The bathroom can be a Mecca for mould, with the damp, humid conditions providing the perfect environment for spores to grow. While there are plenty of specific mould and mildew cleaning products out there, for people veering towards eco-friendly cleaning solutions there are options.
Cleaning influencer and professional organiser Neat Caroline regularly shares housework tips and tricks with her audience of 209.2K followers on TikTok. She shared her “favourite natural ingredient” to tackle mould which may have built up in your shower cubicle or on grout “for good”.
In a video, she explained: “Today I am sharing how to clean your mouldy shower using one of my favourite natural ingredients. Hydrogen peroxide.”
Although manufactured hydrogen peroxide can be purchased, it is a naturally occurring ingredient and one which experts say is “eco-friendly”.
Scientists from Barnhardtcotton explained: “Hydrogen peroxide is definitely eco-friendly. This compound is basically water with an oxygen molecule, expressed in chemical nomenclature as H202.

“It’s naturally occurring, formed by sunlight acting on water, and hydrogen peroxide is produced by both plant and animal cells. Thus, hydrogen is of the environment and for the environment.”
Hydrogen peroxide is commonly used to disinfect open wounds since it has antimicrobial properties. However, research by the CDC has found hydrogen peroxide has the potential to kill bacteria, viruses, fungi, and mould spores.
Caroline explained: “You’re going to grab three percent hydrogen peroxide and spray it along the mouldy areas. Let that sit for 10 minutes.”
At this point, Caroline recommends leaving your shower door open to dry out. She continued: “10 minutes later you’re going to grab a scrub brush and just scrub away any mould.”

Caroline explained: “As another trick, you can have some equal parts water and vinegar on hand. Just spray down those surfaces that are prone to getting mouldy and this will keep that mould in check.”
She added: “In case it wasn’t clear, don’t mix hydrogen peroxide and vinegar as this can be toxic.” Vinegar has anti-fungal and antibacterial properties, and it can be a cheap and effective treatment for many types of mould. This is thanks to the high percentage of acetic acid in vinegar, which is usually between five and eight percent.
Experts from Healthline explained: “Research has found that vinegar is effective at preventing mould growth on fruit and at removing some common household moulds, but it isn’t effective at killing every type of mould.”
A 2015 study published in the International Journal of Environmental Research and Public Health, found that vinegar made out of four to 4.2 percent vinegar acetic acid was effective at treating Penicillium chrysogenum but not Aspergillus fumigatus. Both are common household moulds.
