Citric acid
More importantly, it's probably even more effective than vinegar for getting rid of that brown stain in the toilet. Simply pour a kettle of almost boiling water into the bowl, follow up with 250ml of citric acid, and leave it for some hours – preferably overnight. The next day, scrub and flush.
That brown toilet-bowl stain isn't what you think it is
It's actually due to high concentrations of minerals in hard water, like calcium, iron, and manganese, that build up inside the toilet bowl over time, according to Hunker. In particular, iron oxide, or rust, is the main problem.
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.
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.
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.
In this case, a basic toilet cleaning product may not be enough, and you will need to use undiluted bleach. As a one-stop cleaning solution, pour one cup of bleach around the bowl. Then tackle every inch with a toilet brush or a handheld scrub brush. Let it sit for five minutes, then flush.
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.
The main disadvantage is the small disinfecting and oxidising ability of hydrogen peroxide at active concentrations (tens of milligrams per litre), which are required for swimming pool disinfection. Another problem is the quick decomposition of hydrogen peroxide in water and the presence of oxygen radicals.
The disinfecting power of HOCl surpasses the effectiveness of traditional bleach by at least 80 times. Dwell Time: Bleach disinfectants must be left to dry on a surface for 5 to 10 minutes to actively kill germs.
For the health of patients within a hospital or any healthcare building, hydrogen peroxide should be the main choice for use in cleaning.
OxiClean contains several ingredients, but the important one for boosting and brightening laundry is sodium percarbonate — basically, dry hydrogen peroxide plus washing soda (also called sodium carbonate, which is very similar to but not exactly baking soda).
However much you are making, just add twice as much hydrogen peroxide as you do the detergent. So for a small stain mix 1 teaspoon of Dawn with two teaspoons of peroxide. For a large batch 1 cup of hydrogen peroxide to ½ cup detergent works!
Hydrogen peroxide also kills normal cells within the wound — including healthy skin cells and immune cells — and slows blood vessel formation, all of which are important for wound healing. It's a similar story with rubbing alcohol, another substance commonly thought to help sanitize a wound.
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.
Due to environmental concerns, the product has been discontinued; by 2013 its last original US trademark was cancelled or allowed to expire.
Grab some gloves and use a Magic Eraser to go to town on toilet bowl stains. Some users even recommend cutting a piece off and letting it dissolve the bowl to remove that unsightly ring all on its own.
Pour about one cup of white vinegar into the toilet bowl, followed by about one cup of baking soda, then let it rest for around 10 minutes. It's a good idea to wear gloves when using this as a toilet cleaner and to have eye protection.
One of the most obvious signs of hard water buildup is in the toilet. You might see a white or rust-colored ring forming at the waterline or staining at the base of the bowl.
