How to Deal With Mildew on Your Furniture

Mildew shows up as a faint gray or white patch on wood, fabric, or cushions. It smells musty and can make you uncomfortable. If you see it, act fast – the longer it stays, the harder it gets to clean.

Most mildew appears in damp places: near windows, in basements, or behind sofas that sit against a wall. Poor airflow and high humidity give it the perfect breeding ground. Even a small spill that stays wet for a day can trigger growth.

Simple Steps to Prevent Mildew

First, keep humidity below 60 %. A cheap hygrometer will tell you the level, and a dehumidifier can pull excess moisture out of the air. Open windows when the weather is dry, and let fresh air circulate around large pieces.

Second, wipe down spills right away. A damp cloth is fine, but avoid leaving any water on the surface. For sofas, pull the cushions aside and let the interior dry fully before putting them back.

Third, use protective covers on outdoor or garden furniture. A breathable cover stops rain from soaking the wood while still letting air move.

Cleaning Mildew Off Furniture

If you already have a spot, start with the gentlest method. Mix equal parts white vinegar and water in a spray bottle. Spray the affected area, let it sit for 10 minutes, then wipe with a clean cloth. Vinegar kills most mildew spores without harsh chemicals.

For stubborn patches, sprinkle baking soda on a damp sponge and scrubbing gently. Rinse with a light mist of water and dry completely. If the furniture is fabric, use a steam cleaner on a low setting – the heat kills the spores and the steam lifts the stain.When dealing with wood, avoid soaking it. Dampen a cloth with a solution of one part bleach to ten parts water, rub the spot lightly, and wipe dry immediately. Test the mixture on an inconspicuous area first to make sure the finish isn’t damaged.

After cleaning, let the piece dry in a well‑ventilated room. A fan or open window speeds up the process. Once dry, sprinkle a light coat of talc or cornstarch on fabric to absorb any remaining moisture.

If the mildew has penetrated deep into cushions or upholstery, consider professional upholstery cleaning. They have industrial extractors that pull out spores and restore the material.

Finally, keep an eye on the problem. Check hidden spots every few weeks, especially during rainy seasons. Early detection saves you time and money.

By controlling humidity, cleaning quickly, and using simple home solutions, you can stop mildew from ruining your furniture. A fresh, dry home means a healthier space for you and your family.
