How to Refresh a Sofa: Upholstery Cleaning Basics

A sofa takes more abuse than almost anything in the house — daily sitting, spills, dust, and in Calgary, a constant film of fine prairie dust that settles into the weave. Most couches that look "done" aren't worn out; they're just dirty. A proper refresh can pull years of grime out of the fabric and bring the colour back. Here's how to do it right, starting with the one step everyone skips.

Read the tag first

Flip up the cushions and find the manufacturer's cleaning code, usually on a tag under a seat cushion. It tells you what the fabric can actually handle:

• W — water-based cleaner is safe.
• S — solvent only; water will stain or shrink it.
• WS — either water or solvent is fine.
• X — vacuum only at home, no liquid at all; leave any deeper cleaning to a professional.

Using water on an S-coded fabric is the fastest way to leave a ring you can't get out. If there's no tag, test any cleaner on a hidden patch first — the back corner or under the skirt.

The weekly-to-monthly refresh

Most of what dulls a sofa is dry soil, and you can remove a surprising amount with no liquid at all.

1. Vacuum thoroughly. Use the upholstery attachment and get into the seams, under the cushions, and along the back. Crumbs and grit act like sandpaper on the fibres every time someone sits down.
2. Brush the fabric. A soft-bristle brush lifts matted pile and pulls embedded dust to the surface so the vacuum can grab it.
3. Deodorize. Sprinkle baking soda lightly over the whole surface, leave it 15–20 minutes, then vacuum. It pulls out the everyday smell that builds up over a long Calgary winter of closed windows and furnace heat.

Spot-treating stains in a dry Calgary home

Move fast and blot — never rub, which drives the stain deeper and frays the fibres.

• Fresh spills: blot with a clean white cloth from the outside of the spill inward.
• W or WS fabric: mix a few drops of dish soap in warm water, dampen a cloth (don't soak it), and blot. Follow with a clean damp cloth to lift the soap, then let it air dry.
• Grease or ink (S fabric): a small amount of dry-cleaning solvent on a cloth, dabbed gently.

Less liquid is always better. Over-wetting upholstery pushes moisture into the foam and frame, where it dries slowly and can turn musty — a real risk even in Calgary's dry climate, where you'd never expect a damp-smell problem.

Don't forget the cushions, arms and headrests

The places people touch most hold the most grime, and they're easy to miss:

• Arms and headrests collect skin oils and hair product that turn the fabric dark and slightly shiny. On W or WS fabric, go over them with the same mild soap solution, working in small sections and blotting dry as you go.
• Cushion covers often have zippers, but that doesn't mean they're meant to go in the washing machine. Many shrink or fade unevenly, and a cover that no longer fits never looks right again. Check the tag, and clean them on the cushion unless it says otherwise.
• Flip and rotate cushions every couple of weeks so they wear and fade evenly. The seat everyone favours flattens first.
• Check underneath. Coins, pens and snacks under the cushions can leave marks, and a pen left in a seam is a common source of ink stains.

Protect it between cleanings

A few habits stretch the time between deep cleans:

• Keep it out of strong sunlight or draw the blinds on bright afternoons. Calgary gets plenty of clear, sunny days year-round, and direct sun fades fabric and weakens fibres, especially on south- and west-facing windows.
• Use a throw where pets or kids sit most, and wash it regularly.
• Deal with spills the same day. Almost any stain is easier to lift fresh.
• Watch for dye transfer. New dark jeans and damp outdoor clothing can bleed colour onto light fabric.

Frequently Asked Questions

What do the cleaning codes on my sofa tag mean?

W means water-based cleaners are safe, S means solvent only, WS means either is fine, and X means vacuum only with no liquid at all. The tag is usually under a seat cushion. If there's no tag, test any cleaner on a hidden spot first.

Can I use baking soda to deodorize my couch?

Yes. Sprinkle a light layer over the fabric, leave it for 15–20 minutes, then vacuum it up thoroughly. It's a simple way to lift the stale smell that builds up over a long Calgary winter with the windows closed.

How often should I clean my sofa?

Vacuum and brush it weekly to monthly, depending on how much use it gets, and spot-treat spills right away. A professional deep clean every year or two helps pull out the soil that home methods can't reach, especially in homes with pets or kids.

Can I clean a sofa with a rental carpet machine?

It's risky. Rental machines tend to over-wet upholstery, pushing moisture into the foam and frame where it dries slowly and can turn musty. Professional extraction rinses the soil out and pulls the water back so the fabric dries quickly.

When to bring in a pro

DIY handles surface dirt and small spills well. Call a professional when:

• The fabric is coded S or X, or has no tag and you're not sure.
• The whole sofa looks dull and flat — that's deep soil that home methods only smear around.
• There's a set-in stain, pet odour soaked into the cushions, or any sign of mould.
• It's a high-value or delicate piece (velvet, silk blends, antique frames).

Professional upholstery cleaning uses hot-water extraction or low-moisture methods matched to your fabric, with equipment that rinses the soil out and pulls the water back so it dries fast — not the soak-and-hope you get with a rental machine. For Calgary homes, that fast dry-back matters: it prevents the trapped moisture that turns a refresh into a musty smell.
