5 Effective Steps to Clean a Polyester Couch

A polyester couch is one of the most popular choices for homes in Australia because it looks good, feels comfortable, and lasts longer than many other fabrics. Polyester is tough and resistant to wear, but like any fabric, it collects dust, stains, and odours over time. In fact, your sofa can harbour 75 times (7500%) more bacteria than your toilet seat.

If you don’t take care of it regularly, small marks and odours can accumulate, making your sofa appear older than it really is. The good news is that cleaning polyester doesn’t have to be complicated or expensive. With the right routine, you can keep it fresh, soft, and stain-free for years.

In this home sofa cleaning guide, we will show you 5 effective steps to clean a polyester couch. Each step solves a specific problem you face—from everyday dust to deep stains and odours.

Why Should You Clean Your Polyester Couch?

• To Prevent Dust and Allergen Build-up: Sofas trap dust, pollen, and pet dander. Around 20% of Australians at certain periods of their life suffer from allergic rhinitis triggered by dust mites and allergens. Dirty upholstery can also irritate sensitive skin. Regular cleaning reduces these irritants.
• To Prevent Bacteria and Germs: A neglected sofa can harbour bacteria from food spills and dirty hands. Research shows that upholstered furniture can contain more bacteria than a toilet seat if not cleaned regularly.
• To Mitigate Mould and Mildew Risk: Polyester resists moisture better than cotton, but liquid stains left untreated may still lead to mould. Indoor mould exposure is linked to respiratory issues and asthma flare-ups. Cleaning your sofa prevents mould exposure. 
• To Control Odour: Sweat, spills, and pet accidents can cause sofas to smell. Bad odours are often caused by volatile organic compounds (VOCs) from bacteria, which can irritate your eyes, nose, and throat.
• For Air Quality Improvement: A dusty sofa circulates particles into the air every time you sit. Poor indoor air quality is linked to respiratory diseases, cancer, and heart disease. 
• To Get a Longer Lifespan of Furniture: Cleaning prevents fibre damage from dirt and oils. Without maintenance, dirt acts like sandpaper, wearing down fabric faster.

5 Steps to Clean a Polyester Couch

Let’s go through 5 efficient steps for DIY couch cleaning, removing bacteria, dust, and debris to keep it clean, refreshed and healthy.

Step 1: Vacuuming Your Fabric Sofa

Your first step is to remove the dirt, dust, and hair that loosely sit on the surface of your couch. Dust and crumbs not only make the sofa look dirty, but they can also wear down the fibres over time. 

Vacuuming fabric sofa surfaces regularly will prevent dirt from penetrating deeper into the fabric. 

Here’s what you should do:

• Remove Loose Items: Take off all cushions, throw pillows, blankets, and loose objects from the sofa.
• Use a vacuum cleaner with a soft upholstery brush or attachment.
• Pay extra attention to seams, corners, and under cushions, where dirt tends to settle.
• Do this twice a month if the couch is used daily.

This step might feel simple, but it’s the foundation of polyester fabric cleaning. If you skip it, spill stains (if they happen) will sit on top of dust particles, making them harder to remove.

Think of vacuuming as your preventive care. A clean base makes every other cleaning method more effective.

Step 2: Spot Treatment for Couch Stain Removal

At your home, spills are unavoidable. Coffee, sauces, or even pet accidents can quickly leave marks on your sofa. 

So, what you need to do is to act fast with couch spot treatment before stains set into the fibres.

Here’s how you can handle different stains:

#1 Removing Liquid Stains (coffee, juice, and other liquids): 

• Blot immediately with a clean, dry cloth. Avoid rubbing—it spreads the stain. 
• Mix a few drops of mild dish soap with about 1 cup of warm water.
• Stir until it’s slightly foamy.
• Dip a clean microfiber cloth into the soapy water.
• Wring it out so it’s damp, not dripping.
• Gently dab or blot the stained area with the cloth.
• Work from the outside of the stain toward the centre to stop it spreading.
• Dampen another clean cloth with plain water (no soap).
• Blot the same area to remove any soap residue.
• Use a dry towel to press the spot.
• Let the couch air dry completely.

