaner that contains lactic acid to neutralize the pH level of your system and prevent mineral buildup. 

You can use it in a bucket or spray bottle, but you’ll need to dilute the solution with water before using it.

B-Clean works best if you mix 1 liter (34 ounces) with 5 liters (132 ounces) of water in a sprayer, pump sprayer or foamer like this one from DWC Hydroponics:

6. Peracetic Acid

Peracetic acid is a powerful disinfectant that has been used in the food industry for years to clean equipment. 

It’s a very strong oxidizer and it can be used on all types of equipment, including polyethylene lines.

Peracetic acid is also commonly used by hospitals as a high-level disinfectant because it kills bacteria, viruses and fungi so effectively.

It’s important to note that peracetic acid does not remove organic material from your hydroponic line or other equipment; you should use another cleaning method for this purpose (e.g., bleach).

7. Sodium Carbonate (Soda Ash)

Soda Ash is a very useful compound. It is usually used in the form of sodium carbonate. Soda ash can be used to clean hydroponic lines and systems by following these steps:

Make a solution of soda ash and water; 50% soda ash, 50% water is recommended for cleaning hydroponics lines

Add this solution to your system’s water supply – though we recommend starting with just a few drops first to make sure it does not have any adverse effects on plants or people

Rinse the system with plenty of fresh water until no traces of the cleaning mixture remain

8. Sodium Percarbonate

You can also clean your lines with sodium percarbonate, which is a cleaning agent that’s used as an alternative to chlorine bleach. 

Sodium percarbonate is biodegradable and non-toxic, but it can irritate your skin and eyes if you’re not careful when using it.

9. Ozone Generators

Ozone generators are the latest technology in sanitizing water in hydroponic systems. Ozone is a powerful oxidizer that can kill many types of pathogens and is used by municipal water departments to disinfect drinking water. 

However, ozone can be dangerous to humans and animals, so it’s important that you use an ozone generator properly. Ozone generators are expensive, but they require very little maintenance once they’re up and running.

10. Ozonated Water

Ozone is a natural oxidizer that can be used to clean your hydroponic system. It’s a non-toxic compound that occurs in air, and it’s produced by the sun and lightning. 

Ozone has been used for many years to disinfect drinking water, and it’s also used as part of ozone therapy for health problems such as cancer.

Ozonated water can be made by putting distilled or purified water into a container with an Ozonator (a device that produces ozone).

You’ll want to let the ozonated water sit for about 24 hours before using it on your plants or line. If you don’t have access to an Ozonator, there are other methods you can use:

Boil the water for 15 minutes before letting it cool in an open container overnight; then pour off any foam or scum into another container before rinsing out your bucket thoroughly with fresh tap water several times until all smell of bleach is gone; 

Finally, fill up one bucket full of tap/distilled/purified springwater (not mineralized) mixed with 1 teaspoon baking soda plus any nutrients needed by your plants such as A&B vitamins; then add 2 tablespoons hydrogen peroxide (H202) per gallon H202 into this solution while stirring vigorously until completely dissolved.

Lastly, add 1 tablespoon liquid dishwashing soap like Dawn Original Dishwashing Liquid which helps emulsify oil deposits so they may be washed away more easily!

11. Utilizing Uv Lights In Hydroponics Systems With Manifolds

UV lights are a great way to disinfect the water in your hydroponic system. They are a good option for maintaining a healthy, clean environment and preventing algae growth.

UV light is an integral part of the filtration system and helps reduce the harmful effects of chemical treatments. 

The UV light also eliminates many common pathogens that may be present in your plants or soil as well as provides benefits such as killing bacteria, mold, and fungus spores that can contaminate your plant’s roots.

12. Uv Lights For Systems Without Manifolds Or Plumbing

Another option is to use UV lights in systems without manifolds or plumbing. UV lights will kill bacteria and algae.

To use UV lights in your system, you need to make sure that the light is aimed at the water line of each plant’s root zone. 

You can find out how much light is reaching the root zone by placing a meter on your roots during peak sunlight hours; if there are more than 5 watts per square foot of plants, you’ll probably be okay using regular bulbs instead of expensive bulbs designed for grow rooms. 

If not, then consider replacing your regular bulbs with special grow room-style bulbs every 6 months.

Make Sure You Have The Right Stuff To Clean Your Hydroponic System

Cleaning your hydroponic system regularly is one of the most important things you can do to keep it running smoothly.

There are two basic cleaning methods you can use:

  • Warm water and vinegar (10% acetic acid) or bleached water
  • The cleaner that contains acids, surfactants, and/or enzymes


I hope this article has given you some ideas on how to clean your hydroponic lines. The best way to avoid cleaning them is to keep them clean in the first place. 

A well-maintained system will last much longer and save you time and money in the long run.
