How to Clean Your Toilet Tank

Typically, cleaning a toilet involves a quick wipe of the bowl, followed by a flush, and that's it. Toilets that see daily use are easier to maintain because the frequent flushing helps keep the water and air moving, preventing the buildup of unwanted substances. And by substances, we mean things like mold and bacteria. However, if you have a seldom-used toilet, or you've been away for a week or two, you might open the lid to find a mold ring around the bowl from stagnant water. And if it’s in your bowl, it’s probably in your tank as well.

Cleaning the interior of your toilet tank might not be part of your regular cleaning schedule, but it’s wise to do so occasionally to reduce germs and keep the tank’s internal mechanisms running smoothly. Plus, minerals found in tap water, such as lime and calcium, can accumulate over time and interfere with the tank's function. Regularly descaling your tank is a good preventative measure.

Cleaning the inside of your toilet tank is a straightforward task, particularly if there isn’t much buildup. Simply remove the lid, pour in your chosen cleaning solution, and scrub the sides with a sponge or toilet brush, ensuring you don't dislodge any tubes or chains. Flush a few times to ensure the cleaning solution is completely rinsed out. Keep reading for additional tips on how to clean the inside of your toilet tank.

Cleaning Tips for the Toilet Tank Interior

To thoroughly clean your toilet tank, it's essential to use the right cleaning products. Vinegar is an excellent solution for this task—it's chemical-free, naturally antibacterial, and acidic, which helps dissolve minor lime and calcium deposits. Just pour a couple of cups into the tank, let it sit for about an hour, then scrub and flush to rinse. However, if you prefer the strong scent of chemicals, bleach is a powerful disinfectant that will eliminate mold. Keep in mind that bleach won't help with calcium deposits, so you’ll need a cleaner with acid that’s safe for porcelain surfaces.

For stubborn, caked-on stains, you'll need to get inside the tank. If you're not keen on immersing your hands in the water, you can drain the tank by turning off the water supply, usually located at the lower back of the toilet, and flushing before you begin scrubbing. Cleaners tend to work more effectively when they're not diluted in water—this is true for the bowl as well. Just remember that chemical cleaners can damage the rubber flapper, which could lead to leaks. While you're at it, check the condition of the flapper to ensure it's still functioning properly.
