You can probably go a lifetime without cleaning your toilet tank because when your tank gets unbearably dirty, it shows you’ve used the toilet too long and you’d probably be better off replacing the entire toilet anyway.

But this might not be the case, sometimes your toilet might be fine but your tank, not so much. Over time, rust and mineral deposits build up in your tank so it gets difficult to achieve a clean flush because when you flush, some of the dirt from the tank gets in the bowl.

In this article, you’ll be learning some different ways to clean your toilet tank and get most, if not all of the grime out. Whether you’re one to scrub or you don’t want to get your hands dirty, the methods you’ll be learning in this article will tell you all you need to know.

In addition to cleaning toilet tank problems, there are a variety of other situations that we encounter in life. For example: adding aluminum foil to the tank, cracked tanks, slow filling, etc. We have prepared tutorial information on all these problems. Please click on the links to view them.


Why Clean Your Toilet Tank?

  • Preventing Odor: Imagine perceiving a foul smell coming from your toilet area, then you flush multiple times and even use an air freshener but the smell still isn’t gone. A dirty toilet tank can emit foul odors that can permeate your bathroom and even your entire home. By regularly cleaning the tank, you can forestall these odors at their source, leaving your bathroom smelling fresh and clean.
  • Improving Hygiene: Bacteria and mold thrive in damp and dark environments, making the toilet tank an ideal breeding ground for these microorganisms. Although there’s a very low risk you’ll come in contact with any of these germs, better safe than sorry right?
  • Enhancing Efficiency: Over time, mineral deposits, like calcium and lime, can accumulate inside your toilet tank, hindering your flushing mechanism’s effectiveness. By cleaning the tank, you can remove these deposits, letting water flow freely and ensuring a powerful flush every time.
  • Preventing Plumbing Issues: Neglecting the cleaning of your toilet tank can lead to plumbing problems down the line. Buildup and sedimentation can clog the flush valve, fill valve, or other components, causing leaks, reduced water flow, or even complete toilet malfunctions. Regular cleaning helps prevent such issues and saves you from costly repairs.

Safety Precautions

Before you start cleaning your toilet tank, you need to think about your safety. While the cleaning process itself may not be hazardous, it’s always wise to take necessary precautions to protect yourself from potential risks. Here are some precautions you can follow for a safe cleaning experience.

  • Start with proper ventilation in your bathroom. Open windows or turn on the exhaust fan to allow fresh air to circulate. This helps prevent the inhalation of any fumes from cleaning solutions or disinfectants you may be using.
  • It’s advisable to wear protective gear to shield yourself from any potential splashes or contact with cleaning agents. Think rubber gloves, safety goggles, and an apron or old clothing that you don’t mind getting dirty.
  • If you’re using commercial cleaning products, carefully read and follow the instructions and warnings provided by the manufacturer. Some cleaning agents may contain harsh chemicals that can irritate the skin or emit strong fumes. Avoid mixing different cleaning products, as this can cause dangerous chemical reactions. When you’re pouring or diluting cleaning solutions, do it in a well-ventilated area and take care to avoid splashing.
  • Before you begin cleaning, locate and shut off the water supply valve connected to your toilet. This valve is typically located near the base of the toilet, either on the wall or the floor. Turning off the water supply prevents accidental flushing or overflowing of the tank as you clean it.
  • If you have an electrical outlet near the toilet tank, ensure it is kept dry during the cleaning process to prevent the risk of electric shock. Don’t use electrical appliances or devices near the water source.
  • To avoid any mishaps or exposure to cleaning chemicals, it’s best to keep children and pets out of the bathroom while you’re cleaning the toilet tank. Close the bathroom door until you’re done.

Gathering the Required Tools and Supplies

Here are some things you’ll need before you start cleaning your toilet tank.

