The use of technical fibres in exercise/swim/adventure clothing has dramatically increased over the past few years. Although some of these can be washed by machine, manufacturers are still recommending that you use a delicate soap to help preserve the integrity of the fibre and keep it looking and performing like new.
Simply follow these directions or the directions on the bottle. Eucalan has no bleach, phosphates, dyes or synthetic scents. It is a gentle formula that will not break down the fibres or dull the colours. The lavender or grapefruit scent might be preferable as those essential oils have natural antiseptic properties.
