After a long day, you may look forward to curling up on your couch, or in your favorite armchair to relax. But, if your fabric furniture has been exposed to damp conditions for an extended amount of time, something else may be making itself at home—mold. Before you junk a moldy upholstered piece of furniture, know that you may be able to save it. Use these tips to learn how to remove mold from fabric furniture.

Why Does Mold Grow on Fabric?

Mold thrives in damp conditions, so if a piece of fabric furniture is left out in the rain or stored in a humid environment, mold spores can move into the fabric and take up residence. While every mold species has its preferred environment, the fibers of upholstery and the cellulose of wood furniture make inviting homes for various types of mold. 

The air around you is full of mold spores, but mold doesn't usually become a problem until humidity levels reach 60%, which is why keeping your home's humidity level under 60% is ideal. Where you keep your furniture also matters. If you place an easy chair or couch under a leaky pipe in the basement or leave upholstered outdoor furniture out in the rain, mold can take root.  

How to Identify Mold

If your furniture is moldy, you'll most likely be able to see and–potentially–smell it, as mold spores produce a musty odor. Since mold can be an allergen or irritant, don't lean in too close to your furniture to smell it. Instead, keep your distance and note if you detect a musty smell in the air. 

Molds come in a rainbow of colors, from pink to green and black to white. The color of mold indicates the species and often the age of the mold spores. Any type of mold can be bad for your health, so don't worry too much about the specific color. Regardless of the color, mold will usually have a fuzzy appearance, similar to velvet.

If you see a patch of mold on your furniture, you may be able to clean it up yourself. Several types of cleaning products work to remove mold, and will skill any mold spores on fabric. Be sure to always wear gloves, goggles and a safety mask to protect yourself when working around mold. 

Since the sun can help kill mold, try to clean any moldy furniture outside on a sunny day. You will start by vacuuming the area of the furniture that has visible mold to remove the mold spores from the surface.Use a vacuum with a good filter, so the mold doesn't release into the air. 

Vinegar Solution

Vinegar is an excellent mold killer and a relatively affordable and safe option. Combine one part vinegar and one part water in a spray bottle, then spritz over the moldy area. Sponge down the area to remove the mold, and to ensure the vinegar soaks into the fabric. 

Once the mold is gone, spray the area again with clean water to rinse the vinegar away. If you can remove the upholstery from the furniture, do so and toss it in the washing machine to clean it. 

Hydrogen Peroxide

Hydrogen peroxide will also kill mold on fabric. You can either use an oxygenated bleach powder mixed with water, per the instructions on the package, or a 3% hydrogen peroxide solution, which is the concentration you're likely to find on a drugstore shelf. 

Pour the peroxide into a spray bottle and spritz the moldy area with it, or use a washcloth or sponge to dab the peroxide onto the fabric. Let the peroxide soak into the fabric for about one hour, wipe it with a sponge to remove the mold. Rinse with water and dry. 

Similar to the vinegar solution, once you've rinsed away the peroxide, you can try washing any removable cushion covers in your washing machine.

Bleach Solution

Bleach will also kill mold on fabric, but isn't suitable for all fabric types, since it will remove dyes and colors along with the mold. Check the tag on your furniture to confirm that bleach is OK to use before proceeding.

If bleach won't harm your fabric, combine 1/2-cup of bleach with 1 quart of water, then pour the solution into a spray bottle. Spritz on the moldy area and let it soak for 15 minutes. Use a sponge to wipe the area and remove the mold, then rinse the fabric to remove the bleach. 

How to Prevent Mold on Furniture

The best way to prevent mold from growing on your upholstered furniture is to keep your furniture in a dry area with good airflow. The following tips can help:

  • Use a dehumidifier to keep the relative humidity indoors under 60%.

  • Store outdoor furniture under a cover, especially when it rains.

  • Clean up any spills on the furniture right away, being sure to dry the area.

  • If storing your furniture, keep it away from pipes or leaky areas.

DIY vs. Hiring a Pro

You can remove mold from furniture on your own, if the moldy area is small and doesn't cover the entire piece of furniture. If the mold covers a large area, or you suspect that it may be growing throughout your home, hiring a local mold removal company is the way to go. 

A mold removal company will inspect your home, determine the source of the mold, the extent of it, and recommend a treatment plan. For large areas of mold, hiring a professional is much safer and more effective than trying to DIY.

How Much Does it Cost to Remove Mold?

It doesn't cost much to correct a small mold problem, especially if you're able to clean the furniture yourself. You'll only need to buy the cleaning product, which you may have already. 

For a bigger mold remediation project, the cost increases considerably. The average professional mold remediation cost is over $1,100. Don't be scared away by the cost, though. Professional mold removal is often the safest and most effective option, making it worth every penny.

Frequently Asked Questions

Mold can be hazardous to your health. Some people are allergic to mold and experience a reaction when exposed to mold spores. The reaction varies from person-to-person, but can include a runny nose, skin irritation, and asthma attack. Mold can also be irritating to people who aren't allergic, causing respiratory, skin, and eye irritation. In some cases, mold exposure can lead to infections.
