Silk fabric, made from natural, protein-based threads, can turn
yellow for various reasons, such as exposure to sweat, improper
cleaning methods, and extended storage time.
Almost most silk garments are labeled 'recommended dry clean,' but
you can restore shine to silk at home as long as you take the
following tips.
Things You May Need When Wash
→ Plain soap flakes.
Fill a laundry tub with warm water, add one tablespoon of plain
soap sheet per gallon of water, and then dissolve the soap sheet
by hand.
Soak the item in the soapy water and gently wipe it until the
yellow areas begin to fade.
Rinse the item until all the soap removed.
→ White vinegar
Refill the tub with lukewarm water, and then add 1/4 cup of white
vinegar.
Rinse the item in the vinegar water, and then rinse it with
lukewarm water.
→Towel
Lay the garment between two thick towels and roll to squeeze out
excess water.
→Iron
Use iron of medium temperature to iron silk items. Dampen the silk
with a wet cloth before the silk begins to dry on its own before
ironing. Do not let the silk to air-dry to prevent yellowing.
Tip
Test a hidden area for colorfastness before washing.
Warning
Do not use regular laundry detergent, enzyme-based cleaners, or
chlorine bleach on silk.
Do not allow silk items to air-dry to prevent yellowing.
Do not spot-clean silk, as it can change the fabric's color and
leave permanent marks.
