Choosing between dry-compound and wet-cleaning methods
Dry compound, often called 'low moisture,' versus traditional wet extraction: which is appropriate for your commercial carpet?
Understand when to use dry-compound cleaning versus wet extraction
There is a common misunderstanding that 'dry' cleaning is always better because there's no water. In reality, both dry-compound and wet-cleaning methods have their place in a professional maintenance programme.
Choosing the right one is about understanding the nature of your carpet, the soiling you face, and the speed you need to reopen.
For buildings that never fully close, the practicalities of running a wet-cleaning process around live staff and visitors deserve as much attention as the cleaning result itself.
Noise, odour and physical disruption all factor into which method is genuinely workable on an occupied site, not just which one cleans more deeply on paper.
- Dry-compound uses absorbent powder to lift soil.
- Wet-extraction uses water to flush soil out.
- Wet-cleaning is best for deep, heavy soiling.
- Dry-compound is ideal for sensitive or delicate fibres.
- Always balance drying speed against cleaning depth.
- Occupied sites often need to weigh disruption alongside cleaning depth.
- Odour from damp carpet can affect staff comfort for hours after cleaning.
Dry-Compound: Controlled Cleaning
This uses specialised powders that contain cleaning agents. The powder is worked into the carpet, absorbs the dirt, and is then vacuumed out.
It is completely dry, meaning there is no downtime. It's exceptionally safe for delicate carpet tiles or areas with poor air circulation.
Wet Extraction: High Performance
Traditional wet cleaning (HWE) is the gold standard for removing deep-set dirt and pollutants. Water and soap are pushed into the pile and vacuumed away.
It is vastly more effective at removing heavy, oily, or caked-on dirt, but it does require careful drying time.
- Dry: zero downtime
- Wet: deeper cleaning efficiency
- Dry: safer for delicate fibres
- Wet: standard for high-traffic restorative work
Making the call
If your office is in a high-rise with little ventilation, or you have unique carpet types, dry-compound is often the safer, more practical choice.
For high-traffic, reception areas or heavy-duty industrial carpets, nothing matches the power of wet extraction.
Suitability for occupied buildings
Wet extraction machinery is louder and requires cordoning off areas, which can be disruptive in open-plan offices where staff are working nearby.
The characteristic 'wet carpet' smell that lingers during drying can be unwelcome in customer-facing areas such as receptions or waiting rooms, even when the cleaning itself is entirely effective.
Dry-compound methods produce no odour and require minimal cordoning, making them a practical choice for spaces that genuinely cannot be closed off, even briefly, during business hours.
Why businesses ask us for this
- • Wet extraction is for deep cleaning.
- • Dry compound is for delicate fibres and zero-downtime needs.
- • Both are valuable tools in a maintenance cycle.
- • Consider noise and odour disruption alongside cleaning depth.
- • Dry-compound suits spaces that can't be closed off at all.
- • Out-of-hours scheduling can resolve most disruption concerns.
