How To Clean Toilet Siphon Jet?

Did you notice that water is taking time to flow from the toilet tank to the bowl, thus significantly affecting the toilet flushing capability? For most of us, the situation is quite frustrating. Even some users plan to buy a new toilet.

Due to clogging, water from the tank slowly enters the bowl, resulting in weak siphon action, and the user needs to flush the toilet 2-3 times.


In toilets, water enters the bowl through 2 channels; most of the water dumped into the bowl through a siphon jet parallel to the toilet trap. The remaining water enters the bowl through jets located on the rim of the toilet. They are positioned at an angle to create a swirling effect.

The siphoned jets are small holes in the toilet bowl spacing less than an inch wide. These tiny holes allow water from the tank to flow down into the bowl. These jets are located at a dark location; if not regularly clean, it gets infested with mold, debris, mineral deposits, especially calcium weakening the toilet flushing. The jet holes give a conducive environment for the growth of fungi and bacteria.

While cleaning the toilet, people emphasize rim jets and ignore the siphon jet, which plays a vital role in flushing the waste. This guide will show you how to effectively clean the toilet siphon jet and the rim jets.

Inspecting the Siphon Jet

Before starting the cleaning process, inspect the siphon jet using a small mirror. Look into the bowl to see jets; if clogged, you will notice dark orange and black spots or scaly deposits. The orange areas indicate the presence of bacteria, while light and scaly deposits are mineral deposits. There is a good chance both bacteria and mineral deposits exist at the same time.

How To Clean a Toilet Siphon Jets?

You can use some simple working methods to remove the mineral buildup and bacteria from your toilet siphon jets.

1. Cleaning with Vinegar

If your siphon jet and rim holes are clogged with minerals, cleaning with Vinegar will be an effective technique. In this method of removing the minerals, you will need some supplies.

Materials Needed

  • Mirror
  • Cleaning Detergents
  • Rubber Gloves
  • Spray bottle
  • Face Mask
  • White Vinegar
  • Toilet Cleaning brush


  • Wear gloves, use the mirror to inspect the jet holes for determining the amount of dirt.
  • For some people, the vinegar odor is strong, so we strongly recommend using a face mask.
  • Take one cup of vinegar and boil it. Allow it to cool and add in the spray bottle.
  • Now spray the Vinegar underneath the rim and siphon jets.
  • Wait for an hour allowing the minerals and debris to slowly spill down the bowl.
  • After an hour, gently scrub with a brush. Steadily move the brush around the rim until all the dirt leaves the siphon jets.
  • Again use the mirror to check for any remaining dirt. In case there is some dirt, repeat the steps until the holes are clean. Sometimes if minerals have been there for a long time, the dirt will take time to get removed. You might need cleaning detergent and aggressive scrubbing to clean the jets.
  • Once you are done with the process, use a toilet brush and cleaner to clean the bowl.

2. Duct Tape Method

In this method of removing the debris and mineral, Vinegar will be used with duct tape to trap the Vinegar for a longer time.

Material Needed

  • Vinegar
  • Brush
  • Duct Tape
  • Mirror


  • Clean the toilet using a brush.
  • Turn off the water supply to the toilet tank.
  • Flush the tank for one last time to remove all the water.
  • Now dry the bowl and place the duct tape under the rim, firmly coverup the water jets.
  • Fill the toilet tank with Vinegar and flush it.
  • The duct tape will seal the water allowing the rim and jets to remain soaked in the Vinegar softening the calcium layers stuck in holes.
  • After an hour, remove the duct tape and gently scrub to check if the dirt has been removed.

Siphons jet holes are the prime location for bacteria growth. If the jet holes are blocked due to bacteria, you need to use disinfectants and detergents to kill the bacteria.

Materials Needed

  • A Bucket
  • Soft hand brush
  • Vinegar
  • Detergent or Infectant
  • Baking soda


  • Flush down water from the tank to get a sight of bacteria’s existence.
  • Create a paste using baking soda and Vinegar. Ensure the paste is thick enough to stick around the siphon holes.
  • Precisely apply the paste make sure the paste gets into the siphon jet holes.
  • Wait for half an hour.
  • Wipe down the paste using the rag.
  • Use the mirror to check if all the bacteria is removed. If the fraction of bacteria is still intact, repeat the same procedure to get a clean siphon jet.

Keeping Your Jets Clean

Once you have completed the siphon jet cleaning, regularly clean the bowl to maintain toilet hygiene. For removing the bacteria, use manufacturer recommended bleach, avoid using abrasive cleaners. These can damage the rubber parts, e.g., the flapper valve. The extensive damage could also nullify the warranty.

To remove the mineral buildup, monthly pour warm Vinegar into the tank and wait for an hour. It will remove all the mineral deposits. You can also use wire or brush to clean.

To clear consistent mineral buildup, occasionally pour warm Vinegar into your tank and let sit for a half-hour before flushing. This should be enough to break up any mineral deposits as they form. Use your wire or brush to clean the jet openings and regularly wash with your standard brush and cleaner. We hope our t
