Polyester blends well with other fabrics, it’s non-allergenic, and purchasing one won’t break the bank. But what is the best way how to clean a couch Polyester?
We know a thing or two about professional upholstery cleaning here at Paul’s Cleaning (Melbourne) Company, so we put together this handy guide to help you.

What is polyester material?

Otherwise known as polyethylene terephthalate, this material is synthetic, which means humans make it. This is different from natural materials like cotton or hemp. 

As we’ve mentioned, polyester is not expensive and is stronger than other fibers. This is a winning combination when it comes to sofas, which are known to take a beating. 

Due to the durability, there are a few ways you can keep it looking fantastic. We recommend reading the entire guide before starting, so you go into the job knowledgeable. 

How to clean a couch with a toolset

  • A vacuum.
  • White vinegar.
  • Baking soda.
  • Warm water.
  • A bucket.
  • A few towels.
  • A scrub brush or two.
  • Time.
  • Patience.

Vacuum polyester couches

The first thing to do when cleaning any couch is to use a vacuum. All kinds of objects get lost in the cushions, like crackers, crumbs, nuts, and the like. 

  • Before you turn on the vacuum, be sure there aren’t any loose coins or valuables lying around. Besides food, it’s easy to lose earrings and other items like that, too. 
  • Once you’ve picked up all the things you don’t want to go into the vacuum, start sucking. 
  • Let that thing get into every nook and cranny you can fit it into. Don’t be shy. 
  • Crumbs and dirt are wonderfully talented at hiding, so give it a once over, and then vacuum your couch again. 
  • Be sure to hit each pillow and cushion on all sides.
  • Vacuum the arms, top, and behind the sofa. These are areas that go unnoticed. 
  • Additional cleaning if you have pets, especially hairy ones like many types of Huskies. Animal hair can accumulate quickly, which is why it’s a good idea to stay on top of it. The more animals you have, the more often you should vacuum. 

Baking powder & polyester

Sprinkle some baking powder all over your sofa. If you like, there are scented kinds in the cleaning aisle of the store. The idea is to get some of the odors off your couch. 

Just think about how much sweat and bodily fluids are expelled on that sofa. If you have a few people in your family, odds are someone slept there and drooled. 

We all leave odors behind. It’s nothing to be ashamed of. Baking soda is a fantastic way to get rid of those less-than-appealing scents. 

All you do is sprinkle it lightly on every area that you can. 

Let it sit for at least ten minutes, but if you can let it sit overnight, even better. The longer it sits, the more odor it will absorb. 

We realize letting it sit all night is difficult, but it will be fresher if you do. Baking soda neutralizes odors by contributing both acidic and basic moleculesOnce you’ve waited the appropriate amount of time, vacuum all the baking soda off your sofa and cushions. Be sure to get it all. 

Spot clean your couch

Now, you want to give your couch a good look over. Do you know where all the spots are? 

Odds are you know about some, and others will come as a surprise. This is the point in your couch cleaning where you try to get rid of them all. This can be done with ingredients you can find in your home or a store-bought spot remover. The choice is up to you. 

If you take a quart of warm water, a teaspoon of white vinegar, and a teaspoon of mild laundry detergent, you can create a spot remover that will work as well as a store-bought cleaner. 

When cleaning spots, you should use a towel that is the same color as your sofa or that color. You don’t want to leave white specks on a dark couch or vice versa. 

  • Dab a small area to start. 
  • Make sure your mixture is working. 
  • Keep dabbing with the towel as much as you can. 
  • Don’t wipe it in long strokes. 

For more prominent stains, work from the inside out. Keep at it. This is where patience comes in. Not all stains are equal. Some can be removed easily, while others take time. 

If you can’t get it all the first time around, keep trying. Polyester is made to resist stains, so your spot removal shouldn’t be too difficult. 

Dry couch cushions

Once you’ve finished with your spot cleaning, you want to get those wet spots dry as soon as possible. There are several ways you can speed up the process. 

  • One way is to let the sofa cushions rest in the sun until they dry. You can get a dry towel and start dabbing to pick up any wetness. 
  • Or you can accelerate the process with a hairdryer. 

The critical thing to remember is that you don’t want to leave your sofa soaking wet. 

  • Get as much water out as you can. 
  • Wet fabrics can become infested with mold, which can be quite an issue. 
  • Mold can be pretty bothersome to those who are allergic. Sufferers can experience a runny nose, red eyes, rash, and sneezing. Mold can even be linked to shortness of breath

As you can see, mold is an issue that you want to prevent. Getting rid of mold is very difficult, and it can ruin your couch. 

So do yourself a favor and dry those wet spots as best as you can to avoid any problems. It would be a shame if your cleaning venture ended up with you needing to replace your sofa due to mold.  

Brush your couch

Now that your sofa is dry, get a scrub brush that’s clean and dry. Using a small, circular motion, start to revitalize the material on your couch. While polyester is durable, you just put those fibers through a bit of a workout. By brushing them out, your threads will jump up again and come to life, comments cleaning expert Martina Simons.

Pay special attention to the areas where you did the spot cleaning. Wetness can cause materials to flatten. This is another reason why using a clean scrub brush is a great way to get those polyester strands to stand out. 

Steam clean your couch

Sometimes stains and spots are stubborn, and a steam cleaner can get places that you can’t. How? 

These beautiful machines allow for purified steam and detergent to permeate the materials and get deep down in the fabric to suck them suck back in, according to experts at Complete home filtration. Steam is the result of boiling water, which is why you need a machine like this. There are a ton of other benefits that steam cleaning your home can bring. 