  • Rubber Gloves: Invest in a good pair of rubber gloves to protect your hands from coming into direct contact with cleaning agents and potentially harmful bacteria. Choose gloves that fit well and provide a waterproof barrier.
  • Cleaning Solution: There are many options for cleaning solutions, depending on your preference. You can choose a commercial toilet bowl cleaner that contains disinfecting and descaling properties. Or you can opt for natural cleaning solutions like vinegar or baking soda, which are effective and environmentally friendly.
  • Bucket or Container: Have a bucket or container ready to collect water from the tank when draining it. This will prevent any spills and make the process more manageable. You’ll also need a bucket to mix the citric acid.
  • Citric Acid: It’s known to effectively kill bacteria, mildew, and mildew. Buy some powdered citric acid from the store as you’ll need it for the first cleaning method we’ll be showing you.
  • Cloth or Sponge: Keep a microfiber cloth or sponge handy for wiping down the tank’s exterior surfaces, including the lid and any other accessible parts.
  • Old Toothbrush: You can use an old toothbrush to reach tight corners, crevices, and hard-to-reach areas within the tank. It lets you scrub more precisely.

Mop, paper towels, or Rags: Have some paper towels or rags and a mop available to wipe up any spills, excess cleaning solution, or moisture that may occur during the cleaning process.

Method 1- Citric Acid Solution

If you don’t want to do any scrubbing at all, then this is your best bet. It basically involves only citric acid and warm water.

First, with a bucket grab some warm water from your tap, the water needs to be warm or hot because it does the job better than cold water.

Ensure the water is about the same amount that fills your tank on a good day. Pour out a large cup of your citric acid powder and add it to the warm water in the bucket. Stir.

Some people add the water directly to the tank first then add in the citric acid but this is more effective because stirring ensures all of it dissolves.

Drain all the water from your toilet tank, then pour in the citric acid mix. Ensure the water goes above all the dirt so it can get it all out.

(Ensure the window is open while you’re doing all this.)

Now we wait. Put the tank lid back and wait for 2-3 hours. When you come back, flush your toilet and you should see great results.

Of course, there’ll be some dirt left but you should be pretty satisfied with the results unless you’re willing to scrub the rest out.


Method 2- Vinegar Or Any Cleaning Agent

This method is a bit more complex, so here is a step-by-step guide to help you through the process:

Step 1- Shut off the water supply

Locate the water supply valve near the base of the toilet. Turn the valve clockwise until it is fully closed to stop the water flow. Flush the toilet once or twice to empty the tank of any remaining water.

Step 2- Drain the water from the tank

Place a bucket or container under the toilet tank’s fill valve or overflow tube. Next, open the fill valve or lift the overflow tube’s flap to allow the water to drain into the container. You can use towels or rags to soak up any excess water or spills.

Step 3- Remove mineral deposits and stains

Mix a cleaning solution by combining equal parts of vinegar and water in a spray bottle or container. Spray the solution generously onto the interior surfaces of the tank, focusing on areas with visible mineral deposits or stains. Allow the solution to sit for a few minutes to dissolve the deposits.

Step 4- Clean the tank’s interior surfaces

Scrub the interior surfaces of the tank using a scrub brush or toilet brush, paying attention to areas with stubborn buildup. For hard-to-reach corners or crevices, use an old toothbrush dipped in the cleaning solution. Scrub well to remove any remaining deposits or stains. If necessary, repeat the process or use a more concentrated cleaning solution for particularly stubborn stains.

Step 5- Clean the toilet tank lid and exterior

While the interior of the tank is soaking, remove the toilet tank lid. Then wipe the lid with a microfiber cloth or sponge dampened with the cleaning solution. Pay attention to any visible stains or grime. Clean the exterior surfaces of the tank using the same cloth or sponge and cleaning solution. Lastly, wipe down all accessible parts, including the top, sides, and bottom of the tank.

Step 6- Flush, rinse and finish up

Once you’ve thoroughly cleaned the tank’s interior and exterior, it’s time to flush and rinse. Turn on the water supply valve to allow water to fill the tank. Flush the toilet a few times to rinse away any remaining cleaning solution or residue. Check for any leaks or malfunctions during the flushing process.

Once the tank is filled with clean water, replace the toilet tank lid securely. Use a dry cloth or paper towels to wipe away any moisture or water droplets on the exterior surfaces. Dispose of any used cleaning materials properly.


