I put my lingerie into zippered mesh laundry bags and wash them along with other clothes in the machine; then hang dry.

Hand wash, at least the ones that need it. For the rest, delicates.

I hand wash all like ones together and then do the rest by hand as well. That is probably why my lingerie looks new for years. I have had the brocade corset for over 5 years and it still looks new.

I wash mine by hand, in the sink with Woolite or a solution of mostly water with a little of my B&BW shower gel added to it. Then I gently squeeze them in a clean towel and dry on a drying rack.

I never put lingerie in the washing machine. In fact, I rarely put my bras in the washer, I wash them the way I do lingerie. Then every other month or so, I'll get all the bras and put them into a lingerie bag and wash them on the Gentle Cycle and then press them in a towel and dry on my drying rack. Anything with elastic or under wires or push up pads never sees the inside of my clothes dryer.

I tend to wash mine in the washer with other items. I use a lingerie bag for particularly delicate items. Then I line dry, unless the care tag says otherwise.
