Main Reasons Your Toilet Seat Turned Blue

Here is why your toilet is turning blue. Spoiler alert! It’s not because your toilet is feeling a little sad. It’s likely due to chemistry or a brand new pair of blue jeans. 

What Does it Mean When Your Toilet Seat Turns Blue?

There are several reasons your toilet seat might turn blue such as blue jeans, prenatal vitamins, a rare condition named Chromhidroiss, and pregnancy. The least serious reason is that your new jeans have rubbed their color off on you.

The first and probably most common reason for a blue toilet seat is new blue jeans. If the jeans you have bought are brand spanking new, there’s a possibility that the dye from your jeans has bled onto your legs and then got on the toilet seat.

Another common reason for a blue toilet seat is pregnancy hormones. When a woman is pregnant, she produces more of the hormones estrogen and progesterone.

When these hormones mix with the materials that make up the toilet seat and the antibacterial coating, it can cause a chemical reaction that turns the toilet seat blue.

Why is My Toilet Seat Turning Blue?

The more common reasons for a blue toilet seat are dye stains from new blue jeans or the hormones estrogen and progesterone, which are heightened by pregnancy. Other reasons could include prenatal vitamins, Chromhidroiss, and Pseudochromhidrosis.

An additional reason that your toilet seat has turned blue is a certain ingredient in prenatal vitamins.

These vitamins include more folic acid than regular vitamins, which could make this strange phenomenon happen. However, this is only a theory and hasn’t been proven by scientists. 

A rarer reason for a blue toilet seat is a condition called Chromhidrosis. This is a rare disorder where the material Lipofuscin is produced more than the average person. 

The extra blue pigmented material in cells is expelled through sweat. This would cause your sweat to become blue which may explain the blue toilet seat. 

Another condition that can cause your toilet seat to turn blue is Pseudochromhidrosis. Exactly as it sounds, this condition acts like Chromhidrosis, thus having the same symptoms but for a different reason. 

This condition results from your body reacting to possible bacteria, fungi, chemicals, or dyes on your toilet seat, resulting in your sweat becoming blue, red, or black.

This is extremely rare but well known.

Why Would My Toilet Seat Turn Blue?

Pregnancy hormones, blue jeans, and rare conditions are all things that can be involved in your toilet seat turning blue. The most common reasons for this strange event are new blue jeans and pregnancy hormones.

Another possible reason could be because of rare conditions called Chromhidrosis or Pseudochromhidrosis.

It could also be an ingredient in prenatal vitamins, but scientists haven’t proven this theory. 

Does Bleach Stain Toilet Seats?

Bleach can cause stains on toilet seats. These stains are normally yellow and cannot be removed. However, this depends on the material the toilet seat is made out of. If a toilet seat is made out of porcelain-enameled material, then using bleach provides a high risk of stains on your toilet seat.

Although, if your toilet seat is made out of fireclay or just porcelain, then you won’t need to worry about bleach stains on your toilet seat.

When using bleach to clean surfaces, proceed with caution and wear gloves to protect yourself.

Does Bleach Damage a Plastic Toilet Seat?

Bleach will damage a plastic toilet seat over time. Many people have reported their plastic toilet seats turning yellow and peeling after many cleanings with bleach. However, this is a controversial opinion, with several people reporting no issues using bleach to clean a toilet seat. 

People have experienced flushing issues when using bleach to clean a porcelain toilet seat. Bleach can damage porcelain more than plastic.

Be sure to know what your toilet seat is made of before cleaning.

What is Chromhidrosis?

Chromhidrosis is a rare condition that results in pigmented sweat of any color being expelled from your pores. This is caused by an excess of lipofuscin or more oxidized lipofuscin in an individual. 

Chromhidrosis is a chronic condition, but the sweat’s pigment can decrease over time. 

The main symptom of Chromhidrosis is colored sweat. The sweat can be black, green, blue, brown, or yellow. Patients can also feel a strange prickling sensation before the sweat occurs. 

What are The Three Types of Chromhidrosis?

The three types of Chromhidrosis are Apocrine Chromhidrosis, Eccrine Chromhidrosis, and Psuedochromhidrosis. Apocrine Chromhidrosis affects the apocrine glands. Eccrine Chromhidrosis affects eccrine sweat glands. Psuedochromhidrosis mimics the symptoms of Chromhidrosis but is caused by dyes, chemicals, or pigmented bacteria.

The apocrine glands are located at the torso, eyelids, scalp, ears, and areola. The eccrine glands are widely located throughout the body.

In Psuedochromhidrosis, pigmented bacteria, dyes, or chemicals come in contact with eccrine sweat to form a sweat with a different color.

What is Pseudochromhidrosis?

Pseudochromhidrosis is when sweat without color mixes with colored bacteria, dyes, or chemicals to create colored sweat. It can also happen when fungi come in contact with the skin. It can affect any area of the body. 

Pseudochromhidrosis has the same symptoms as Chromhidrosis but isn’t the same thing. Chromhidrosis is started by chemicals in the body, whereas Pseudochromhidrosis is affected many materials outside the body. 

Can My Jeans Result in Turning My Toilet Seat Blue?

Blue jeans can result in your toilet seat turning blue. The dye from brand new jeans can rub off onto your legs and leave remains of the dye on the toilet seat. The dye has more of a chance of leaking if they are wet.

Be sure to thoroughly examine your jeans before assuming you have some rare condition, as this is a much more common explanation.

To remove this dye, put some rubbing alcohol on some toilet paper and scrub. 

Can Hormonal Changes Cause My Toilet Seat to Turn Blue?

Hormonal changes can cause toilet seats to turn blue. If a woman has higher levels of estrogen and progesterone, these hormones can react with the seat’s material and the antibacterial sealant turning the seat blue. 

Estrogen and Progesterone are produced at higher levels when a woman is pregnant. A blue toilet seat can indicate that someone is pregnant.

This is because these hormones can react with its materials which causes a reaction to turn the seat blue. 

However, this is not very common so think about the other possible reasons before turning to this one.

Is a Blue Toilet Seat a Sign of Pregnancy?

A blue toilet seat is not a direct sign of pregnancy. There are a variety of reasons for your toilet seat turning blue. Although, it can be a signal that a woman is pregnant because a toilet seat can be turned blue by reacting with the hormones Estrogen and Progesterone.

The hormones Estrogen and Progesterone are produced at high levels in a pregnant woman. So, if your toilet seat does turn blue, it could indicate that you are pregnant. 

However, there could be more reasons why your toilet seat has turned blue, so make sure to research those before jumping to this conclusion.

Your toilet seat turning blue is not a sign of diabetes. If you have a lot of mold and mildew that grows in your toilet, that can be a sign of diabetes. This is because people with diabetes have higher levels of glucose in their urine, known for feeding mildew.
