A cleaning influencer's trick using a common household product has proven effective for restoring stained grout. White toothpaste, available at Tesco for just 50p, can make grout appear whiter in as little as five minutes.
The Problem with Grout
Grout is porous, meaning it has tiny holes that easily trap dirt, leading to dark stains and eventually mould and mildew. Many people neglect grout cleaning, but it can ruin the look of a bathroom.
Toothpaste: An Unexpected Solution
Lynsey Crombie, known as the Queen of Clean, recommends white toothpaste for grout cleaning. Its thick consistency and ingredients like baking soda and peroxide help lift stains. Unlike gel toothpaste, white toothpaste lacks artificial colorants that could transfer onto tiles.
How to Clean Grout with Toothpaste
Apply a small amount of white toothpaste to an old toothbrush, rinse it with warm water, and scrub the grout. The mixture foams immediately, and stains begin to fade within a few scrubs. For tougher stains, scrub more persistently in a back-and-forth and circular motion. The bathroom will smell minty fresh.
Results and Recommendations
This hack works well for light stains, but deeper-set stains like mould may require stronger products. The toothpaste method is quick, inexpensive, and surprisingly effective for routine grout maintenance.
