Finding the best carpet cleaner for mold is crucial when moisture problems lead to musty odors, dark patches and potential health concerns in your home. Mold can grow deep within carpet fibers and padding, making it difficult to remove with standard carpet shampoos or surface cleaners. Without proper treatment, it can continue to spread and return.
The right carpet cleaner for mold targets spores at the source, lifts contamination and helps prevent regrowth.
We compare the best carpet cleaners for mold based on cleaning effectiveness, safety, ease of use and overall value to help you restore a cleaner, healthier living space.
Top Picks







BISSELL Oxy Deep Clean Carpet Solution
You get a powerful, oxygen-boosted formula that lifts deep grime and most household stains very effectively. It also contains a protectant to help guard against future soiling, making it a strong all-round choice for homes with pets or heavy footfall.
What this solution is for
If you’re asking which is the best carpet cleaner for mold, this formula stands out for attacking deep, set in dirt and stubborn contaminants at the source. Its oxygenated action helps lift embedded stains and residues from both carpets and upholstery, while the included protector helps reduce re soiling after cleaning. That makes it a strong option when you need more than a quick surface clean especially on mold, mildew, and other deeply embedded issues.
Key features and benefits
Practical insights and use cases
You’ll see best results on stairs, high traffic living areas and homes with pets. Users report dark brown extracted water after a first pass on heavily soiled carpets, showing how much grime it dislodges. For stubborn marks allow the solution to dwell briefly and agitate pile with the machine or a brush to help the foam penetrate.
Limitations and tips
The product performs very well but you should be realistic: it doesn’t remove every mark instantly mechanical agitation and repeat passes help. Use warm water in your machine where safe, test a discreet area first, and allow thorough drying between passes. If you’re price-sensitive, use the measured dose rates to get the best value.
Pro-Kleen Pro+ Concentrated Carpet Shampoo 5L
You get a strong, concentrated detergent that stretches a long way — ideal for large homes or multiple cleans. It’s formulated to lift dirt, revive pile and neutralise pet odours without being overly expensive per litre.
Who this is aimed at
Choose this concentrate if you clean large areas regularly, have pets, or want better value per clean. The 5-litre format is intended for owners of carpet machines who will do multiple cleans.
Key features and performance
Practical experience and benefits
You’ll find it restores pile and colour where carpets have become flattened and dull. Owners report dramatic before and after changes on old, sun faded or heavily soiled carpets. Because a small amount dilutes into many litres of working solution, the running cost is low compared with single-use bottles.
Limitations and usage advice
Dilute accurately to avoid over-foaming or residues — follow the manufacturer’s instructions for your machine. If you’re lifting very heavy staining you may still need a targeted pre-spray, but for most pet-related odours and general grime the concentrate performs strongly.
Vax Original Everyday Carpet Cleaner Solution
You get a gentle but effective cleaner suited to routine carpet and upholstery care, with a pleasant Rose Burst scent. It’s Wool Safe approved, so it’s a sensible choice for delicate fibres and frequent use.
Purpose and primary uses
This is a straightforward everyday carpet cleaner aimed at keeping carpets and upholstery fresh between deep cleans. It’s formulated to remove common spills and surface dirt while leaving a pleasant scent.
Key features
What you can expect in practice
You’ll find it performs well on wine, food and tracked-in dirt when used as part of regular maintenance. It’s especially useful if you clean frequently and want a gentle product that won’t damage fibres. For stubborn, set-in stains you may need a specialised pre-treatment or an extra pass.
Practical tips
Measure carefully you often need only small amounts per tank fill. If you’re treating pet stains or very high traffic areas, combine regular Vax maintenance with an occasional deep clean using a stronger formula for best results.
1001 Shampoo and Brush Kit 500ml
You get a compact kit with shampoo and a scrubbing brush that’s useful where machine access is limited or for targeted restoration. It’s effective on old, set-in marks when used with vigorous manual agitation.
