4 Types of Bathtub Stains And Removing Solutions

Getting the perfect soak means having a clean and comfortable bathtub. However, regular use, exposure to various substances, and lack of maintenance can lead to different types of bathtub stains, affecting both the look and hygiene of your bathroom. Here, we dive into the world of bathroom blemishes to arm you with knowledge on how to keep your tub pristine.

Types of Bathtub Stains

Hard Water Stains

Hard water stains are one of the most common types of bathtub stains. They are caused by mineral deposits like calcium and magnesium that are found in hard water. Over time, these minerals build up on the surface of your bathtub, leaving behind white, chalky deposits that can be difficult to remove.

Hard water stains start as small spots but can eventually cover large areas of your tub. They make the bathtub look dingy and dirty, even right after cleaning. The porous surface of the bathtub allows the minerals to sink in deeply, making these stains stubborn. Hard scrubbing with bathroom cleaners may lighten them somewhat, but fully removing hard water stains requires special removal products.

Soap Scum Stains

Soap scum stains are residue left behind from bathing. When soap combines with the minerals in hard water, it creates a filmy, sticky substance that clings to the bathtub. Soap scum appears as a cloudy, whitish layer that coats the bottom and sides of the tub.

Soap scum stains are most noticeable after showering, when the residue is still wet. As it dries, it hardens into a stubborn buildup. Soap scum accumulates over time, stealing the shine and glossiness from your bathtub. It also makes surfaces feel grimy.

Regular cleaning with an abrasive cleaner can help minimize soap scum. However, removing established stains requires dissolving the sticky film with ingredients like vinegar or ammonia. Scrubbing with a soft cloth or sponge will lift off the dissolved scum.

Mold and Mildew Stains

Mold and mildew stains occur in bathrooms that are prone to dampness. The warm, wet conditions allow mold spores floating in the air to take hold and multiply. In the bathtub, mold forms dark blotchy stains. The stains may be black, brown, orange, green or even pink or purple.

Mold stains start in tiny spots, but can grow to cover entire surfaces if left untreated. Mildew has a distinctive musty odor and can be slippery. Breathing in mold spores can cause allergic reactions or illness.

Eliminating excess moisture prevents mold growth. Bleach-based cleaners kill and remove existing mildew stains. Reoccurring mold may mean there are moisture problems that need to be addressed.

Rust Stains

Rust stains in the bathtub have a reddish-brown color and are caused by iron contaminants in the water or corrosion of metal fixtures. Iron in the water supply can leave behind rusty residues. Metal components in the tub, sink and pipes can also corrode and cause rust stains.

Rust appears as splotchy deposits or discoloration. The stains may be small at first but can spread if the cause is ongoing corrosion. Rust can permanently stain and eat away at surfaces over time.

Filtering devices can remove iron from water before it reaches your bathroom. Cleaning rust off quickly and protecting metal fixtures from corrosion will prevent permanent damage. Stubborn rust stains may need special removers or scrubbing with very fine abrasives.
