One cleaning expert has warned that the use of white vinegar could be doing more harm than good, particularly to certain types of shower heads. While it’s true that the acid in white vinegar can help dissolve limescale, prolonged exposure may cause permanent damage to materials such as chrome and brass.
Even more worryingly, white vinegar should be completely avoided on nickel finishes, which are highly susceptible to corrosion. For those using white vinegar, the expert says it should never be left on for more than 30 minutes, and even then, with caution.
Thankfully, there’s a safer and equally effective alternative for tackling limescale without risking damage to your fixtures.
Instead of white vinegar, cleaning expert Jess Thomas, managing director of Drainage Central, recommends using lemon juice.
Lemon juice can be mixed with a few tablespoons of baking soda to form a powerful paste that’s gentle on shower finishes but tough on grime.
Using an old toothbrush, scrub the paste directly into the shower head and then rinse with warm water for sparkling results. This method avoids the risks associated with vinegar while still achieving a thorough, chemical-free clean.
Why does lemon work?
Jess explained that lemon juice contains natural citric acid that can help to dissolve mineral build-up.
She adds: “As a general guide, you should aim to clean your shower head at least once a month to remove any limescale or bacteria. Untreated limescale can cause water blockages as well as lower the water pressure of the shower head.
“If you live in an area with hard water, you may need to clean your shower head more often, as this can cause limescale to develop faster because of the water’s high mineral content.
“Cleaning regularly helps maintain strong water flow and ensures your shower remains hygienic.”
For those looking to cut down on how often they need to clean, Jess suggests dismantling the shower head for a deeper clean.
She advises removing the shower head (if possible), taking it apart, and soaking each component in warm water and either lemon juice or white vinegar, depending on the material.
“Rinse the shower head with warm water and it can then be reassembled as normal,” she said.
For more stubborn limescale, specialist limescale removers are available, but gloves should always be worn.
