Green or brown stains in the toilet usually indicate lime buildup.
Coke works incredibly well. Use a plastic cup to remove water in the bowl and pour a big bottle of coke in. Let sit for a few hours and use the toilet brush to scrub. Will look like new.
The most common deposit on toilets is calcium carbonate (referred to as limescale), from water that has passed through chalk or limestone rocks. It's usually light brown/beige in colour. If it's stained with iron from water that goes through iron bearing rock,it will be darker.
Red-brown rust stains result from the presence of iron in water, making itself at home in your toilet bowl, tub, and sinks. Air combines with the particles, causing them to oxidize and color. Over time, they build up on surfaces where water drips.
Iron bacteria can also cause reddish, yellow, brown, or gray deposits or orange or opaque slimy strands inside toilet tanks or orange-colored water.
Iron Bacteria produce a sticky slime which is typically rusty in color, but may be yellow, brown, or grey. This slime sticks to well pipes, water treatment equipment, and plumbing fixtures. Standing water such as a toilet tank is a common place to find this “slime”.
Brown, besides the usual clear, is typically the most common color observed in discolored toilet water. There are numerous causes, but the most common include: Rusted Pipes – Old, corroded pipes can cause water discoloration as rust particles break off and flow with the water.
Brown stains in a toilet bowl are often caused by rust, which can be due to iron in the water, hard water deposits or old pipes. The stains can also be caused by calcium or mineral deposits.
Pour undiluted white vinegar into your toilet bowl, making sure you get it up under the rim where limescale often gathers and cover every part of the surface. Leave it for three to four hours and then scrub it with a brush. Repeat if necessary.
Allowing days or weeks to pass without thoroughly cleaning your toilet bowl can cause mold, bacteria, and brown deposits to form inside the bowl and tank. When these deposits mix with the incoming clean water during flushing, they give the water a brownish tint.
Use vinegar or another acidic cleaner to clean calcium buildup from your toilet. The acid will break down the mineral deposits so you can brush them away. Be sure to take the necessary safety precautions when working with cleaners. Wear gloves and eyewear and open windows for ventilation.
If you see pooling water around your toilet's base, clean up the water and thoroughly scrub the tiles until they are clean and dry. Wait a few minutes before reevaluating the space for leakage. If the pooling water returns after you clean the area, you probably have an under-tile toilet leak.
Although this nuisance means more scrubbing the toilet bowl (more on the best pro cleaning tricks below), there's a chance it's also a clue you should get your blood sugar checked. As strange as it sounds, frequently seeing mold in your toilet could be one of the first signs of diabetes.
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.
It can, and you get a similar effect if you use other acidic foods and drinks, like lemon juice. But these are not very good choices for cleaning. Coca‑Cola contains phosphoric acid, a safe food ingredient used in some of our beverages which can help clean off dirt.
Limescale is a white, chalky substance that builds up and collects on appliances and surfaces because of calcium and carbonate ions found in hard water. It contains minerals that are regularly found in hard and unfiltered water, and the stains can leave your house looking dirty and unkept even if it's not.
Hard water stains can be pretty common in your toilet bowl. And while your first thought might be to treat them with Clorox® Disinfecting Bleach to remove the stains, we don't recommend it in this case.
Who knew that dishwasher tablets could help keep your toilet sparkling clean? Just drop a dishwasher tablet in toilet bowl and let it sit for 10-15 minutes. Then, use a toilet brush to scrub the bowl and flush it. The tablet will help to break down any stains or buildup in the bowl, leaving it fresh and clean.
White vinegar
The mild acid can dissolve limescale and disinfect. All you need to do is pour a generous amount of white vinegar down your toilet bowl, let it soak in overnight, then scrub with a brush. Then flush to rinse, and voilà, your toilet is back to its former whiteness!
One of the most common causes of brown water in your toilets is rust in the pipes. Over time, galvanized iron pipes can corrode, releasing rust particles into the water supply.
Hard water is water that contains high levels of minerals such as calcium, magnesium, and iron. As the water evaporates, the mineral deposits can stick to the inside of the toilet bowl or reservoir. Over time, these deposits can grow, harden, and develop into rust-like stains.
