How to Remove Rust Stains from Toilet?

Remove rust stains form toilet

Rust stains in a toilet look pretty awful, and besides this, they are tough to clean. Bathtubs, sinks, commode all are made out of porcelain. Porcelain is rust-resistant, but the metal attached to it is usually not. I have personally experimented with some stuff, and I will be sharing that with you.

How to remove rust stains from toilet? To remove rust stains from the toilet; firstly, start with using household items like vinegar, baking soda, lemon, or harpic powerplus. These will remove mildly rusted stains. It is best to have commercial removers like CLR PRO, Iron OUT, POR-15 40701 Rust Remover for heavily rusted surfaces. Some may need scrubbing with an abrasive material like a pumice stick and shaws pad.

Rusty toilet is not uncommon, despite stainless steel piping we still often encounter them. This is due to deposits of salts, mainly calcium. These salts not only destroy the aesthetics but also prone the piping to leakages. Therefore this needs to be addressed properly.

A. Household methods to Remove Rust Stains from Toilet

Household methods to remove rust stains from toilet are an easy and affordable alternative to expensive and unconventional industrial grade rust removers. I prefer to use household products for mild to moderate rusts and only jump to industrial-grade removers for heavily rusted stains.

Below I have elaborated the methods.

1. Vinegar and Baking Soda to Remove Rust Stains from Toilet

Vinegar and Baking Soda

Vinegar, if left for long on rusty surfaces, removes the stains very well. But vinegar can’t stay on incline surfaces for long. To solve this problem, we need to sprinkle baking soda over it. The method is pretty simple:

  1. Make sure to dry out the surface. Drain water from the tank and mop walls dry with a piece of cloth.
  2. Spray white vinegar on the rusty surface, and then sprinkle baking soda over the vinegar. Spray a second layer of vinegar over the baking soda. This will help retain vinegar better.
  3. For better results, I recommend waiting for few hours.
  4. Now using Aluminum foil, make a ball out of it and scrub the stains with it. You can also use steel wool for the same purpose.
  5. Wash the surface with water and make sure to dry it out.
  6. Repeat the process if necessary.

2. Baking Soda and Lemon Juice to Remove Rust Stains from Toilet

Baking Soda and Lemon

Lemon juice contains citric acid in good quantities. Making a paste of it and baking soda can be handy for removing rust stains from the toilet. Although heavy stains can be difficult to remove, a steel-wired brush can make the job easy. The steps are simple:

  1. Squeeze freshly cut lemons for juice in quantities sufficient for the project.
  2. Add equal quantities of baking soda to make a thick paste out of it.
  3. Please make sure the surface is dry, and then apply the paste onto it.
  4. Preferably wait overnight and then scrub the surface with a steel wire brush or aluminum foil.
  5. Wash the surface with water.
