What causes yellow stains in the toilet bowl?

When speaking about public restrooms such as those located at shopping malls or gas stations, difficult-to-remove yellow stains in the toilet bowl are mostly a sign of neglect. Lack of due WC maintenance in our homes, on the other hand, is something out of the ordinary, as all of us understand the importance of keeping these tools clean and sanitary.

Still, there they are – yellow, nasty, frustrating spots that can make your bathroom time intolerable. But what’s causing them? Let us find out!

Here are the three most common factors contributing to the appearance of the pesky yellow stains in the toilet:

  • Urine residue accumulation leads to the formation of stains of pale yellow color. It is the work of a pigment called urochrome found in urine. The older the device is, the more imperfections its bowl surface has, and thus the easier it holds on to any coloring agent. Failing to properly flush/clean your toilet will result in such stains getting darker and more resistant to chemical removers;
  • Hard water. Sometimes, you can see a toilet stained yellow even if it is cleaned and flushed regularly. A yellow stain around the toilet base is limescale buildup; it forms on the toilet walls because of hard water rich in minerals, primarily calcium. Yellow limescale formations have a much more solid structure than regular urine stains. Moreover, lime buildup often ends up in drains, clogging your pipes and causing your toilet to back up;
  • UV-caused discoloration. Being exposed to sunlight for a long time can change the color of your toilet too. It is especially true for white plastic tool seats that are more prone to UV-caused yellow spotting than the bowl and the cistern made of porcelain.

How to get rid of yellow stains in the toilet bowl

As soon as you determine the source of your stains, it is time to begin cleaning. Firstly, it is wise to check your manufacturer’s instructions to know which products are safe to use in your situation. Certain chemicals contained in any commercial-grade toilet yellow stain remover can be too aggressive for the inner workings of your toilet or lead to the discoloration of plastic toilet seat parts.

Now, down to cleaning. Here is what you need to do to remove yellow stains from the toilet:

Step 1: Preparation

Prepare the materials you will use to clean your device. Shut down the water supply and remove excess water from the toilet bowl to facilitate the cleaning.

Step 2: Initial cleaning

Use a toilet brush and some disinfectant to scrub the area before you begin working on the tougher spots. General cleaning will help get milder staining out of the way and focus on the main task. Alternatively, consider giving your toilet a good overnight soak in white vinegar before scrubbing.

Step 3: Main cleaning

If you know what has caused the staining, you will be much better prepared to deal with the problem effectively. The following are some of the most helpful recipes for homemade stain removers that you can try right now, as most of the ingredients are easily found in any household:

Baking soda + vinegar

Carbonic acid, one of the two chemicals formed as the result of the reaction between baking soda and white vinegar, can help you remove all kinds of toilet stains, including mineral deposits inside your toilet.

Pour a cup of vinegar into your toilet bowl. Use a toilet brush to make sure the vinegar gets everywhere it needs to be. Next, after about 30-60 minutes, take the box of baking soda and scatter it all over your toilet so that it equally covers the entire surface, sticking to the vinegar.

Spray another cup of vinegar over the baking soda to trigger the fizzy reaction. Leave it for 15 minutes, at least, after which scrub the surface with a toilet brush before rinsing.


While it is not an obvious choice of a toilet stain remover, coke has proven to be an excellent solution for challenging urine residue accumulation and hard water stains. It is so effective that it sometimes allows you to entirely avoid scrubbing.

Flush the toilet and cut off the water supply. When the bowl is nearly empty, pour in up to 5 liters of Coca-Cola. Let it sit there for at least a few hours or – better yet – leave it overnight. Flush generously and use a toilet brush if any residue remains.

Vinegar + Borax

The mixture of borax and vinegar is great for eliminating severe mineral deposits. If your toilet stains did not budge after you applied baking soda and vinegar, switching bicarb with Borax is the next logical step to take.

After flushing the toilet, throw in 1/4 of a cup of Borax and scatter it around with your toilet brush until it covers the entire interior surface of the bowl. Then, add two cups of white vinegar and leave the resulting mixture to rest there for around half an hour. Finally, scrub the stains intensely and rinse the toilet a few times.

How to prevent yellow spots on the toilet

Now that you know how stressful and tiring removing yellow stains from the toilet can be from your experience, it is best not to let things go that far and focus on preventing rather than treating. It is critical to always have a clean toilet.

That involves washing and scrubbing it with cleaning chemicals or homemade remedies on a regular basis to keep yellow stains at bay. It might seem like too much trouble at first, but it will bring good dividends in the long run.

Here are a few vital toilet stain prevention tips to keep in mind that will make your life so much easier:

  1. Do not give urine a chance to stain your toilet. If there are any splashes, they need to be removed at once.
  2. Beware of the toilet plume: do not forget to close the lid when you flush. Use a rag to wipe down the exterior after each time on the toilet.
  3. To keep the toilet fresh and spotless, use chlorine tablets regularly.
  4. Avoid using abrasive tools like pumice stones and toilet brushes with extra hard bristles. It can inflict cracks and dents on the bowl surface, and urine pigmentation will stain easier.
  5. Use chemical detergents to disinfect the seat at least once a week.
