Both washing and dry cleaning damage a tutu. Do so infrequently and with care.
Try to spot clean areas rather than cleaning the whole costume.
Use a steamer to remove wrinkles and freshen a tutu. Irons should be used with great caution as too high of heat can melt netting, sequins, and damage delicate fabrics and trim.
Spray Febreeze or vodka to remove odours and kill bacteria.
Always allow costume to air dry between performances and before storing.
Using a hair dryer can speed this up between performances.
Determine what is not washable and remove.
Remove bodice from skirt and wash or clean separately.
Hoops covered with buckram (rather than plastic) will need to be removed to wash. With time hoops will rust and the buckram will disintegrate.
When washing a tutu skirt (remove bodice, clean separately), wash in a bathtub with cool water and mild soap. Thoroughly rinse then air dry.
Try to maintain the shape of the skirt while laundering:
Classical tutus—dry flat
Romantics—hang to dry
Try to find a cleaner that is cleaning costumes and inform them of all know fibres, trims and glues used.
Dry cleaning solvents may damage some sequins and stones, ASK first!
