The WoolSafe organisation is a worldwide accreditation programme for cleaning and maintenance products suitable for wool and other fibres. Products are submitted for independent testing to WoolSafe, which subjects them to a series of internationally recognised tests:
To establish that they meet recognised stadards of performance regarding cleaning, spot removal or protection against soiling or staining.
They do not have a deleterious effect on wool carpets regarding colour fastness, quick re-soling, fibre damage or odour.
They are safe to use and safe once they have been applied.
