Treat complex carpet stains

Assessment tool

Version 1.0
Issue Date: April 2024


This unit of competency specifies the outcomes required to remove complex stains from carpets after standard stain removal and cleaning techniques have failed. It covers selecting and preparing required equipment and chemicals, and applying complex stain removal techniques to the task.

The unit supports carpet cleaners who work alone or in teams. It applies in a range of commercial and residential work sites. Removing stains is undertaken as a separate task or in conjunction with other cleaning methods, such as vacuuming, extraction and general cleaning.

No licensing, legislative, regulatory, or certification requirements apply to this unit of competency at the time of endorsement.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
