How to remove a mildew smell in foam cushions
Keep mildew smells at bay with common household chemicals. (Jupiterimages/ Images)

If any of the foam cushions in your home have had prolonged exposure to moisture, the inner fibres may contain mould and mildew. Mould and mildow not only pose a health threat, but they produce an unpleasant odour. Because cushions are generally too big for a washing machine, you have to seek other methods for deodorisation. Fortunately, you can use a couple of common household chemicals -- baking soda and vinegar -- to get rid of mould, mildew and their residual odours.

Skill level:

Things you need

  • Baking soda

  1. 1

    Place your foam cushions in a well-ventilated area, preferably outdoors on a sunny day. Let them sit in the open air for 24 hours to air out.

  2. 2

    Sprinkle generous amounts of baking soda onto the cushions. Baking soda is widely used as a deodoriser and works well on mildew smells. Let the baking soda soak up the odour overnight.

  3. 3

    Shake out the bulk of the baking soda. Beat the cushions vigorously to remove any deep-seated baking soda. Use a vacuum cleaner to suck up any excess powder.

  4. 4

    Pour vinegar into a spray bottle and lightly spritz the cushions all over. Don't be alarmed if the cushions start to fizz and produce foam; this results from the vinegar reacting with trace amounts of baking soda. Vinegar will not only help deodorise the cushions, but it is also a strong disinfectant and will kill any mildew or mould. Allow the cushions to air dry completely before bringing them back inside. The vinegar smell should dissipate within a couple of hours.
