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.

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.

BISSELL Oxy Deep Clean Carpet Solution

Best for intensive deep cleaning
9.2/10
EXPERT SCORE

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.

Amazon price updated: January 23, 2026 6:21 am
Pros
Excellent stain-lifting performance on deep grime
Contains Scotchgard protector for future stain resistance
Good foaming action for pile agitation and extraction
Compatible with most full-size carpet washers
Cons
Requires some elbow grease for best results
Higher price than basic everyday solutions

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

Contains Scotchgard protector to guard against new stains
Oxygen boosted formula for stronger stain lift
Safe for use in BISSELL and most full-size upright carpet washers

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

Best value concentrate for large areas
9/10
EXPERT SCORE

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.

Amazon price updated: January 23, 2026 6:21 am
Pros
Very economical concentrate — large 5L supply
Effective on pet odours and general grime
Safe for use in most machines and upholstery
Revives pile and colour on older carpets
Cons
Bottle can be heavy to pour when full
Requires correct dilution to avoid residues

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

Ultra-concentrated 4-in-1 formula for carpets and upholstery
Targets odours, lifts dirt and rejuvenates fibres
Works with a wide range of carpet cleaning machines

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

Best for regular, everyday maintenance
8.5/10
EXPERT SCORE

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.

Amazon price updated: January 23, 2026 6:21 am
Pros
Affordable and effective for routine cleaning
Pleasant Rose Burst fragrance that neutralises odours
Wool safe formulation for delicate carpets
Works well at normal machine dilution rates
Cons
Less aggressive on very deep, set in stains
May require repeat passes on heavy soiling

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

Wool Safe approved for delicate fibres
Neutralises household odours rather than simply masking them
Suitable for use in most carpet cleaning machines and for manual spot cleaning

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

Best for manual scrubbing and spot restoration
8.3/10
EXPERT SCORE

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.

Amazon price updated: January 23, 2026 6:21 am
Pros
Includes brush for manual agitation and spot work
Effective on old and set in stains when scrubbed
Economical dilution rates and easy to store
Cons
Requires physical scrubbing effort for best results
Smaller bottle not ideal for whole house machine washes

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

Enzyme and surfactant mix to target stains
Comes with a brush for targeted scrubbing and agitation
Works on rugs, upholstery and small carpet areas

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.


5

Profoam Fast-Acting Stain Remover Foam

Best for low-wet foam spot cleaning
8.2/10
EXPERT SCORE

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.

Amazon price updated: January 23, 2026 6:21 am
Pros
Low-wet foam reduces over saturation and faster drying
Effective on pet urine, mud, wine and food stains
Safe on many fabrics and suitable for cars and sofas
Cons
Smaller canister makes it less cost effective for big jobs
Requires scrubbing for very stubborn stains

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

Fast acting foam lifts a range of common stains
Gentle formulation aimed at household and pet messes
Made in the UK and intended for spot treatment

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.


Pet Odour Neutraliser
6

Dirtbusters Pet Pro Odour Neutraliser Shampoo

Best focused formula for pet stains and smells
8/10
EXPERT SCORE

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.

Amazon price updated: January 23, 2026 6:21 am
Pros
Formulated specifically for pet stains and odours
Concentrated stretches to many fills when diluted
Pleasant, non offensive fragrance
Suitable for most carpet cleaning machines
Cons
May need repeat treatments on older, set in urine stains
Some users prefer different fragrance profiles

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

Concentrated pet carpet shampoo that dilutes for machine use
Targets urine, faeces and pet related odours
Designed to be safe for regular use in carpet cleaners

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

Best for quick spot and stain removal
8/10
EXPERT SCORE

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.

Amazon price updated: January 23, 2026 6:21 am
Pros
Powerful oxygenated action removes many tough stains
Convenient spray bottle for targeted treatment
Good for fabrics and car upholstery when tested first
Cons
Not suitable for delicate oriental rugs or some textiles
Large areas would need much product better as spot cleaner

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

Active oxygen formula lifts ingrained stains
Spray applicator for direct treatment
Suitable for many fabrics (patch test recommended)

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

Over wetting carpets with pump sprays or extractors and leaving them to dry slowly.
Using bleach or harsh solvents that damage fibres or backings.
Skipping a follow up drying period or failing to address the humidity source.
Treating structural moisture problems with cleaning alone fix leaks and damp before re laying carpets.

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:

Inspect and isolate the affected area.
Vacuum to remove surface spores.
Pre-treat stains with a spot product (HG or Profoam).
Machine-clean with BISSELL Oxy Deep Clean or Pro-Kleen; scrub with 1001 kit if needed.
Extract moisture thoroughly and dry with fans/dehumidifier.
Apply a suitable protectant or fungicidal treatment if recommended.

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

Will carpet shampoo alone kill mould?

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.

Can I use bleach on mouldy carpet?

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.

Which format is best: foam, concentrate or ready-to-use?

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.

How do I stop mould coming back after cleaning?

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.

Is carpet-safe the same as wool-safe?

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.

When should I call a pro instead of DIY cleaning?

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.
