Dry Carpet Cleaning Methods That Work – And What to Watch Out For
As outlined in PAS 86:2008, the Publicly Available Specification developed by the National Carpet Cleaners Association (NCCA) and BSI British Standards, a proper carpet clean should start with a full inspection. This ensures that the appropriate method is selected based on carpet type, construction, and level of soiling. Not every carpet can withstand wet cleaning methods. For certain fibres, dry carpet cleaning offers an effective alternative when applied correctly.
The benefits of dry carpet cleaning
Some natural carpets such as jute, wool, seagrass, and sisal are sensitive to moisture and may shrink, warp, or suffer colour loss when cleaned with water. For these carpets, a carefully selected dry carpet cleaning method can reduce the risk of damage. However, it's essential to note that even dry cleaning methods can introduce moisture, and not all methods are safe for every fibre.
Dry carpet cleaning also reduces the risk of long drying times and the potential for mould growth due to residual moisture. In addition, many dry methods do not leave behind sticky residues, allowing quicker use of the carpeted area post-cleaning. Reduced water usage can also contribute to environmental sustainability when biodegradable products are used responsibly.
That said, dry carpet cleaning is not a one-size-fits-all solution and should be part of a broader maintenance plan, including regular vacuuming and periodic professional assessment.
Dry carpet cleaning methods
Dry compound
Dry compound cleaning involves applying a granular, biodegradable cleaning agent to the carpet and working it into the fibres using a mechanical brush. The compound absorbs soils and can then be vacuumed away. While effective on some synthetic carpets, this method is generally not suitable for delicate natural carpets like seagrass or sisal, as even small amounts of moisture can cause fading or warping if not used with extreme caution.
Low moisture carpet cleaning
Low moisture cleaning methods include bonnet cleaning (a rotary pad system) and solvent-based extraction. These use significantly less water than hot water extraction (HWE), but more than dry compound or encapsulation. While quicker drying, these methods still introduce moisture, and some products may not be suitable for homes with children or sensitive individuals. Always ensure solvent-based products are safe and approved for residential use.
Hire a professional carpet cleaner
Professional carpet cleaners, particularly those accredited by the NCCA, are trained to select appropriate methods based on fibre identification, carpet construction, and level of soiling. DIY attempts, especially on sensitive fibres, can easily result in permanent damage. Professionals also understand product chemistry, residue management, and drying requirements, all of which are key elements of PAS 86 recommendations.
