The most difficult part of cleaning a toilet is getting down on your hands and knees to scrub the siphon. We’ve all been there, trying to get the stains off from inside the bowl with toothbrushes or other long objects. This can be frustrating because it’s hard to reach and maneuver these items in such tight quarters. Often, our best efforts are left wanting, and we’re forced to use chemicals that still leave us with an unpleasant experience every time we go sit on that seat (which is why I’m sitting here writing this). But now there’s a relief for those toilet-cleaning woes! In this guide, I will discuss how to clean toilet siphons. 

Most bathrooms have a siphon, which keeps the toilet empty and clean after washing. However, when the spouts get clogged, a bathroom doesn’t wash properly, leaving you in a nasty mess. That’s why it’s important to know how to properly clean a siphon toilet to keep it in good condition and free of bacteria.

How to Clean the Toilet Siphon

To work efficiently and safely, you will need the following materials:

  • Vinegar
  • Soda bicarbonate
  • Funnel
  • Sponge
  • Bucket
  • 3/16 inch L-Allen key.
  • Latex gloves

Using Toilet brush

  • Since we’re using vinegar to clean the spouts and the rim of the siphon, you’ll need to empty the cistern and toilet first. This allows the vinegar to act directly on mineral deposits.
  • Shut off the water supply to the toilet. There is a shut-off valve on the wall behind the bathroom. Turn it clockwise and if you have a push-pull valve, pull it out. Modern versions of the Duo set are now available worldwide and save the average household 67% of their normal water usage.
  • Rinse and hold the dishwasher handle to drain as much water as possible.
  • Lift the toilet lid and put it in a safe place to prevent it from falling or breaking.
  • Use a sponge to catch the water from the bottom of the tank and push it into the bucket. Dry the tank.
  • Wipe the water off the lower part of the bowl with a wipe. Unlike tank water, this water is dirty, and gloves must be worn. The water acts like a barrier preventing sewage from getting into your toilet, so hurry up with the next few steps.
  • Cover the Nozzles with a Channel
  • If you’re not sure what the edge jets look like, take a small mirror by the edge of the toilet and flip it over. You will see the little holes and how clogged / dirty they are.
  • Cover all of the holes with tape so that vinegar doesn’t run into the bowl as quickly as water.

Using Vinegar

  • If the siphon holes and rim are clogged, it means that there are too many minerals in the toilet, too. There is no point in cleaning the rim nozzles and making the tank dirty. After a while, minerals in the tank clog the rim nozzles.
  • Pour the white vinegar down the toilet, making sure to cover any stains. Then, at that point, pour vinegar on the edge and channel from the spout.
  • Inside the tank is a large pipe with a small pipe attached to it called an overflow tube? Put a funnel in the overflow pipe and pour in the vinegar. The overflow tube is connected to the drain valve. Ensure you add enough vinegar to replace the water with the water at the bottom of the bowl.

Clean The Rim Jet With The Wrench.

  • After an hour, remove the tape and drain the vinegar. Insert an Allen key into each hole in the bezel and turn it to make sure they are fully open.
  • The L-shaped hex wrench works great because you can hold it and turn it. If you don’t have the right size Allen key, you can use a piece of wire.

Flush the Toilet 

  • After flushing, push the white vinegar out of the cistern through nozzles on the edges that are not clogged with dissolved minerals. The vinegar from the bottom of the bowl will squeeze out, and the vinegar from the container will replace it.
  • Use a spray bottle to spray the disinfectant into the toilet siphon, paying more attention to where the stains are soaked.

Add Boiling Soda

  • Slowly add 1 cup of baking soda to the bathroom. Since baking soda is alkaline and vinegar is a weak acid, an oscillatory reaction can occur, so it is very important to add baking soda slowly.
  • Use a toilet brush to swirl the solution around the bowl, paying special attention to the edge every 5 minutes for 30 minutes.

Clean the Tank

Use a stiff-bristled brush or cleaning sponge to remove stains from the cistern, especially on the sides and bottom. Use a toothbrush in small areas that the hand brush cannot reach until the container is clean.

