Have washed with very little detergent, the part just for 15 minutes (short cycle, 15 minutes) at 30 degrees.
For safety first in a laundry net (for nerds: Because normally your bras women in it, so they do not destroy the washing machine - or vice versa)!
2. Then in the dryer (early stage)
3.Ergebnis: Like new! Perfect! Goes without washing bag ...
4.Ohne guarantee ;-)
5.Kaufempfehlung!
