Many areas within the home are frequently overlooked during regular cleaning, allowing mould, bacteria, dust, and grime to accumulate. Dr Primrose Freestone, an associate professor in clinical microbiology at the University of Leicester, has highlighted several such hotspots.
The area behind and around the toilet, often missed during cleaning, can harbour black, slimy mould, skin cells, and airborne bacteria, particularly in poorly ventilated bathrooms. Dr Freestone advises cleaning this spot weekly, at the same time as the toilet bowl, suggesting bleach-based sprays for effectiveness against mould and fungal spores.
Kitchen sinks and drains, as busy food preparation areas, should be cleaned and disinfected daily. Food debris washed down the plughole can feed bacteria, increasing the risk of food contamination. Similarly, frequently touched items like keyboards, remote controls, and mobile phones accumulate oils, sweat, skin cells, and bacteria. Dr Freestone recommends cleaning these devices most days, noting the presence of microscopic fungi on keyboards.
Cleaning inside the fridge at least once a week is also recommended to prevent bacteria build-up and the spread of mycotoxins from old or out-of-date products. Additionally, the warm, damp conditions of a washing machine's rubber seal create an ideal environment for mould and bacteria.
