What's the best local product to kill bathroom mold?« Back to Previous Page

We’ve lived here for 2 years and just noticed these black spots spreading in the corner where the shower is in our Marina apartment. It’s been so humid lately that the walls never seem to fully dry out, even with the AC on. What’s the most effective product I can find locally to kill this mold and stop it from coming back?

Based on your description of persistent high humidity in your Marina apartment, you are dealing with a classic case of condensation-induced mold growth, which is extremely common in Dubai's climate. The constant use of AC can sometimes create cold surfaces that attract moisture, exacerbating the problem in poorly ventilated areas like shower corners.

For a small, localized area, a product containing chlorine bleach can be effective for non-porous surfaces like tiles and grout. Look for a thick, gel-based mold remover, such as HG Mould Spray or a similar product available at ACE Hardware or Waitrose, which will cling to vertical surfaces. However, these are only superficial solutions. The key is not just to kill the visible mold but to address the underlying moisture issue. Without improving ventilation and reducing humidity, the mold will return.

It is critical to note that if the black spots are widespread, have penetrated porous materials like drywall or the ceiling, or if you have any concerns about potential health effects, a professional inspection is strongly advised. DIY attempts on larger infestations can disturb spores and spread them throughout your apartment.

For a permanent solution that addresses the root cause, I recommend contacting our specialists at Saniservice.
