1
Turn off the water supply and drain your toilet tank. Reach down behind your toilet and find the metal valve on the wall that connects to the water line. Turn the valve clockwise until you can’t turn it anymore to shut the water off to your toilet temporarily. Then, flush your toilet and hold the flapper down until all the water drains out.^{[3]

- It’s okay if there’s a little bit of water on the bottom of the tank that won’t drain.
2
Combine baking soda, vinegar, and dish soap in a spray bottle. Mix 1 cup (240 mL) of vinegar with 1/2 cup (64 g) of baking soda in your spray bottle. Then, add 2 tablespoons (30 mL) of dish soap and swish the bottle around to combine everything thoroughly.^{[4]
X
Research source}
- Dish soap helps break down tough stains and mildewed spots, but baking soda and vinegar are also an effective cleaner on their own.
- To combat toilet odors, try adding 10 drops of your favorite essential oil. Tea tree oil and citrus oil are great for covering up bad smells in your bathroom.
3
Spray the solution in the tank and let it sit for 1 hour. Coat all of the surfaces inside of your toilet tank with the vinegar and baking soda solution. Leave the mixture in your toilet tank so it has time to break down all the stains, mold, and mildew from the tank.^{[5]
X
Research source}
- Make sure no one tries to use the toilet while you’re cleaning the tank since it won’t flush properly.
- While the solution sits inside your toilet tank, use the extra time to clean the rest of your bathroom.
- You may also sprinkle dry baking soda into the tank and scrub the surfaces before adding spray. The abrasive baking soda will help remove any marks on the surface.
4
Scrub the inside of the tank with a sponge. Use a slightly abrasive sponge or a scrub brush to clean off any marks and loose residue on the tank walls. For added cleaning power, spray some more of the vinegar and baking soda solution onto the brush while you work. Keep scrubbing until you can’t lift up any more marks.^{[6]

Research source}
- Put on rubber gloves so your skin doesn't get irritated by the vinegar solution.
Reach down behind the toilet and turn the valve counterclockwise to pop the water back on. Then, flush the toilet to rinse out the tank and remove any leftover product.^{[7]

1
Turn off your toilet’s water supply and drain the tank. Locate the metal valve on the wall behind your toilet that controls the water supply. Twist the valve handle clockwise as far as it will go to prevent the tank from refilling. Then, just flush your toilet and let the water drain out.
- There may be about 1 inch (2.5 cm) of water that doesn’t drain out of your tank, but it won’t affect how well you’re able to clean the toilet.
2
Refill the tank with distilled white vinegar. Pour the vinegar in, and make sure it covers the overflow valve, which is a tall vertical tube near the side or middle of your tank. You may need more than one bottle of vinegar because toilet tanks can hold up to 3 gallons (11 L).^{[8]
X
Research source}
- If you want a more effective soak, then use cleaning vinegar, which is more acidic than vinegar you’d use in your kitchen.
3
Let the vinegar soak for 12 hours or overnight. The acidity in the vinegar will break down any tough stains, making it easier for you to clean. You won’t be able to use your toilet while it’s soaking, so let it soak while you’re sleeping or away from home.^{[9]
X
Research source}
- If you’re worried about other people in your household using the toilet, put up a sign to let them know you’re cleaning the tank.
4
Scrub the inside of the tank with a sponge or brush. If there are noticeable marks or stains on the inside of your toilet tank, use a sponge or small brush to scrub them. Keep scouring inside of the tank until you don’t see any more residue.^{[10]

- Put on rubber gloves if you reach inside the tank because vinegar could irritate your skin.
Reach down behind your toilet and turn the valve counterclockwise to get the water back on. Give your toilet a flush to remove the vinegar and rinse out the tank.

Research source}
- Citric acid powder may cause slight skin irritation, so wear rubber gloves when handling it.
Fill a spray bottle with water and use it to spritz the baking soda and citric acid a little at a time. Stir the mixture thoroughly to help it combine with water. Add in a few drops of essential oils, like tea tree oil, lavender oil, or peppermint oil to give it a fresh scent. Keep adding water until the mixture has the consistency of damp sand.^{[12]

Transfer the mixture to a muffin tin and let it dry overnight. Scoop the mixture into the wells on the muffin tin and press it in tightly. Once they’re full, set the mold on your counter overnight so the mixture can dry into tablets.^{[13]

Research source}
- If you don’t have a muffin tin, an empty ice tray will also work great for forming the molds.
4
Drop a tablet in your tank every 1 or 2 weeks to keep it clean. When it’s time to clean your tank, simply take one of the tablets and let it go inside of the tank. The tablet will fizz and slowly dissolve so it disinfects and cleans the inside of your tank.^{[14]
