Finding mould on your sofa cover can be unpleasant, especially when you have spent time cleaning your living room and keeping your furniture fresh. Small mould spots, a musty smell or damp patches on the fabric can all be signs that moisture has become trapped in or around your sofa.
In UK homes, this can be particularly frustrating during autumn and winter, when cold weather, condensation and drying laundry indoors can make it harder to keep soft furnishings dry.
The good news is that preventing mould on sofa covers starts with a few simple habits: controlling moisture, improving airflow, cleaning fabric correctly and making sure covers dry completely before use.
If mould has already appeared, the right approach depends on how much fabric is affected, whether the cover is washable and whether the problem has spread into the sofa cushions underneath.
In this guide, we'll explain how to prevent mould on sofa covers, what to do if you discover mould, how to clean different types of covers safely and when cleaning alone may not be enough.
Whether you have a fitted stretch cover, a velvet cover or a removable family sofa cover, these practical tips will help you look after your furniture.
Why Does Mould Grow on Sofa Covers?
Mould is a type of fungus that can grow when moisture and suitable conditions are present. Sofa covers can be affected when they remain damp, when condensation develops around furniture or when liquid becomes trapped between the cover and the upholstery.
Common causes include the following.
1. Damp Covers After Washing
One of the most avoidable causes is putting a cover back onto the sofa before it has dried completely.
The outside of the fabric may feel dry while thick seams, folds or areas around elasticated edges still hold moisture.
When a damp cover is placed over foam cushions, moisture may become trapped between the layers, creating conditions in which mould can develop.
2. Poor Ventilation
Rooms with limited airflow can allow moisture to accumulate.
This is particularly relevant when furniture is placed close to cold external walls or when laundry is dried indoors without adequate ventilation.
If the back of a sofa is pressed tightly against a damp wall, the lack of airflow can make it harder for the area to dry.
3. Spills That Have Not Dried Properly
Drinks, water from wet clothing and other spills can leave moisture in the fabric or underlying cushion material.
Even when the visible mark disappears, moisture may remain beneath the surface.
Cleaning spills promptly and allowing the affected area to dry properly can help
