Don’t take antique clothing to a regular dry cleaner. The chemicals dry cleaners use are too harsh, and their pressing techniques stress the fabric too much. If you really need professional help, find a dry cleaner that specializes in old fabrics.
The safest way to clean fragile garments is to give them a sponge bath.
But before you start, fix any tears in the fabric-otherwise, the stress of cleaning will make matters worse.
Then mix a squirt of mild detergent in 1 gallon (3.8 ml) of lukewarm water and dab the solution on gently with a sponge.
Rinse by sponging on clean water.
Try not to completely soak the garment.
