For example, applying white vinegar or lemon juice and scrubbing with a toilet brush typically works on newer stains. You can also try mixing white vinegar and baking soda if you need a stronger scrub. For older stains, using an industrial-strength cleaner like CLR should do the trick.
Pour a cup of vinegar into the bowl, then mix it around with a toilet brush. Add a cup of baking soda to the coated areas and immediately follow up by adding another cup of vinegar. Wait about 10 minutes to allow the baking soda and vinegar to interact, creating that effective fizzing action.
Simply sprinkle baking soda on the stains and scrub with a brush. Use bleach: Bleach is a powerful cleaning agent that can quickly remove stains. However, it should be used sparingly as it can damage the porcelain on toilet bowls. Apply bleach to the stains and let it sit for several minutes before rinsing away.
A much better solution is to use some WD-40 Multi-Use Product. Most people don't know that WD-40 can solve many of their household cleaning needs quickly and easily. When cleaning a toilet bowl, WD-40 works by softening the rust and lime deposits, so they can be easily wiped away. You don't need to use much of it.
The brown stains in your toilet aren't what you think - they're bits of limescale! You aren't doing anything wrong in your cleaning regime; these deposits are caused by hard water.
Make a paste by mixing 1/2 cup of Borax and enough vinegar to form a thick paste. Spread the paste immediately onto the hard water stains in the toilet so they are completely covered by the paste. The Borax will harden quickly so don't add the vinegar until you are ready to apply the paste.
If the clog still seems to be intact, start over at step 1 and repeat the process a couple of times. For extra-stubborn clogs, you can let the fizz mixture sit overnight or combine this method with plunging.
You can clean toilet stains with a toilet brush, baking soda, and white vinegar. Household cleaning ingredients like Borax or a wet pumice stone can also scrub away tough mineral stains. If a light cleaning can't break through stubborn toilet bowl stains, you're probably dealing with mineral stains.
Water entering through the rim of the bowl can also be slowed by mineral deposits in the small holes under the rim. The best toilet bowl cleaner I've come across in these situations is muriatic acid. This is a very powerful chemical that should be used with great care and respect.
A spray consisting of equal parts vinegar, baking soda and water is an excellent multipurpose cleaner. Sprinkle a cup of borax and a quarter-cup of vinegar into your toilet bowl, let it sit overnight, then scrub and flush in the morning.
Add about 1 cup of baking soda to the toilet bowl, then add another 1 to 2 cups of vinegar. You should see and hear some fizzing action—this means that it's working! Let the solution sit and fizz for about ten minutes.
Hydrogen Peroxide and Vinegar
“Combining these two creates peracetic acid or corrosive acid, an irritant that, in high concentrations, can harm the skin, eyes, throat, nose, and lungs,” says Bock.
Like bleach, it effectively kills fungi, spores, and yeast. We recommend using hydrogen peroxide because it is a safer, more environment-friendly alternative to bleach products. It's a biodegradable material made of water and oxygen that completely decomposes.
Cleaning with a mixture of baking soda and vinegar in the bathroom can work really well. To clean your toilet with vinegar, pour a cup of vinegar in the toilet bowl and let sit overnight. The next morning, sprinkle a little baking soda into the bowl, scrub, and then flush clean.
Steel wool scrub
Since steel wool is such an abrasive product, you can either use it alone or in addition to borax + vinegar +/or baking soda for better results. 0000-grade steel wool is recommended as it's less likely to scratch up the inside of a porcelain toilet.
The carbonic acid that is in coke is what helps to clean toilet stains. Picture the acidity slowly working its way through the stains, melting them away. It can take a while depending on how stubborn the stain is which is why it's vital to have a suitable cleaning method depending on how bad the toilet condition is.
