If you smell an odour in the bathroom that will not go away after proper cleaning, odds are you have a mould problem. A mould smell from the bathroom sink drain is a musty odour that permeates the entire room.
Causes of Mold
Mold only needs moisture and an enclosed space. Besides water, other substances like hair, soap and toothpaste run down your bathroom sink drain, sticking to the sides of the drain and creating a haven for mould.
How It Affects Your Health
Mold in bathrooms can cause health problems for people who suffer from asthma or have poor immune systems. Common ailments associated with constant exposure to mould include headaches, sinus problems, eye irritation, skin irritation and cough, reports the New York State Department of Health.
Cleaning Up Mold
You can remove mould from the bathroom sink drain with a mildew remover that does not contain ammonia. Ensure the room receives proper ventilation as ammonia emits a strong odour. If the room does not have a window, use the exhaust fan. It's a good idea to pour boiling hot water down the drain periodically to help clear build-up and decrease the growth of mould.
