Your Symbi suit can be machine washed, but please follow the guidance below for best results and to avoid damage of colour run on your suit.
Wash on a cold (40°C or lower) wash
Use a non-bio, soft detergent (e.g. pure soap powder)
Wash alone in case colours run
Turn inside out, and place inside a pillowcase or bag if you have coolmax lining to ensure the suit does not catch on anything
Don't forget to empty your pockets!
Use a gentle spin on your washing machine
Do not tumble dry!
Hang out to dry in a warm dry place (e.g. airing cupboard)
