How to Deep Clean Carpets and Upholstery (DIY vs. Professional)
No matter how much you vacuum them, carpets and sofas will quietly collect dust, dirt, and other types of bacteria that sit deep within the fibres. Over time, this hidden build-up will affect how your space looks, feels, and potentially even smells. It can also affect the air quality within your home or workplace.
This highlights the importance of deep cleaning, not just for aesthetic purposes, but also for maintaining health. Deep cleaning will help to remove trapped allergens, refresh fabrics, and extend the lifespan of your carpets and upholstery.Â
Experts recommend deep cleaning every six to twelve months, depending on the amount of foot traffic in your space and whether pets or children are regularly present.
In this blog, we will share our recommended tips for deep cleaning your carpets and upholstery properly. We will look at the differences between DIY cleaning and professional cleaning services, helping you decide which approach is best for your needs.
The Science of Carpet and Upholstery Dirt
Carpets and upholstery collect so much more than you can see. Every time someone walks, sits, or moves around, tiny particles are pressed deep into the fabric. Dust mites, pet hair, pollen, body oils, and even bacteria can slowly build up on them over time. While regular vacuuming may remove some, a significant amount of this dirt remains hidden beneath the surface.
The fibres in carpets and soft furnishings are absorbent and slightly textured, which is what helps dirt cling to them so easily. Regular deep cleaning will help penetrate the surface and lift out trapped grime, leaving your fabrics fresher, brighter, and healthier.
Ever wondered what could be hiding in your carpet and sofa?
- Dust mites and allergens
- Pet hair and dander
- Body oils and residue
- Bacteria and odour-causing germs
- Pollutants brought in from the outside
DIY Deep Cleaning: Step-by-Step
Deep cleaning carpets and upholstery yourself can deliver great results if done properly and carefully. We recommend following these simple steps to refresh your fabrics and remove any dirt that has accumulated over time.
- Vacuum thoroughly: Go over each area twice in different directions each time, as this will help remove as much surface dust as possible.
- Spot treat stains: Use a professional cleaning product specifically designed for your fabric type and gently blot the area, avoiding scrubbing.
- Use a carpet shampoo or steam cleaning machine: Follow the manufacturer’s guidelines and instructions, working slowly to achieve an even clean.
- Let everything dry completely: If any moisture is left behind, it can cause mould and lingering odours.
- Keep up with regular maintenance: Vacuum weekly, move furniture and clean under it occasionally, and use fabric protectors where possible.
Tip: Always test any cleaning solution on a small, hidden area first to check for colourfastness.
When DIY cleaning works best:
- Light dirt
- Smaller spaces
- Frequent cleaning
- On easy-to-care-for materials
Professional Deep Cleaning: What to Expect
A professional deep clean will deliver results that regular DIY methods simply cannot match. Skilled technicians will use powerful cleaning machinery and fabric-safe cleaning solutions to remove deep-set dirt, stains, and allergens from carpets and upholstery.
Here’s what you can expect from a professional service:
- Pre-inspection: Before commencing any cleaning, the technician will inspect your fabrics to identify any stains or areas that require special attention.
- Pre-treatment: A targeted cleaning solution will be applied to loosen any dirt and oils.
- Deep cleaning: Methods like hot water extraction, dry compound cleaning, or encapsulation are used to ensure a thorough clean.
- Rinse and extraction: The remaining residue and moisture are lifted out to leave the fabrics fresh and clean.
- Final grooming and drying: Fibres will be brushed and left to dry evenly to ensure a smooth finish.
When professional cleaning works best:
- Large spaces
- Heavy stains
- Delicate fabrics
- Allergy-prone environments

Frequently Asked Questions (FAQs)
How do you clean a deeply dirty carpet?
To clean a deeply dirty carpet, start by vacuuming thoroughly to remove loose debris. Then, treat stains with a carpet-safe pre-treatment spray. Use a hot water extraction (steam cleaning) machine with a specialised carpet detergent to penetrate deep into fibres and lift embedded dirt. For optimal results, we recommend working in small sections and allowing the carpet to dry completely before use.
Tip: For heavily soiled areas, repeat the process or consider a professional carpet cleaning service for optimal results.
What do professionals use to clean carpets?
Professional carpet cleaners typically use hot water extraction machines (commonly called steam cleaners) combined with high-powered suction and specialised detergents. These machines inject hot water and cleaning solution deep into the carpet fibres, then extract it along with dirt, allergens, and residues.
They may also use pre-sprays, agitation tools, and deodorisers for stain removal, odour control, and deep fibre cleansing.
How to make carpet look new again?
To make your carpet look new again, you need to:
- Vacuum thoroughly to lift dirt and restore pile height.
- Use a carpet shampoo or a steam cleaner to thoroughly clean the carpet.
- Treat spots and stains with targeted removers.
- Rake or brush the carpet fibres post-cleaning to fluff them up.
- Finish with a carpet deodoriser for a fresh scent.
Regular maintenance and deep cleaning every 6–12 months will help to preserve the colour, texture, and softness of your carpet.
Is it better to shampoo or steam clean carpets?
Steam cleaning is generally more effective than shampooing for deep carpet cleaning. It uses hot water extraction to penetrate deeply into the fibres and remove embedded dirt, allergens, and bacteria. Shampooing can leave behind residue, which may attract more dirt over time.
Choose steam cleaning for a more thorough, hygienic clean, especially in high-traffic or pet-prone areas.
