You've probably heard the expression "bathroom humor." However, there is nothing funny about a dirty toilet. A toilet with rusty stains around its bowl is one of the most eye-sore. Even if everything else in the bathroom is spotless, rusty streaks can cause problems for guests and household members.

What is the cause of rusty stains on toilets?

Rusty stains on the toilet bowl are usually an indicator of higher iron levels in the water supply. Although this may not be a problem, iron particles can oxidize to create a distinctive red-brown color. Old pipes may have iron in them, especially if they are deteriorating.

How to remove rust stains

Rust stains on a toilet bowl are easy to remove unless you have a very upset stomach. Use the right cleaning products.

• Bleach is not recommended as it can worsen the rust stain.
• Avoid using an abrasive scrubber as it could scratch the porcelain surface.
• Make your own cleaning solution. Use 1-part vinegar and 1-part water to spray or 3-parts baking soda and 1-part vinegar to make a paste.
• To scrub your bowl, use a non-abrasive toilet brush or scouring toothbrush.
• Wear proper safety gear, such as goggles and rubber gloves.
• To remove the majority of the water in the bowl, turn off the water supply.
• Try commercial cleaning products like Borax or Bar Keepers Friend to remove stubborn rust stains.

Upgrading your plumbing

While cleaning is essential to keep your toilet rust-free and free from iron, it won't solve the problem of iron in the water. You may need to replace parts of your plumbing system in order to prevent staining from occurring.

Replacing iron pipes with copper or PEX piping

• To filter iron and other particles from the water supply, you can add a water filtration device.
• To remove various minerals, install a water softener.