Cleaning the Rim Holes, Disposal, and Siphon Jet

  • With a toilet brush, vigorously scrub the edge of the toilet bowl to remove any remaining stains and mineral build-up. In a bowl, look for hard water marks and wipe them off.
  • Stick your finger (with gloves) into the siphon nozzle to check for any calcium left. Now that the vinegar has dissolved, rinsing should gently push it down the drain.

The Moment Of Truth

Open the water shut-off valve and allow the tank to fill with water. Rinse and carefully watch how quickly the water flows into the jar. Also, make sure that the toilet is properly cleaned.

How to Clean Your Toilet’s Siphon Jets

Here are some methods you can use to remove mineral build-up from the toilet’s siphon jets. If they’re not too messy, the first way is a quick and easy way to fix the problem.

  • Take some paper towels, soak them in white vinegar, and remove some to keep them moist but not dripping. Remove some cleaning gloves and hide the vinegar-soaked paper towels under the toilet bowl rim, adding as needed until the area under the rim is completely covered.
  • Leave the bathroom alone for a few hours to let the vinegar soak in, then remove and discard the paper towels. Use a toilet brush and your favorite toilet bowl cleaner to scrub the edge and rinse a few times to remove any loose dirt.
  • Start cleaning under the toilet rim with a toilet brush and your favorite toilet cleaner. Wash to rinse.
  • Turn off the toilet tank and flush to empty the siphon jet.
  • Block the siphon jet with some tape. (Don’t worry, the tape will come out easily later.)
  • Pour 1 liter of white vinegar into your toilet. Wash the bathroom once and leave it overnight.
  • In the morning, remove the tape from the jet and open the faucet again. Flush the toilet once or twice to remove all traces of vinegar and minerals.

How to Clean Toilet Siphons: FAQs 

What are bathroom siphons?

The siphon nozzles are small holes under the rim of the bowl. If these nozzles are clogged, your bathroom won’t get properly clean. Rinse and watch the flow of water. It should spin. If it goes straight down, the holes need cleaning.

How do I clean under the rim of my bathroom?

Proceed as follows to disinfect and disinfect:

  • Flush the toilet before cleaning.
  • Apply 4 ounces. Also, seal the container under the rim and do not close the lid.
  • Wait at least 10 minutes.
  • Thoroughly clean the entire bowl under the rim.
  • Wash and rinse the brush with fresh water.
  • Repeat as needed.

What’s that black thing under the rim of the toilet?

Because sediment from the water builds up under the edge of the toilet, it can take 24 to 48 hours for colonies to start multiplying. As it grows, you’ll see what looks like spots or black rings inside the bowl. This can cause breathing problems in people as mold and powdery mildew releases small spores into the air.

How does the toilet siphon work?

It works when a certain water supply moves along the siphon knee; gravity pulls it down to a longer leg, reducing the atmospheric pressure at the siphon knee.

Should I clean my toilet tank?

Experts recommend cleaning the tank twice a year to prevent mold, rust, and grime and prevent the build-up of minerals that can damage the parts. If you do not act, unpleasant smells can get into the bathroom and parts of the toilet that can corrode and rust.

Does Coca-Cola remove limestone from the bathroom?

In addition to being a soft drink, Coca-Cola is also a great stain remover for the bathroom. Coca-Cola contains citric acid, known to remove stains, and carbonic acid dissolves limestone and some mineral deposits. Rest for an hour and let the acids destroy the stains

Can I fill the toilet tank with bleach to clean it?

If there are many sticky figs left after draining the clean water from the tank, you can spray (or pour) chlorine bleach directly on them. Then pour a gallon or two of cold water into the water tank and toilet and flush until all the bleach comes out of the toilet and tank.


Daily cleaning of the toilet minimizes stains and odors. Proper cleaning of the rim jets should also be done regularly to avoid clogging. The jet opening can be cleaned regularly with a commercially available brush and cleaner.
