In the following section, we will delve into the nitty gritty of cleaning toilet stains with the help of some good you may have in your pantry.

Vinegar And Baking Soda

Start by pouring a cup of vinegar into the bowl and using a toilet brush to spread it under the rim. Let it sit for a few minutes or a day, giving it time to break down the stains.

Then, sprinkle baking soda around the rim and over the vinegar-soaked areas. Baking soda acts as a gentle abrasive, scrubbing away stains without scratching the porcelain.

The mixture will fizz, helping to lift stains and grime. Scrub thoroughly with the toilet brush, focusing on any persistent stains. Flush the toilet to rinse away the residue.

Citric Acid

Our findings show that citric acid is the active ingredient in lemons that helps effectively remove hard water stains and buildup under the toilet rim.

Simply juice one to two lemons and mix the juice with hot water in a 1:2 ratio. This solution can be sprayed down or saturated with a cloth on the affected area. The acidity in the lemon juice acts to dissolve the mineral deposits, facilitating easier removal.

After the soaking period, use a toilet brush to scrub under the rim, making sure to reach all areas. Flush the toilet to rinse away the loosened deposits and lemon juice solution.

What Is the Brown Gunk Under the Toilet Rim?

Our research indicates that the brown gunk is primarily mineral deposits, mold, mildew, and bacterial growth.

This unsightly buildup is a common issue in bathrooms and can be attributed to hard water, which contains high levels of minerals such as calcium and magnesium. These minerals can crystallize and form stains when water evaporates.

Additionally, the dark, moist environment under the toilet rim provides an ideal breeding ground for mould and bacteria. Regular cleaning can help maintain a clean and hygienic toilet.
