We are sometimes asked “will my mattress get mouldy in self storage?”
Humidity is one of the main causes of mould for mattresses.
When you look for a storage facility, you want to consider how that facility looks after their units. Self storage containers should be vented to help prevent mould.
It’s important to keep your unit free from condensation, so that you don’t cause it to become humid by adding moisture. This means not storing items with water in them – so, contents such as washing machines need to be thoroughly drained before storing. Fridges should be defrosted and thoroughly dry.
Another reason mattresses can become mouldy is if they are not clean when they are stored away. Before storing a mattress, it is sensible to use a vacuum cleaner on it, followed by an upholstery cleaner or baking powder to absorb any odours. Leave it outside to dry in the air (when it’s not raining, obviously!) and make sure it is completely dry before bringing it in. Once you are sure that it is completely dry, you can cover the mattress to protect it and keep it clean. If you are going to cover it in plastic, it’s even more important to ensure that there is absolutely no moisture still remaining in the mattress. Otherwise, the plastic will trap any humidity inside and make it more likely to become mouldy.