What the kit includes and why it helps
This 500ml shampoo plus brush kit is aimed at spot cleaning and fibre restoration where using a full machine is impractical. The included brush helps you work product into the pile to lift embedded dirt.
Key benefits
Practical use cases
You should use this kit for moving-out cleans, rental touch-ups, car interiors, or where stubborn marks need local attention. Mix according to the bottle instructions, apply, then scrub with the brush, and blot or rinse as needed. Users report dramatic improvements on old marks after a determined scrub.
Limitations and advice
If you are cleaning an entire house, this smaller kit will be time-consuming; a machine concentrate will be more efficient. For very stubborn biological stains consider pairing the kit with an enzyme pre-spray. Always dry thoroughly after treatment to prevent mustiness.
Profoam Fast-Acting Stain Remover Foam
You get a foaming spot cleaner that lifts marks without soaking fibres, useful on sofas, rugs and car seats. The foam format reduces drying time and is straightforward to use for quick clean-ups.
What it does best
The foam format is designed to treat localised stains without over wetting the fabric, so it’s a good choice for upholstery, rugs and car interiors where you want faster drying.
Notable features
How to use and what to expect
Apply the foam to the stain, allow it to act briefly, then agitate with a cloth or soft brush and blot away lifted residue. Users report impressive results on older marks and on cream fabrics where wetting can be a problem. Because it’s a spray foam, you won’t need a machine this is ideal for quick interventions between full cleans.
Limitations
For ful room cleaning or very large heavily soiled areas you’ll need a machine and a larger capacity detergent. The foam is best used as a precision tool rather than a replacement for a full wash.
Dirtbusters Pet Pro Odour Neutraliser Shampoo
You’ll find this formulation aimed squarely at pet owners, with odour neutralisers and enzyme action to break down urine and other biological residues. It’s affordable and concentrates well for machine use.
Who should use it
If you have dogs or cats and need a machine safe solution that focuses on odour removal, this is designed for your needs. It contains neutralisers and cleaning agents tailored to biological soils.
Key characteristics
Performance and user tips
You’ll likely see quick improvement in odour control, especially on recent messes. For older or badly set in urine stains consider a pre treatment soak and multiple passes. Warm water can improve extraction but check your machine’s guidance first. Many users praise the smell and the balance between cleaning power and gentleness.
Limitations
Heavily contaminated fibres or long-standing biological stains may need specialist enzyme products or professional remediation. Always test on a discrete area if you have sensitive or unusual fibres.
HG Extra Strong Carpet & Upholstery Spray
You can use this spray for rapid spot treatments on carpets, clothing and upholstery; it’s oxygen-activated and removes a wide range of stains. It’s particularly handy for patching up isolated accidents without wetting large areas.
Intended use
This is a heavy duty stain spray for spot cleaning rather than whole room machine washing. You should reach for it when you need to treat wine, coffee, mud, blood or similar localised stains quickly.
Main features
Practical guidance
You’ll get the best results by spraying, leaving to work for a few minutes and then blotting or brushing away the released dirt before laundering or machine-cleaning. It’s excellent for rescuing clothing or small upholstery stains and is often used in cars for interior spots.
Cautions and tips
Always perform a patch test on an inconspicuous area before use. Avoid use on delicate textiles such as oriental rugs; for large carpeted areas this spray is uneconomic compared with machine solutions.
Practical Guide: How to Tackle Mould on Carpets
Start with safety and inspection
Before you clean, assess the scale. Small isolated patches can often be managed yourself; widespread growth or mould in the underlay needs a specialist. Always wear gloves and an appropriate mask when you disturb mould. Open windows and ventilate the room while you work.
Pre-clean and choose the right format
Remove surface debris with a vacuum (use a HEPA filter if possible). For large areas use a concentrated machine shampoo such as Pro Kleen Pro+ — it gives good economy and lifts soil when used in a hot-water extractor. For spots and edges use HG Extra Strong Spray or a low-wet foam like Profoam to avoid soaking the carpet; less water reduces the chance of left-behind moisture feeding regrowth.
