How To Get Rid Of Blue Toilet Water? (This Trick Works)

Does your toilet water look blue? It’s tempting to ignore it, but the longer you leave it, the harder it will be to eliminate that blue tint.

Over time, the blue tint can seep into the rest of your toilet and show up in other places. 

You can remove this coloration and restore your toilet to its normal state before it gets out of hand! Here’s how you can get rid of blue toilet water and keep your toilet looking new!

You can get rid of blue toilet water in several ways, but the most common way is using a mild toilet cleaner and scrubbing with a brush to get rid of the blue toilet water. You can also use white vinegar with baking soda to scrub the toilet. Doing this helps to remove the stain before it becomes permanent.

Why Does My Toilet Water Turn Blue?

How to Get Rid of Blue Toilet Water

There are a few reasons why your toilet water might turn blue. Below are the possible causes of your toilet water being blue.

#1. Cleaning Your Toilet Bowl with Bleach

If you clean your toilet with bleach, it can turn your toilet water blue. The blue toilet water is from a chemical interaction between cleaning chemicals and toilet water.

It is due to using blue cleaning tablets or bleach- or chemical-based toilet bowl cleaner. The bleach’s chemicals give the toilet its blue color if they come in contact with water.

Unfortunately, the chemicals can stain the toilet bowl if you use the blue bleach more often than its producers recommend.

#2. Copper in the Water

If there are high traces of copper in the water, it can lead to you having blue toilet water. It’s because copper dissolves more easily in acidic water; it’s higher in acidic areas.

If you have low copper in your water and still have blue toilet water, it’s likely copper pipe corrosion. Copper oxidizes to develop a blue-green patina.

If there isn’t much trace of copper in your water, but your toilet water is blue, there may be a leak in your pipe, which the copper corrosion passes through, and mineral deposits are leaking, resulting in blue toilet water. It’s best to call a plumber to fix this issue for you.

#3. Water Treatment

The blue color comes from how you treat your water. In the hot weather, some cities add more chlorine to the water when there is a chance of water contamination. When this water mixes with the toilet chemicals, the water turns blue.

#4. Dye

Blue toilet water could be due to the dye that follows the water through the pipes. So if your toilet bowl is stained blue, the dye has saturated.

If you notice that your toilet water has turned blue, don’t panic. It doesn’t mean that you have mold in your toilet bowl or that something has gone wrong with your plumbing.

However, chances are it’s one of these reasons, and if so, there are a few things you can do about it.

Seven Ways to Get Rid of Blue Toilet Water

There are a few ways to remove the blue in your toilet water and restore it to its shiny white color.

In the table below are some ways to do that.

How Long Does Blue Toilet Water Last?

The blue toilet water should last as long as the cleaning or coloring product. Most dyes can be used for four weeks before they need to be changed; when the color begins to fade, you can also tell it needs to be changed.

Most dyed products show when they need to be changed. You should call a plumber if the blue water isn’t from the dye but a corroded copper pipe.

Most people think that blue toilet water lasts forever, but the truth is that it only lasts for a few days.

After that, the blue color starts to fade, and the water becomes clear again. So the best way to get rid of blue toilet water is to flush it away. 

The exact time depends on several factors, such as how many people are using your toilet, what you’re doing there, and how hard you flush.

Anything that lowers water pressure or slows down water flow through your pipes can extend how long blue toilet water remains in your bowl.

How Can I Change the Color of My Toilet Water?

All you have to do to change the color of your toilet water is put a few drops of dye in the water of your toilet tank.

If you see an evident change in the water’s color but don’t use it excessively, you could accidentally dye the tank or bowl of your toilet.

You can change the color of your toilet water to any color you want with a few simple steps. First, you’ll need to purchase some food coloring.

Next, add a few drops of food coloring to the water in your toilet bowl. Then, use a toilet brush to swirl the water around until it’s evenly mixed. Finally, flush the toilet and enjoy your new colorful creation!

Making your toilet water any color you want is a great way to change its look and make it match your bathroom décor.

For example, white toilet water will match a bathroom with white walls and other light-colored furnishings.

Yellow toilet water, however, will match well with a bathroom with yellow walls and similar coloring.

If you’re struggling to decide which color you’d like your toilet water, it might be easiest to try a few different options.

Is Blue Toilet Water Dangerous?

No one should drink blue toilet water, not you, your pet, or your child. If you have children or pets, avoid toilet-water-changing cleaners.

If the toilet is blue from copper, your family risks exposure to too much copper. Test your water for copper, as copper toxicity damages organs.

If your toilet water is blue, and it isn’t a result of copper contamination, if it’s a result of a cleaning agent, it may be unsightly, but it isn’t harmful.

It will only cause permanent damage to the toilet bowl if left for so long. Blue toilet water isn’t good for the environment if it’s a result of bleach.

Bleach kills bacteria, including helpful bacteria required to break down biodegradable material, causing blue toilet water.

It is a big problem if you have a septic tank; also, leftover bleach in toilets can damage the porcelain and break down the contents in the tank.

The best way to prevent blue toilet water is to avoid products that contain blue dyes. The easiest way is to use white vinegar as a toilet bowl cleaner.

(While we’re at it, you can make your vinegar-based all-purpose cleaner.) Vinegar has a variety of uses around your home and is environmentally friendly.

In addition, it can dissolve many stains and odors in your bathroom or anywhere in your house.


The dyes you put in the toilet are often to blame when the water in the toilet is blue.

It’s best to get rid of it before it becomes permanent; you can do that with household items like white vinegar and scrub the bowl with a brush.

There are also other ways to eliminate this color without breaking the bank.
