How To Get Rid of Yellow Stains in Bathtubs?


Created At 1 year ago


Mineral deposits present in the water left behind by hard water can produce stubborn stains in your bathtub, which are an eyesore. What’s in your water will determine the hue of the stain. Here is the complete guide on how to get rid of yellow stains in bathtubs no matter what’s creating them. A bathtub with yellowish streaks is unattractive. Taking a bath makes most people feel unpleasant, and it’s also highly unwelcoming to visitors.

Why Yellow Stains Occur in Bathtubs?

People are startled to find yellow stains in their bathtubs since they clean these areas often. They don’t realize that unless they figure out what’s causing the yellowing, it’ll keep happening. So, we’ll discuss and go through some of the most common causes of yellow stains in the bathtub, sink, toilet, and shower in this section.

Hard Water

Hard water, as previously said, is the primary cause of yellow stains in the tub, toilet, or sink. It is something you can’t simply avoid if you reside in a hard water location. The yellowing is caused by the hard water’s high concentration of calcium, magnesium, and iron.

There’s no denying that mineral deposits or buildup can leave yellow stains that are tough to remove. You may restore the gleaming beauty of your tub with the appropriate materials, as detailed in the following section.

Try this simple test if you’re not sure if your water is soft or hard. In a bottle of water, sprinkle a few drops of pure liquid soap. Check the look of the water after shaking for a few seconds. You have hard water if it is hazy. Alternatively, you may send a sample of your water to a state-certified laboratory in your region to be analyzed.


Tannins are organic stuff that has decomposed and found its way into the water. Although tannins are not toxic, they cause water to become yellow and have an unpleasant odor. As a result, they leave yellow stains in the tub, sink, toilet, shower, and clothes.

You must first evaluate whether or not tannins cause the yellow stains on your tub. Fill a glass halfway with water and set it aside overnight. If the color intensity remains constant without sinking to the bottom, you may be sure the water contains tannins.

The Presence of Iron in Water

Iron is present in most water systems. Rust occurs when the amount of iron consumed exceeds the acceptable level. When iron reacts with oxygen in water, it forms rust. If the water has a yellow, red, or orange tinge and stains your tub, sink, toilet, and fittings, you have rust. Unlike tannins, rust does not provide a disagreeable flavor or odor to the water.

Bath Products Can Cause Oil Buildup

Even though you claim not to use oil in the bathroom, the items you use may include oil. When you take a shower, lotion and hair cream, for example, may make their way into the tub.

Additionally, if you use oil products near the sink or wash your face or hands in the sink, the oil will build up and produce stains over time. The answer is to make sure you clean the tub and sink after each usage with proper oil-removal solutions. The best method for removing yellow stains from tubs or surfaces is determined by the type of mineral generating the spots.

It also depends on the items you like to use and your budget. In this case, everyday home items like vinegar, lemon, and baking soda are ideal for cleaning various surfaces.

Cleaning Methods for Cleaning Yellow Stains in Bathtub

White Vinegar

If all other cleaning solutions have failed, try white vinegar. Apply a small amount of good-quality white vinegar to the yellowed region and scrape with a brush. You may also use a decent spray bottle to apply the white vinegar to the discolored area, then wipe it off with a towel or rag before rinsing it off. Repeat the technique for persistent stains until the stain disappears. White vinegar is ideal for eliminating stains from sensitive surfaces such as an acrylic tub.

Baking Soda

Baking soda is a most common and perfect home item that is easy to get by. Try baking soda if white vinegar fails to remove the yellow stain. It mixes with either water or hydrogen peroxide. Mix one-quarter cup baking soda with 50 ml warm water when using water.

Use a 2:1 ratio for hydrogen peroxide. Mix two teaspoons baking soda with one teaspoon hydrogen peroxide, for example. Scrub the area with a scouring sponge, then rinse with clean water. Apply the paste to the discolored area once it has been mixed and set aside for 15 minutes. Continue doing so until the surface is apparent.

Lemon and Salt

The combination of salt and lemon juice is a cost-effective natural treatment for removing mineral deposits from discolored surfaces at home. Combine salt and lemon juice, then sponge the mixture over the afflicted area. Wait a few minutes before scrubbing away the spots and rinsing with clean water.


Someone recommended scrubbing the yellow spots with whitening toothpaste and a toothbrush on one of the home cleaning sites. We are not sure how effective this method is. It implies it can assist in the removal of some stains from surfaces. However, cleaning professionals claim that whitening toothpaste contains light abrasives.

Its implementation is simple. Apply the whitening toothpaste to the affected area and scrape the yellow spots away with a toothbrush.

Stain removers for hard water

Finally, if none of those mentioned above home items works, you may need to buy cleansers intended for hard water stains. Because it utilizes natural acids like oxalic acid, which is safe on porcelain, it is highly efficient at eliminating stains in a tub, toilet, or sink. Sprinkle the powder over the affected area with a bit of water and scrub with a soft brush to remove the stain.
