Is shower mold causing my child's persistent cough?« Back to Previous Page

We've lived in our Jumeirah villa for 2 years and just noticed black spots forming in the grout between the tiles near the shower. My youngest has had a bit of a cough that won't go away, and I'm really worried the mold might be causing it, especially with the humidity lately. What's the safest and most effective way to clean this to make sure it's gone for good and safe for the kids?

It is possible that shower mold is contributing to your child's persistent cough. Mold releases spores and microscopic particles that are respiratory irritants, which can worsen allergies and cause coughing, especially in children whose airways are more sensitive. The high humidity in Dubai creates an ideal environment for mold growth in bathrooms, where it thrives on the constant moisture from showers and condensation.

For the black spots on your grout, start by cleaning with a solution of white vinegar or a dedicated mold-removing cleaner. Scrub the area thoroughly and ensure it is completely dry afterward; using an exhaust fan during and for 30 minutes after showers is critical. For persistent mold growth behind the grout, the issue may be moisture within the wall itself, which surface cleaning cannot resolve.

If the cough persists after cleaning, or if you see the mold returning quickly, a professional inspection is recommended. They can identify if there's a hidden moisture source and perform air or surface sampling to determine the specific type of mold present, which is important for understanding the potential health impact. In many Dubai villas, poor ventilation and constant AC use can create hidden condensation problems that require more than a DIY approach.