Scrub, extract, then treat for spores
For stubborn, set in marks use the 1001 Shampoo and Brush Kit to agitate fibres manually before extraction. After cleaning, consider an anti mould or fungicidal rinse where labels permit. If you use BISSELL Oxy Deep Clean, you benefit from oxygen action plus a protectant to reduce future soiling useful in homes with pets or high footfall.
Drying is the most important step
Even excellent cleaning is wasted if the carpet stays damp. Use a wet vac or hot water extractor to remove as much moisture as possible. Then run fans, open windows and, if practical, use a dehumidifier. Move furniture and lift edges to let air reach the backing. Aim for full drying within 24 hours; slower drying invites mould to return.
Product care, dilution and fabric considerations
Follow manufacturer dilution rates concentrates like Pro Kleen save money but need correct dosing. Wool and delicate fibres require gentle cleaners; Vax Original Everyday Carpet Cleaner is Wool Safe approved and suitable for routine maintenance. Avoid overuse of enzymes or strong chemicals on coloured carpets without a patch test. Keep cleaning tools clean: rinse extractors, brushes and cloths after use to avoid cross-contamination.
Common mistakes to avoid
Budget vs premium approach
If you need regular maintenance and low cost: use Pro Kleen concentrate in your machine for whole house jobs. For best performance on deep contamination, choose BISSELL Oxy Deep Clean for its oxygen action and protectant. Keep HG Extra Strong or Profoam on hand for fast spot treatments and situations where you must avoid soaking.
Short checklist for a DIY mould clean:
Use this approach and you’ll reduce spores, restore appearance and limit the chance of mould returning. For anything beyond a small area, call a remediation specialist it’s the safest choice for health and for your carpet investment.
FAQ
No. Most carpet shampoos lift dirt and stains but do not reliably kill mould spores. Use a cleaner that removes organic material, follow with a fungicidal treatment if needed, and dry thoroughly. For heavy infestations, professional remediation is safer.
You should avoid bleach on most carpets. Bleach can damage fibres, strip colours and leave residues that cause further problems. Oxygen-based cleaners (like the BISSELL or HG products) are safer and effective for many stains.
Use concentrated detergents (Pro Kleen) for large area machine cleaning to save money. Use low-wet foams (Profoam) or sprays (HG) for spot treatments and quick dry times. Ready to use solutions are convenient for routine maintenance (Vax) or delicate fibres.
Dry the carpet quickly and control humidity. Use dehumidifiers, increase ventilation, repair leaks and consider a protectant product. Avoid leaving carpets damp from extractors for long periods that’s when mould returns.
Not always. Wool-safe approval (like Vax Original) means the product won’t harm wool fibres. Many carpet cleaners are safe for synthetic fibres but check labels and test a hidden area first.
Call a professional if mould covers large areas (>2 sq m), reaches the underlay or backing, the smell persists after cleaning, or household members experience health symptoms like persistent coughing or headaches.
Final Thoughts
For the toughest mouldy patches and deep seated grime, choose BISSELL Oxy Deep Clean Carpet Solution. Its oxygen boosted formula lifts deeply embedded dirt and includes a protectant to reduce future soiling, making it the best single product choice when you need a machine assisted deep clean and want to reduce the chance of mould returning.
For isolated mould spots, damp patches or fabrics you don’t want to soak, use HG Extra Strong Carpet & Upholstery Spray. It’s fast acting, oxygen activated and designed for spot treatments so you avoid over wetting a key step when fighting mould. If you must treat large areas on a budget, Pro Kleen Pro+ Concentrated Carpet Shampoo 5L is an effective, low cost concentrate that stretches far and dries reasonably well when used with a hot-water extractor.
If the mould covers more than a couple of square metres, shows black growth in the underlay or causes health symptoms, get a professional remediation specialist cleaning alone may not be enough.
