How To Remove Rust Stains From Silk
Silk generally should be dry cleaned. Always follow garment label instructions when pretreating and laundering your clothes. For colored garments, test an inside seam for colorfastness.
If the garment is washable, apply a commercial rust remover, if available. Otherwise, rub with a fresh cut lemon and allow to dry in the sun, repeat if necessary. Do not use chlorine bleach on rust. Avoid cleaning silk with laundry products containing enzymes. If dry clean only, take it to the dry cleaner for stain removal.
