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.
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.
Another popular method to remove limescale from your toilet is to use vinegar and baking soda. 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.

Vinegar is a natural acid that can dissolve calcium deposits. You can pour vinegar into the toilet bowl and let it sit for a few hours before scrubbing with a toilet brush.
What does limescale look like? Limescale can take many shapes and forms, it's often a white deposit when seen on surfaces like a chrome tap or coloured plastic, but inside of a toilet where the ceramic is white – it often just collects over time and then causes unsightly stains.
White crusty deposits that may accumulate around the toilet bowl, the end of a faucet or showerhead or appear as water spots come from water rich in the naturally-found calcium or magnesium minerals often referred to as water hardness.
Use Coke specifically when you need to remove problem stains like limescale or rust. If you want to avoid the risk of tinting your toilet with Coke, a light-colored carbonated soft drink such as 7UP or tonic water will also suffice.
The best way to tackle this problem is with an acidic solution, which can cut through the limescale. This can be achieved by using household products like baking soda and white vinegar.

Always rinse away with cool water after two minutes of contact.
Just as natural dish soap helps break down dirt, grease, and food that may be stuck on dishes and utensils, it can help break down what's in your toilet bowl.
Limescale toilet buildup is a result of hard water flowing through the pipes and leaving behind deposits of magnesium and calcium that gradually build up into stains and scaling. You can spot these stains and scaling almost anywhere the hard water flows: around taps, pipes, and toilet bowls.
Hard water stains are known by many names – limescale, mineral deposits, mineral buildup, hard water deposits – but the meaning is the same. Hard water stains appear as chalky white residue that results from buildup of excess minerals present in hard water.
Hard water buildup in your toilet can be one of the most obvious signs. A white or rust-colored ring forming at the waterline or staining at the base of the bowl may appear. In more extreme cases, limescale and calcium accumulation can plug the water jets under the toilet rim, resulting in slow, weak flushes.
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.
Use Vinegar & Baking Soda
White vinegar is a natural solution that can be utilized to dissolve calcium buildup. Sitting overnight, you will be able to remove lime buildup from the drain while avoiding the harsh chemicals in traditional drain cleaners. Avoid putting any store-bought chemicals down the drain.
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.