Preventive Maintenance Tips

Cleaning your toilet tank is just one part of keeping it in tip-top shape. We’ll be sharing some tips that can help you extend the lifespan of your toilet, prevent future issues, and keep it functioning efficiently.

  • Establish a regular cleaning schedule for your toilet tank. Aim to clean it at least once every three to six months, or as needed based on usage and water quality.
  • When cleaning your toilet tank, opt for mild cleaning agents whenever possible. Natural alternatives like citric acid, vinegar, baking soda, or lemon juice can effectively clean and deodorize the tank without harsh chemicals. If you prefer commercial cleaners, choose those specifically formulated for toilet cleaning and follow the instructions carefully.
  • Harsh chemicals, like bleach or abrasive cleaners, can damage the toilet tank’s components and cause discoloration. If you must use a stronger cleaner, dilute it properly and use it sparingly.
  • The quality of water in your area can affect the cleanliness of your toilet tank. If you have hard water with high mineral content, consider using a water softener or installing a water filtration system to reduce mineral buildup.
  • Regularly check and replace the toilet tank’s fill valve if it becomes clogged or shows signs of mineral deposits. Periodically inspect the components of your toilet tank, such as the fill valve, flush valve, and flapper.
  • Consider installing a dual-flush mechanism or a low-flow toilet to reduce water usage per flush. Avoid flushing unnecessary items down the toilet, such as sanitary products or excessive toilet paper, as they can cause clogs and strain the flushing mechanism.
  • Teach everyone in your household about proper toilet usage and maintenance. Encourage them to avoid flushing items that can cause clogs, like cotton balls, dental floss, or paper towels.

Common Issues You Might Have With Your Tank

Despite regular maintenance, you may still have issues with your toilet tank. Understanding and troubleshooting these common problems can help you address them quickly and avoid further complications.

Here are some common issues and their possible solutions.

Constant Running Water

If you hear water running continuously in the toilet tank, then there’s a problem with the fill valve or flapper. Check if the flapper is properly sealing the flush valve. Adjust or replace it if necessary. Afterward, inspect the fill valve for any leaks or malfunctions. Clean or replace the fill valve if needed.

Weak or Incomplete Flush

If your toilet tank has a weak or incomplete flush, the flush valve or flapper may be the culprit. Make sure that the flapper is fully opening and closing when you flush. Adjust or replace it if it’s not functioning properly. Check the water level in the tank, it should be at the recommended level as specified by the manufacturer. If it’s not, adjust the float or fill valve to achieve the correct water level.

Leaking Tank

If you’re one to conserve water, then this can drive you crazy if you can’t find the source of the leak. A leaking toilet tank can waste water and potentially damage your bathroom floor. Check all the connections and seals within the tank. Tighten any loose connections or replace faulty seals. If the tank itself is cracked or damaged, you may need to replace it to stop the leak.

Mineral Buildup And Clogs

Over time, mineral deposits can accumulate in your toilet tank, leading to reduced water flow and clogs. You can use a descaling agent or a mixture of vinegar and water to dissolve mineral deposits. If a clog happens, use a plunger to try and clear it. For stubborn clogs, you may need to use a toilet auger or call a professional plumber.

Condensation On The Tank

If you notice excessive condensation on the outside of your toilet tank, it can happen because of temperature differences in the bathroom. If this happens, improve ventilation in the bathroom by using an exhaust fan or opening a window to reduce humidity levels.

Phantom Flushing

Phantom flushing refers to a situation where the toilet tank flushes and refills without anyone flushing it. This issue is often caused by a faulty flapper that doesn’t seal properly. Check if the flapper has any faults and be ready to replace it if necessary.

Weak Water Pressure

If you’re experiencing weak water pressure in the toilet tank, it may be due to a partially closed supply valve or a clogged water line. Ensure that the water supply valve is fully open then check for any obstructions or debris in the water line and clean or remove them if necessary.

Final Words

How long has it been since you cleaned your toilet tank? With this article, you can go ahead and check if your toilet tank is clean. By following the simple steps and suggestions above, you can ensure that your toilet tank is always in tip-top shape. Remember, regular checkups and prevention are always easier and more economical than fixing the problem.