  • First, it’s eco-friendly because the primary source is H2O. 
  • Second, steam cleaners kill viruses, mold, and other germs that could be hiding inside the fibers of your cushions. 

Allergens are no match for the hot steam either, and steam cleaners are lovely at eliminating odors. 

The thing you need to know is that using a steam cleaner is safe, but you need to know what you’re doing. If you have questions about cleaning, don’t hesitate to give us a call. 

How to deal with polyester emergencies

We all have accidents. Sometimes it’s a glass of red wine, and other, it’s a bit of that chocolate you were eating. Sofas take all kinds of abuse because we spend so much of our time relaxing on them. 

When you or someone in your house spills on your sofa, the best way to treat it is right away. You shouldn’t wait until it’s time to clean a couch before getting rid of those stains. It’s always best to take care of spills as soon as you can. 

Some things, like red wine, can leave significant stains that are nearly impossible to remove. Blot that mess as much as you can. Then pour baking soda on it and let it sit for a few minutes. The baking soda will absorb the liquid. Use a vacuum to pick up the baking soda and then repeat. 

Do this until all the wetness is absorbed. Then, use the spot cleaning mixture we gave you above and start dabbing. If the cushion is too wet, use the baking soda to pull it out. Keep repeating these steps until you can’t see the red wine anymore. 

Is polyester better?

When it comes to a couch, there are tons of choices for materials. Sofas come in leather, cotton, linen, acetate, wool, hemp, silk, polypropylene, acrylic, nylon, and rayon. Those are a ton of choices, and they all have beautiful attributes. 

The nice thing about polyester is that it can be woven with other fibers. While it can’t be mixed with leather, cotton and wool are great options. When polyester is blended with natural fibers, you end up with a material that is breathable and durable. The best of both worlds.

But it’s essential to keep on top of any spills and regularly clean your sofa, and know how to benefit more from professional upholstery cleaning

Frequently asked quesions for

How to clean a 100% polyester sofa?
Cleaning a polyester sofa is relatively straightforward due to the fabric’s durability and stain resistance. Start by vacuuming the entire surface with an upholstery attachment to remove loose dirt, crumbs, and dust from crevices and seams. Check the care label—most polyester sofas are labelled with a “W” (water-based cleaning) or “SW” (solvent or water-based). For routine cleaning, mix a few drops of mild dishwashing liquid with warm water until it creates light suds. Dip a soft cloth or sponge into the solution, wring it out well so it’s damp rather than wet, and gently wipe down the fabric in circular motions. For spot cleaning, work from the outside of the stain towards the centre to avoid spreading. After cleaning, use a clean, damp cloth to remove any soap residue, then blot with a dry towel. Allow the sofa to air dry completely, opening windows or using fans to speed up the process. Regular vacuuming between deep cleans will help maintain your polyester sofa’s appearance and extend its lifespan.
Can I steam clean a polyester couch?
Yes, steam cleaning is generally safe and highly effective for polyester couches, as the synthetic fibres can withstand moderate heat without damage. Steam cleaning offers excellent sanitisation benefits, killing dust mites, bacteria, and allergens whilst lifting embedded dirt. However, always check your sofa’s care label first—if it displays an “S” code (solvent-only cleaning), steam cleaning isn’t recommended. Before proceeding, test the steam cleaner on a hidden area, such as the back or underside, to ensure the fabric doesn’t react poorly. When steam cleaning, hold the nozzle slightly away from the fabric rather than pressing directly against it, and work in sections using overlapping passes. Avoid oversaturating any area, as excessive moisture can lead to mildew or water marks. After steaming, ensure the room is well-ventilated and allow several hours for complete drying—you can use fans or a dehumidifier to accelerate this. Steam cleaning every 6-12 months, combined with regular vacuuming, will keep your polyester sofa looking fresh.
Can you use vinegar on a polyester couch?
Yes, white vinegar can be safely used on polyester couches and works particularly well for removing odours and tackling certain types of stains. Create a cleaning solution by mixing equal parts white vinegar and warm water in a spray bottle. The vinegar’s acidity helps break down dirt and neutralise smells without damaging synthetic fibres. Lightly spray the solution onto stained or odorous areas—don’t saturate the fabric—and gently blot with a clean microfibre cloth. For stubborn marks, let the solution sit for 5-10 minutes before blotting. The vinegar smell will dissipate as it dries, taking unwanted odours with it. After treating with vinegar solution, go over the area with a cloth dampened in plain water to remove any residue, then blot dry with a towel. Whilst vinegar is safe for polyester, always spot-test in an inconspicuous area first, particularly on coloured or patterned fabrics. Avoid using undiluted vinegar, as the concentrated acid could potentially affect fabric dyes or finishes over time.
Can you use a Little Green machine on a polyester couch?
Yes, a Little Green machine (or similar portable carpet and upholstery cleaner) works excellently on polyester couches and is specifically designed for this purpose. These machines combine cleaning solution with suction to deep-clean upholstery whilst extracting dirt and excess moisture effectively. Before using it, vacuum your sofa thoroughly to remove surface debris. Fill the machine with the recommended cleaning solution—either the manufacturer’s formula or a mixture suitable for upholstery (check your sofa’s care label for compatibility). Work in small sections, making slow, overlapping passes without lingering too long in one spot, which could oversaturate the fabric. The machine’s suction will remove most of the moisture immediately, but some dampness will remain. After cleaning, allow the sofa to dry completely in a well-ventilated space—this typically takes 2-6 hours depending on humidity and airflow.
