Carpet Cleaning Myths: What Really Works and What Doesn't

Carpets take a beating—spills, foot traffic, pet hair, and everyday dust all work their way deep into the fibres. While there’s plenty of advice out there on how to clean carpets, not all of it is reliable. Some common carpet cleaning myths do more harm than good, leading to damaged fibres, set-in stains, or worse—an even dirtier carpet.

So, what actually works, and what should you stop doing immediately? Let’s separate fact from fiction.

Myth #1: Baking Soda Alone Removes Stains

The Claim: Sprinkling baking soda on a stain will lift it right out of your carpet.

The Truth: While baking soda is great at neutralising odours, it’s not a miracle stain remover. It absorbs moisture, which can help with fresh spills, but it won’t remove tough stains on its own. Worse, if not vacuumed thoroughly, it can build up in carpet fibres and be difficult to extract fully.

What Works Instead: Blot stains immediately with a mixture of warm water and mild detergent. For stubborn stains, a vinegar and water solution followed by gentle blotting can be more effective.

Myth #2: Carpets Only Need Cleaning When They Look Dirty

The Claim: If the carpet looks clean, there’s no need to clean it.

The Truth: Dirt and allergens don’t just sit on the surface; they settle deep within the fibres, even if the carpet appears spotless. By the time dirt is visible, it’s already accumulated to a point where it may cause damage.

What Works Instead: Vacuum at least once a week and schedule deep cleaning every 12 to 18 months to maintain carpet health and air quality.

Myth #3: Steam Cleaning Shrinks Carpets

The Claim: Steam cleaning damages carpets by causing shrinkage.

The Truth: Modern steam cleaning methods, when done professionally, won’t shrink carpets. Shrinkage typically happens when carpets are over-saturated and left damp for too long, which can be caused by poor technique or cheap rental machines.

What Works Instead: Always use professional-grade equipment or hire experienced carpet cleaners who know how to regulate moisture levels. If DIY-ing, ensure proper drying by ventilating the room or using fans.

Myth #4: Vinegar Cleans Everything

The Claim: Vinegar is a universal cleaner that works wonders on carpets.

The Truth: While vinegar is useful for breaking down some stains, it’s acidic and can damage certain carpet fibres, especially wool or delicate synthetic materials. Overuse can also leave behind a strong smell that lingers.

What Works Instead: Use a pH-balanced carpet cleaner designed for your specific carpet type. If using vinegar, dilute it properly and spot-test before applying it to a larger area.

Myth #5: Scrubbing Stains Makes Them Disappear Faster

The Claim: Rubbing a stain vigorously will remove it quickly.

The Truth: Scrubbing only pushes the stain deeper into the fibres, making it more difficult to remove. It also frays the fibres, causing visible damage.

What Works Instead: Blot stains gently with a clean cloth or paper towel, working from the outside in to prevent spreading. Patience is key—let cleaning solutions sit for a few minutes before blotting again.

Myth #6: Carpet Cleaning Causes Mould Growth

The Claim: Cleaning carpets too often leads to mould.

The Truth: Mould growth only occurs when carpets remain damp for extended periods. If carpets are dried properly after cleaning, there’s no risk of mould.

What Works Instead: Proper ventilation, using dehumidifiers, and professional-grade extraction methods ensure carpets dry quickly and safely.

Myth #7: DIY Machines Work Just as Well as Professional Carpet Cleaning

The Claim: Rental carpet cleaning machines do the same job as professional services.

The Truth: While DIY machines can help with surface-level dirt, they often lack the power needed to extract deep-set grime. Many also leave carpets overly wet, increasing the risk of mould and mildew.

What Works Instead: Use DIY machines for occasional maintenance but schedule professional cleaning for deep cleaning to remove embedded dirt, bacteria, and allergens.

What Actually Works: Best Carpet Cleaning Practices

Now that we’ve debunked the myths, here’s what actually helps keep carpets in top condition:

✔ Vacuum regularly – At least once a week or more in high-traffic areas.
✔ Act fast on spills – The quicker you address a stain, the easier it is to remove.
✔ Use the right cleaner – Check the label for carpet-safe formulas.
✔ Deep clean annually – Professional carpet cleaning prolongs the life of your carpet.
✔ Proper drying is key – Ensure carpets dry completely to prevent damage.

The Takeaway: Smart Carpet Care for Long-Lasting Results

Keeping carpets clean isn’t just about appearance—it’s about preserving their quality, maintaining indoor air health, and avoiding costly replacements. By ditching outdated cleaning myths and following proper techniques, you can keep your carpets fresh, stain-free, and looking their best for years.

FAQs

How can I prevent carpet stains in the first place?

Using area rugs, doormats, and a no-shoes policy indoors can help minimise dirt and spills. Regular vacuuming also prevents dust from settling deep into fibres.

Is professional carpet cleaning really necessary?

Yes, especially for high-traffic areas. Professional cleaning removes deep-seated dirt and allergens that standard vacuuming or DIY machines can’t reach.

What’s the safest homemade carpet cleaner?

A mixture of warm water, mild dish soap, and a few drops of essential oil (like lavender or tea tree) works well for general cleaning. Always test a small area first.
