You’ve come to the right place if you struggle with those stains. Keep reading to learn how to remove blue toilet cleaner stains.

What Causes Blue Toilet Cleaner Stains

It’s an achievement unlocked when you have finally cleaned up your toilet bowl, but it’s a bit frustrating when you see those stains even when you have cleaned it all up.

The most common stains in bathrooms are blackish and brownish when too much iron is in the water. On the other hand, too much calcium in the water causes the toilet to appear yellowish and whitish.

If you see your toilet bowl greenish or bluish, there are two reasons: copper or residue from blue toilet cleaners. Now, let’s talk about how these stains show up, what causes them, and why they appear blue (and sometimes green).

Presence of Copper in the Water

The high content of copper in your toilet water can be caused either by the water source itself or by your plumbing system’s deteriorating pipes.

Residue from Blue Toilet Cleaner

Blue dyes, added to most toilet bowl cleaners, are the most common cause of blue stains in toilets. The best indicator that a cleaner will likely leave stains is its bright blue color. You’ll want to avoid touching it with your bare hands or mixing it with other cleaners.

If you have double-checked that your water supply is free from any corrosion, or has no trace of any copper content, then this cause could be the one to blame.

What to Use to Remove Blue Toilet Cleaner Stains

Here are some cleaners and ingredients to dissolve those blue stains in your toilet bowl.


Bleach is pretty potent and has a strong odor, so it’s not advised to use it around children or if you have a respiratory condition. Besides that, it’s a solid option for cleaning toilet bowls because it kills unwanted odors.

Not to mention, it dissolves the blue color like a champ. Remove the blue stains by pouring bleach on the toilet bowl, then scrub and flush it off.


Any rubbing alcohol with a 70% solution works well for removing stains. You need a bowl with a dry inner surrounding and set to go.

Soak some toilet paper in alcohol and stick them to the toilet bowl.
Let them sit there for a few minutes before scrubbing the bowl with a brush. You may do this as often as needed until the stains are removed.


Like bleach, ammonia should be used cautiously because it has a strong odor. It’s also not recommended to touch it because it can cause itching.

To remove the blue stains, mix a cup of ammonia with water. Then, pour it into the toilet bowl and let it sit for a few minutes. Scrub with a brush if needed, then flush the bowl to rinse off thoroughly.

Magic Eraser

A Magic Eraser is another good product that can remove blue spots in the toilet.

You must wet and scrub it against the bowl like a typical eraser. Let it sit there overnight, and flush it the next day to rinse.

Baking Soda and Vinegar

Using baking soda for cleaning is a cheap and easy way to end up with a shiny surface. It’s most effective in removing stains when mixed with a cup or two of vinegar.

Let the mixture stay in the toilet bowl for at least 15 minutes before flushing it away.


Nope, this isn’t a joke. Coca-Cola is a pretty efficient cleaner for toilet bowls because of its acidic content. It dissolves stains like a champ, and it’s a lifesaver when you don’t have any detergents around and can’t run to the store.

You must pour a can of Coca-Cola into your toilet bowl, scrub the stains off, and then flush it.

3 Ways to Prevent Blue Toilet Cleaner Stains

Getting rid of stains in your toilet is a real challenge, but preventing your toilet from having them is manageable and accessible. Try some simple tips to maintain a stain-free, sparkling-clean toilet bowl.

Regular Cleaning

You have to set a schedule for thorough cleaning of your toilet bowl. Make sure to clean the toilet bowl using a brush every 2 to 3 days, especially when the toilet is shared with kids and adults. It prevents the build-up of any stains.

Monthly Scrubbing

With the help of the cleaning power of vinegar, scrub your toilet bowl every month. Vinegar prevents any water rings and blue stain residue from appearing and cleaning the toilet monthly will keep it fresh and prevent stubborn odors from developing.

Tank Cleaning Twice a Year

A water tank full of dirt will lead to a rusty and stained bowl. It doesn’t have to be cleaned frequently; only once every six months will suffice.
Simply fill the tank with vinegar and let it sit for at least 12 hours. Once done, flush it out and scrub the remaining residues out of the tank.

Pro Tip! How to Get Blue Toilet Cleaner off Hands

If you wonder how to remove blue toilet cleaner stains from your hands, use white vinegar or lemon juice and baking soda as abrasive. Then rinse with soap and warm water.

Final Thoughts

Getting blue stains on your toilet is a problem. It is not hard to learn how to remove blue toilet cleaner stains as long as you have any of the household cleaners mentioned above. However, it can be manageable and easy to prevent once you know the source of these stains.
