HARMONY WoolSafe is a professional acidic carpet and upholstery rinse formulated at pH 2 to neutralise alkaline residues and restore fibre balance after cleaning.
After high-alkaline detergents or powder-based products are used, fibres can remain chemically unstable. This can lead to browning, yellowing or texture distortion. HARMONY WoolSafe corrects this by restoring pH balance, stabilising fibres and protecting carpets, upholstery and rugs where fibre safety is critical.

Helps prevent browning and yellowing

Works as a rinse, in-tank cleaner or acidic pre-spray

Best acid rinse / neutraliser I’ve ever used. Smells great and also cleans which was surprising. I use this every day but have also used it on wool rugs as an extractor without spraying first. 10/10

Njord Harmony is one of the most versatile and reliable neutral detergents I’ve used. It delivers a beautifully balanced clean — gentle on fibres but still powerful enough to lift everyday soils with ease. The scent is fresh, subtle, and leaves textiles smelling genuinely clean without being overpowering.
In my Rug Spa, Harmony has become a go-to. It performs brilliantly on delicate and premium rugs where pH control is crucial, giving me consistent, safe results every single time. Whether it’s pre-scrubbing, washing, or final rinse work, Harmony fits perfectly into the workflow.
A superb all-round product that truly lives up to its name.

This is amazing as a rinse when using strong pre spray chemicals like Njordfire or NjordHammer. Another chem you don’t want to get caught out with not having on your van.
