Carpet Fibres

POLYESTER IS

SOFT BUT

OIL-LOVING.

POLYESTER IS

AFFORDABLE

AND SOFT.

Polyester (PET) carpet is popular for its softness, vibrant colour options, and affordability. It is common in newer homes and builder-grade installations throughout Greater Victoria. But its relationship with oil creates a specific cleaning challenge.

What Is Polyester Carpet?

Polyester carpet is made from PET (polyethylene terephthalate) fibre, often recycled from plastic bottles. It is known for its exceptional softness, bright colour clarity, and stain resistance to water-based spills. Polyester is less resilient than nylon, meaning it can crush and mat in high-traffic areas. It is common in bedrooms and lower-traffic rooms in Langford, Colwood, and newer Victoria developments.

HOW POLYESTER

INTERACTS WITH

WATER AND OIL.

Fibre Behaviour

Polyester is hydrophobic (water-repelling), which means it resists water-based stains well — spills like coffee and juice tend to sit on the surface rather than penetrating the fibre. However, polyester is oleophilic (oil-loving), meaning it has a strong affinity for oily soil. Oily residues from skin, cooking, and pets can adhere to polyester fibres and are difficult to remove with water-based cleaning alone. This is why polyester carpet can develop grey traffic lanes even after cleaning.

WHAT CAN

GO WRONG?

Risks

Polyester carpet is prone to: oily soil accumulation in traffic lanes (the grey-line effect), crushing and matting in high-traffic areas (the fibre does not bounce back like nylon), and residue-related resoiling if oily soil is not fully removed. The key challenge is that water-based cleaning alone may not effectively remove oily soil from polyester — the carpet cleaning chemistry needs to be selected for the soil type, not just the fibre.

The SpeedyDry Approach

Target the oil. Clean the fibre.

SpeedyDry selects chemistry designed to address the oily soil challenge on polyester carpet. The controlled-moisture process lifts both water-based and oily soil, and thorough extraction removes both soil and solution together. For polyester carpet with persistent grey traffic lanes, a corrective assessment can determine whether the issue is oily soil, fibre crushing, or residue.
