Hard water contains high amounts of dissolved minerals, including calcium and magnesium. As water flows through your pipes, some calcium and magnesium minerals are left behind. Over time, those minerals can build up, causing unsightly stains and scaling.
The best way to prevent hard water stains and limescale in your toilet is to keep your water soft. Hard water is the culprit for these issues, and water softeners/filtration systems are the solutions for long-term cleanliness of your home and appliances.
Urine stains and limescale in toilets: How deposits form
Urine scale is a mineral compound created by chemical processes: The calcium in the toilet water reacts with substances in the urine. A high pH value means that urine scale is as hard as mineral stone.
Vinegar and baking soda: This natural and inexpensive solution can help dissolve calcium buildup. Start by pouring a cup of baking soda into the drain, followed by a cup of vinegar. Let the mixture sit for a few hours, then flush it out with hot water.
Pure natron is another tried-and-tested solution for removing scale – and not just for toilets. However, natron works most effectively in combination with vinegar. Pour one or two cups of vinegar into the toilet bowl and then sprinkle a few tablespoons of natron on top.
The acidic values of vinegar allow it to soften limescale and prepare it for scrubbing clean. 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.
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.
Heat 1 to 1 ½ cups of white vinegar to about the same temperature you'd take your coffee – not scalding, but warm enough. Add it to the overflow tube and give it about 30 minutes to work. Flush, then go to work on the jet holes, chipping away the scale with something small but solid.
Letting pee sit makes it harder to clean your toilet. This is the best reason I can find for flushing every time you pee. Why? Because the combination of urine and hard water (i.e., water that contains a lot of minerals), if left to sit for a few hours, can create a crusty deposit on the side of the bowl over time.
Cloudy or milky urine may be caused by a high concentration of certain minerals—like calcium or phosphate—in your urine. Cloudy urine can also signal a high level of protein in your urine that may be caused by issues with your kidneys.
Using this method regularly can help keep your toilet clean and hygienic. Additionally, you should use bleach or other cleaning products for tougher stains or odors. However, it's important not to leave the vinegar in the toilet overnight as it can damage the porcelain and reduce its lifespan.
These growths are known as biofilms or 'microbial slime' and are most noticeable in bathrooms and kitchens. If not dealt with at their onset some biofilms can grow into certain materials and become a permanent feature. What are biofilms? Biofilms contain bacteria and fungi that have grown and multiplied on a surface.
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.
The fizzing reaction and gas created may help loosen some small blockages. However, it is not typically strong enough to break down larger clogs or remove hard-to-reach debris. As a result of the above facts, if you have a serious drain clog, using baking soda and vinegar is unlikely to be effective.
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.
Let the CLR sit for 2 minutes.
So, which one should you go for? It really depends on what kind of cleaning you need to do. If you're dealing with really tough, built-up mineral deposits, especially in your bathroom or kitchen, CLR might be the way to go. It's strong enough to handle stains that vinegar might struggle with.
A mild, natural acid, such as lemon juice or vinegar, can be very effective at nipping calcium deposits in the bud. Depending on the severity of the stain, the liquid might have to be reapplied and scrubbed vigorously several times with sandpaper or a rag.
Pour lemon juice or vinegar on the deposits. Don't dilute the vinegar or lemon juice, or you'll reduce its effectiveness. Leave the acidic liquids in place for a few hours to do their work, preferably overnight. Scrub the scale with a stiff-bristled toilet brush before flushing the toilet.
Yes, the acidity of coca cola helps too. Pour coca cola and let it sit overnight. Flush the toilet and scrub if needed.
When it comes to being good for the environment, CLR has a slight advantage. It's biodegradable and part of the EPA's Safer Choice Program, which recognizes products with safer ingredients. Lime Away works well, but it doesn't have the same environmental certifications.
