Lakeland Lavender Wool Wash Liquid Detergent 1L 5 "Excellent product, effective even in very cool water." Susan Becker 26 June 2019 Cleans with no residue and has a mild pleasant scent. As a previous reviewer states, can really be used for all washing, but I find it does shift colour a bit on some garment dyed items. Also produces a lot of foam in a normal wash cycle. Good test case for its' efficacy are my husbands thick Shetland wool jumpers that he'll wear for months given a chance - brown dirty water and nice clean soft jumpers. I've been using this for ages - it used to be called something else and came from Australia - anyone else remember that?
