Knitted garments in merino wool & silk:
Wash by hand at 30˚C with a neutral detergent for wool. Spin, but never tumble-dry. Dry flat. Steam the garment. Never allow garments to soak. It is a good idea to wash merino wool/silk garments after the first wearing to get the fibres to bond better, thus reducing the risk of pilling. Dry cleaning, see label.
