If you get brown stains in your toilet bowl, the good news is that it's not caused by anything that you, ahem, do in the bathroom. 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.
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.
The contaminants notorious for causing brown stains in toilet bowls are iron, manganese and sulfur. These pollutants can also produce iron bacteria, manganese bacteria and sulfur bacteria, which also can produce brown stains.
Green or brown stains in the toilet usually indicate lime buildup. Lime scale forms as hard water evaporates and leaves a mineral buildup behind.
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.
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.
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.
A few different things can cause the brown build-up at the bottom of your toilet bowl. One possibility is that your water contains a high level of iron, which can leave behind rust-colored stains. Another possibility is that you have hard water, which can also cause mineral deposits to accumulate in your toilet.
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.
To prevent calcium carbonate from piling up into your cistern, pour a single cup of white vinegar into it. The mixture should be three parts white vinegar to one water. After you pour it into the cistern, mix it slowly and carefully until it's evenly distributed.
Brown stains are the result of hard water and not your cleaning wrongly. Don't use bleach as it will only bleach out the stain, but not remove it. Use a clean brush with plastic bristles.
Hard water is water with especially high mineral content, containing mainly magnesium, calcium, bicarbonates, and sulfates. Mineral buildup from dried hard water, also known as limescale, can form chalky white residue and rust-colored stains on toilets, faucets, showers, and sinks.
A frequent cause of smelly drains and dirty toilets are urine sediments. Urine scale occurs as urine particles build up on the porcelain. As hard water evaporates, it leaves behind calcium and magnesium deposits which combine to form limescale.
There are four kinds of toilet bowl stains: hard water, rust, mildew, and mold. If you have mold, you may want to leave it to the experts because of the toxicity. However, you may be able to handle all four types of stains with household remedies.
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.

Cleaning your toilet tank is pretty quick and easy with vinegar and baking soda. You only need to do it once or twice a year, and it can help get rid of bacteria, mold, and mineral deposits to keep you and your family healthy.
Once a week at least. Tetro says your bathroom is the ultimate bacteria host; E. coli can be found within six feet of the toilet and in the sink. To keep it at bay, disinfect the toilet and sink at least once weekly, and the bathtub every two weeks — more if you shower often.
Leaving bleach in a toilet overnight is fine, but you shouldn't leave it any longer, or else it might corrode your toilet. If you do decide to leave it in the bowl overnight, let other members of your household know so that they don't use the toilet and accidentally mix the bleach with ammonia from urine.
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.