#2 Removing Grease Stains (food, oil): 

• Sprinkle baking soda on the spot. 
• Let it sit for 15 minutes, then vacuum it away. Next, use a mild soap solution.
• Then follow the previous soapy solution, same as the liquid stains. 

#3 Removing Pet Stains From Couch: 

• Mix equal parts white vinegar and water
• Spray lightly on the area, and blot with a microfibre cloth. This neutralises odours too.

You can remove the couch stains if you treat them fast, such as within 10 to 20 minutes. Waiting longer allows stains to penetrate and bond with fibres, making them tougher to clean.

DIY eco-friendly stain remover solutions, such as using vinegar, baking soda, and water, are safe cleaning solutions for polyester and won’t damage your upholstery.

Step 3: Deep Cleaning Polyester Upholstery

Even with regular vacuuming and spot cleaning, polyester couches eventually need a more thorough cleaning. Oils from skin, sweat, and long-term spills sink deep into the fabric. 

That’s when deep cleaning polyester upholstery becomes necessary. For a deep cleaning, you should use a steam cleaning method for your polyester sofa. 

For tougher stains, steam cleaning polyester couch fabric is a good option. Steam penetrates deeper than surface scrubbing and loosens embedded dirt. 

1. Preparation & Safety Check

• Check the Care Tag: Locate the tag (usually underneath cushions) and identify the cleaning code.
  • W or WS: Steam cleaning is generally safe.
  • S: Solvent-based cleaning only—do NOT steam clean.
  • X: Vacuum only—do NOT steam clean.

2. Steam Cleaning Steps

• Use the Right Attachment: Attach the upholstery tool to your steam cleaner.
• Apply Steam: Hold the nozzle a few inches away from the fabric (or follow your machine’s instructions) and move the cleaner slowly and steadily across the surface.
• Extract: Use the extraction/suction feature of the steam cleaner to lift and remove the loosened dirt and moisture immediately.
• Systematic Cleaning: Clean the entire frame of the sofa first (working top to bottom on vertical surfaces) and then move on to all sides of the cushions. Avoid oversaturating the fabric.
• Tough Stains: Go over any stubborn stains a couple of extra times, making sure to extract the moisture immediately.

Note: Work on one section of the sofa at a time (e.g., an arm, a back section, or a single cushion side).

Step 4: Couch Odour Removal

A clean couch can still smell musty if you don’t tackle odours. Polyester fabric can trap smells from food, pets, and sweat.

Here’s how to refresh your sofa:

• Baking soda: Sprinkle baking soda evenly over cushions and leave for a few hours before vacuuming. This neutralises common odours.
• Vinegar mist: Mix equal parts water and white vinegar in a spray bottle. Lightly mist the sofa, but don’t soak it. Since vinegar evaporates because of having 4.5% to 12% acetic acid, it takes odours with it.
• Fabric refresh spray: Use eco-friendly sprays designed for upholstery to add a pleasant scent.

If odours persist after these steps, professional deodorising may be necessary. This is often the case for couches exposed to smoking or heavy pet use.

Step 5: Ongoing Couch Maintenance for Long-Term Cleanliness

The final step involves establishing habits that keep your sofa looking and smelling good throughout the year. A proper couch maintenance routine prevents stains and odours from becoming constant problems.

Here’s a simple routine you can follow:

• Weekly: Vacuum the couch and fluff the cushions.
• Monthly: Wipe down with a damp microfiber cloth for a refreshing touch on your fabric couch.
• Quarterly: Wash removable covers (check care tags first).
• Yearly: Schedule a professional clean for a full refresh.

To improve stain resistance, consider applying a fabric protector spray containing silicone or fluoropolymer. These create a protective layer that makes liquids bead up instead of soaking in, which supports stain prevention for sofas.
