There is always moisture in the air, even when you cannot see it. When the air gets colder, it cannot hold all the moisture and tiny drops of water appear, particularly on cold surfaces. This is condensation. You may notice it on your windows, particularly in the morning or as the mist on the mirror when you have a bath. Condensation mainly occurs during cold weather. It tends to appear on cold surfaces and in places where there is little movement of air. Condensation can lead to mould.
Mould will appear as small black and green spots. Mould is a living organism so needs killing to get rid of it. To do this, wipe down affected areas with a fungicidal wash, remember to wear rubber gloves and follow the manufacturer’s guidelines.
The only lasting way to avoid severe mould growth is to eliminate dampness ie condensation.
