Moldy Furniture? Spot It, Clean It, Stop It

Got a couch that smells musty or a wooden table with dark spots? That’s a sign of mold. It’s more than an eyesore – it can damage your furniture and affect your health. The good news is you don’t need a professional right away. With a few tools and the right steps, you can handle most cases yourself.

How to Spot Mold on Your Furniture

First, look for the tell‑tale signs. Mold shows up as fuzzy patches in black, green, or white. It loves damp corners, so check under cushions, behind sofas, and inside drawer bottoms. A sour or earthy smell is another clue – you might not see the growth, but the odor tells you it’s there.

Don’t forget hidden places. Upholstery seams, the underside of chairs, and the back of shelves can hide mold where it’s easy to miss. If you’re unsure, run a white cloth over the surface; a change in color or a damp feel means you’ve found it.

Cleaning and Protecting Moldy Pieces

Once you know where the mold is, grab a few supplies: a spray bottle, white vinegar or hydrogen peroxide, a soft brush, and a clean rag. Mix equal parts water and vinegar, spray the affected area, and let it sit for ten minutes. The acidity kills most mold spores without harming wood or fabric.

For tougher spots, use 3% hydrogen peroxide. Spray, wait a few minutes, then scrub gently with the brush. Avoid harsh chemicals like bleach on upholstery – they can discolor the fabric and release fumes.

After scrubbing, wipe the area with a damp cloth to remove any residue. Let the piece dry completely; good airflow speeds up the process. If you can, place a fan nearby or move the furniture to a sunny spot.

Once clean, protect the surface. A light coat of furniture sealant or a fabric protector spray creates a barrier that makes future mold growth harder. Re‑apply every few months, especially after cleaning or moving the piece.

If the mold has soaked deep into cushions or inside a wooden frame, it might be time to replace the padding or consider professional restoration. Persistent smell after cleaning is a red flag – don’t ignore it.

Preventing mold is easier than fighting it. Keep humidity below 60% with a dehumidifier, especially in basements or rooms with little ventilation. Wipe up spills immediately and avoid leaving furniture in damp basements or garages for long periods.

Use breathable covers on sofas and chairs; plastic wraps trap moisture and invite mold. Rotate cushions regularly so the same spot doesn’t stay compressed and damp.

In short, spotting mold early, cleaning with vinegar or peroxide, drying thoroughly, and adding a protective layer keeps your furniture looking good and safe. Next time you notice a musty scent, you’ll know exactly what to do.
