How to Clean Upholstered Furniture
Fabric sofas and chairs are some of the hardest-working surfaces in a Toronto home — and among the least cleaned. Upholstery absorbs skin oils, food particles, pet dander, and dust over time, leading to embedded stains, dullness, and odour. Here's how to clean it properly without professional equipment.
Step 1 — Check the Care Tag
Every upholstered piece has a care tag with a cleaning code:
- W — Water-based cleaners only
- S — Solvent-based (dry-clean only) cleaners only — no water
- W-S — Either water or solvent cleaners
- X — Vacuum only — no liquid cleaners of any kind
Using the wrong cleaner can permanently damage fabric or cause shrinkage. If the tag is missing, test any cleaner in an inconspicuous area first.
Step 2 — Vacuum Thoroughly
Use an upholstery attachment on your vacuum. Remove cushions and vacuum both sides, the cushion covers, and the frame underneath. Get into the crevices where crumbs, pet hair, and dust collect. This step alone makes a significant difference.
Step 3 — Spot Treat Stains
For W-coded fabrics: mix 1 tablespoon of dish soap with 2 cups of cold water. Apply with a clean white cloth — blot, never rub. Work from the outside of the stain inward. Rinse by blotting with a cloth dampened with plain cold water. Blot dry.
For S-coded fabrics: use a dry-cleaning solvent from a hardware store. Apply sparingly to a cloth and blot — never apply directly to the fabric.
Step 4 — Full Surface Clean (W or W-S fabrics)
Mix 1/4 cup of dish soap with 1 cup of warm water and whip it into a foam with a hand mixer or whisk. Apply only the foam (not the liquid) to the fabric with a soft brush in circular motions. The foam lifts dirt without saturating the fabric, which prevents watermarks. Wipe with a clean damp cloth and let air dry completely — use a fan to speed drying and prevent mildew smell.
Step 5 — Deodorize
Sprinkle baking soda liberally over the entire surface. Let sit for 15–20 minutes (or longer for stronger odours). Vacuum completely. This neutralizes absorbed smells from cooking, pets, and daily use.
Specific Fabrics
- Microfibre: Usually W or W-S coded. The foam method works well. Brush lightly with a soft-bristle brush after drying to restore the texture.
- Velvet: Brush with a soft-bristle brush to maintain the pile direction. Spot clean only — full wet cleaning can crush velvet permanently.
- Linen: W-coded but can watermark easily — use as little liquid as possible and dry quickly.
- Leather: Entirely different process — wipe with a damp cloth and condition with leather conditioner. Never use dish soap on leather.
How Often to Clean
- Vacuum: Weekly or every two weeks
- Spot treat stains: Immediately when they happen
- Full clean: Every 3–6 months
- Professional deep clean: Annually for heavily used pieces
