What causes yellow stains in bathtub, sink, shower, and toilet bowl?
When people see yellow stains in their bathtubs, they get surprised because they clean these areas often.
What they don’t know is that the yellowing is likely to keep occurring unless they find the cause. So in this section, we shall talk about some of the main causes of yellow stains in bathtub, sink, toilet, and shower.
1. Hard water
As aforementioned, hard water is the main culprit of the yellow stains in the tub, toilet, or sink.
If you live in a hard water area, this is something you cannot easily prevent.
The yellowing is due to the high concentration of minerals like calcium, magnesium, and iron in the hard water.
There is no doubt that the yellow stains caused by mineral deposits or build-up can be difficult to get rid of. However, with the right products, as discussed in the next section, you can easily restore the shiny appearance of your tub.
If you are not sure whether your water is soft or hard, try this simple test.
Add a few drops of pure liquid soap into a bottle of water. Shake for a few seconds and check the appearance of the water. If it is cloudy, then you have hard water.
Alternatively, take a sample of your water to be tested by a state-certified laboratory in your area.
2. Tannins in the water
Tannins are decayed organic matter that finds its way into the water.
Although tannins are not considered harmful, they give water a yellowish color and an unpleasant odor.
As a result, they stain laundry as well as cause yellow stains in the tub, sink, toilet, and shower.
The most effective way of removing tannins from water is by filtration, which we shall talk about in the next section in this article.
Prior to doing this, you need to determine whether or not the yellow stains on your tub are due to tannins.
Simply fill a glass with water and let it sit overnight. You will confirm that the water contains tannins if the color intensity remains the same without settling at the bottom.
3. Iron in the water
Most water systems have iron.
However, if the quantity of iron is more than the recommended amount, it leads to rust.
Rust occurs when iron mixes with oxygen in the water.
You can tell there is rust if you notice a yellow, red, or orange tint in the water, which stains your tub, sink, toilet, and fixtures.
Unlike tannins, rust does not give the water an unpleasant taste or odor.

4. Oil accumulation from bath products
You may say that you don’t use oil in the bathroom, but the products you use might contain oil. For instance, lotion and hair cream might find their way into the tub as you take a shower.
Also, if you use the oil products near the sink or wash your face or hands in the sink, the oil will build up over time and cause stains.
The solution is to ensure you clean the tub and sink after every use with the appropriate products that will remove the oil.
How to remove yellow stains from bathtub and other surfaces
The most suitable way to get rid of yellow stains in tubs or surfaces depends on which type of mineral is causing the stains.
Also, it depends on the products you like using and what you can afford.
In this regard, readily available household products like vinegar, lemon, and baking soda are perfect for cleaning various surfaces.
1. White vinegar
If you have used all cleaning agents without success, try white vinegar. Pour a little white vinegar onto the yellow stained area, then scrub using a brush.
You can also put the white vinegar into a spray bottle, spray the stained area, wipe with a cloth or rag, and rinse it off.
For stubborn stains, repeat the process until the stain comes out.
White vinegar is perfect for removing stains on delicate surfaces like an acrylic tub.
2. Baking soda
Baking soda is a household product that is readily available.
If white vinegar fails to remove the yellow stain, try baking soda.
You can mix it with water or with hydrogen peroxide.
When using water, mix one-quarter of baking soda with 50ml of warm water.
For hydrogen peroxide, use the ratio 2:1. For instance, mix 2 teaspoons of baking soda with one teaspoon of hydrogen peroxide.
After mixing, apply the paste to the stained area and leave it for 15 minutes. Then, use a scouring sponge to scrub the area and rinse off with clean water.
Keep doing it until the surface is clean.
3. Salt with lemon
Salt with lemon juice is a cost-effective natural remedy used to dissolve mineral deposits on stained surfaces at home.
Simply mix salt and lemon juice, and then apply the mixture on the affected surface with a sponge.
Wait for a few minutes and scrub off the stains and then rinse with clean water.
4. Scrub using whitening toothpaste with a toothbrush
In one of the home cleaning forums, someone suggested using whitening toothpaste with a toothbrush to scrub off the yellow stains.
I don’t know how well this technique works but cleaning experts argue that whitening toothpaste has mild abrasives. This means that it can help to remove certain stains on surfaces.
Its application is quite straight forward.
Simply apply the whitening toothpaste to the stained area then use a toothbrush to scrub the yellow stains off.
5. Cleaners for hard water stains
Finally, if all the above household products fail to work, you might have to consider using cleaners designed for hard water stains.
For instance, Bar Keepers Friend Cleanser and Polish comes highly recommended.
Bar Keepers Cleanser is a multi-purpose cleaner that cleans all surfaces including ceramic, glass, marble, stainless steel, and brass.
It is very effective at removing stains in a tub, toilet, or sinks as it uses natural acids such as oxalic acid, which safe on ceramic.
To remove the stain, sprinkle the powder on the stained surface with a bit of water and scrub off with a soft brush.

A water softener helps solve the hard water challenges.
As aforementioned, hard water causes yellow stains on ceramic surfaces.
But if you add a water softener to it, you will say bye to yellow stains and save your energy, time, and money.

This is the perfect solution for filtering out tannins, removing excess iron, manganese, and other harmful products in your water.
