"The biggest don't when it comes to toilet tanks is bleach—do not use bleach or products containing bleach inside the tank, as it can corrode the internal parts of your toilet. If you are aiming to remove tough stains from the tank, I also recommend white vinegar diluted with water."
What I recommend, that works well is distilled white vinegar. As far as your toilet to keep it clean inside the bowl. Use 1 cup of white distilled vinegar and poor inside your toilet tank, also pour half of that cup in to the overflow, which is the small, round pipe that stands up in the middle of the tank .
Simply measure out half a cup's worth of bleach and pour it into your toilet bowl, using your toilet brush to scrub it into the bowl and beneath the bowl's rim, also allowing five minutes to pass before you flush it all away.
If you can do it safely, scrub the inside of the cistern with a stiff brush and a solution of 1 cup (about 0.25 liter) of unscented liquid household bleach (5%–9% sodium hypochlorite) mixed with 10 gallons (about 38 liters) of water. Rinse the cistern with clean water; then drain.
Vinegar is a great toilet cleaning solution. Not only is it free of chemicals and naturally antibacterial, it's also an acid, so it will remove minor lime and calcium deposits. All you need to do is pour a couple cups of vinegar in your tank and let it sit for an hour or so, then scrub and flush to rinse.
Over time your toilet water can cause an unsightly rainbow of stains and mineral build up in your toilet bowl. CLR Calcium, Lime & Rust Remover helps you flush the filth away. Before you get started, always use gloves and check if CLR is suitable to be applied on the material you are trying to clean.
Pour bleach into them
Bleach is a powerful, toxic substance that should be used carefully and properly, and pouring it down a drain is not a proper use. Bleach can react with other substances in your pipes, potentially release fumes, and further plug up the system.
Don't flush the toilet right away. Instead, let the bleachy water in the bowl stand for 6 minutes; set a timer if you need to.
Baking soda and vinegar, when mixed together, can form a chemical reaction that looks sort of like an eruption. This chemical reaction can help clear your toilet and any pipe clogs that you might have.
You should clean the toilet tank twice per year. If you are using water from a well in an area with hard water, clean the tank quarterly to keep the flush valves in good working order. If your bathroom is in a warmer environment that gets muggy or humid and gets mold often, clean the tank once a month.
If there is a slimy layer around water inside of your toilet tank it is likely caused by iron bacteria. Additional discoloration of the water isn't necessarily caused by the bacteria alone, but very likely because of excess Manganese or iron in your water supply.
You can use straight or a diluted vinegar cleaning solution for the bathroom to clean bacteria, especially around the toilet. 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.
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.
Hydrogen peroxide is a safe bleach alternative that cleans, whitens, and sanitizes, and it's perfect for getting rid of mold, hard water, and other toilet stains. The one-two punch of hydrogen peroxide cleans stains and kills germs, leaving your toilet bright, white, and healthy.
Clean and disinfect your toilet bowl with 1/2 cup chlorine bleach. Pour it into the bowl, and let it stand for ten minutes. Then scrub with the toilet brush and flush.
Bleach is a disinfectant, but that doesn't make it a cleaner. In fact, by using bleach as your bathroom cleaner, you could be causing long-term damage—as well as leaving behind mold, dirt, and other unsavory coatings on your bathroom surfaces.
The corrosive properties of the bleach can wear away at the internal parts of your toilet, such as rubber seals, and cause leaks or other potentially permanent damage.
Here is why bleach can break down clogs…
It releases oxygen molecules that breaks up chemical bonds in the cleaning process. Similar to the cleaning process, bleach can also break chemical bonds specially if the toilet is blocked due to toilet paper or organic materials like hair.

So instead of purchasing those expensive fizzies or abrasive toilet bowl cleaners, head to the fridge and let the carbonation of Coke work its magic on filthy rings, lime buildup, and water stains. Because Coca-Cola contains carbonic, citric, and phosphoric acids, it's great for tough stains and dissolving rust.
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. What's good for those caked-on pots and pans after cooking dinner is also good for removing a brown stain on the bottom of the toilet bowl.
