01 The short answer
To get drool out of silk, work in this order: (1) soak in wool wash; (2) delicate fabric: approved care only; (3) persistent colour: professional advice. On silk, skip enzyme ("bio") detergent and oxygen bleach: protease enzymes digest protein, and silk is protein. Use an enzyme-free wool wash. Rinse in cool water, roll in a clean towel to press out water, and dry flat or on a padded hanger out of the sun.
Consult a professional experienced with this material. The difficulty rating does not establish that a home method will work.
02 Never do this
- Enzyme ("bio") detergent. Protease enzymes digest protein, and silk is protein. Use an enzyme-free wool wash.
- Oxygen bleach (OxiClean-type powder). Alkaline peroxide damages wool, cashmere and silk; the packs say so.
- Chlorine bleach. Chlorine bleach can destroy wool or silk fibres, not merely change the stain colour. Do not use it on this material.
- The dryer before it is gone. Dryer heat locks in whatever is left. Air-dry and check first.
03 Before you start
- Use white cloths or paper towels only: coloured ones can transfer their own dye into silk.
- If the label says dry clean only, do not use this home washing method: take it to a professional. For washable delicates, use a product specifically labelled for the fabric.
- Pretest every permitted treatment on an inconspicuous area, including trims, and let it dry. Stop for colour transfer, lightening, rings, stiffness or distortion. A successful spot test does not guarantee the whole item is safe.
04 The method
Soak in wool wash
Only if the item care label permits washing: use a detergent explicitly labelled for this fabric at its stated dilution, temperature and contact time. Handle gently and rinse as directed. Do not substitute ordinary enzyme detergent or extend soaking to chase a persistent mark; consult a professional if a compatible gentle wash does not work.
Why it works: A pH-neutral wool wash loosens protein and soil without attacking the fibre itself.

Delicate fabric: approved care only
Only if the item care label permits washing: use a detergent explicitly labelled for this fabric at its stated dilution, temperature and contact time. Handle gently and rinse as directed. Do not substitute ordinary enzyme detergent or extend soaking to chase a persistent mark; consult a professional if a compatible gentle wash does not work.
Why it works: Generic home recipes do not establish compatibility with delicate fibres, dyes, linings or finishes.
Persistent colour: professional advice
Stop after a fabric-approved gentle wash if colour remains. Do not substitute a homemade peroxide treatment for a prohibited oxygen-bleach product; ask a professional cleaner.
Why it works: A product being less alkaline does not establish that it is safe for this garment or dye.
Rinse, roll, dry flat
Rinse in cool water, roll in a clean towel to press out water, and dry flat or on a padded hanger out of the sun.
Why it works: Silk is weak when wet and yellows in sun.

05 Dried, set, or back again?
- For a dried stain, use only a detergent specifically labelled for this fabric, at its stated dilution and contact time, and only if the care label permits washing. Do not substitute ordinary enzyme detergent on wool or silk. If it persists, consult a professional rather than increasing the strength or soaking time.
- Old oil has partly oxidised and gone sticky; apply the degreasing step two or three times, and give powder an overnight stay where it is used.
Oil is often invisible on damp fabric and shows again once dry. Check in daylight after air-drying and repeat the degreasing step before any heat.
06 What drool is made of
- Oil and fat
- Protein
- Dye
The oily part of drool will not dissolve in water at all. It needs a surfactant such as dish soap, or a solvent, to break it up, and a dry powder can draw fresh oil out before you start.
Drool can include protein. Heat can make protein-containing stains harder to remove. On washable materials, cool water is a common first step. A protein-digesting detergent is an option only when its label permits the actual fabric; use a suitable delicate-fabric detergent on wool or silk.
Drool carries dye that soaks into fibres rather than sitting on them. Depending on the dye, alcohol dissolves it, oxygen bleach breaks it down, or sunlight fades it, and speed matters more than strength.
- Saliva contains amylase and proteins; together with sweat, skin oil and hair products, it oxidises to the yellow patch on pillows over weeks.
- Silk pillowcases show drool rings easily: water alone leaves a tide line on silk.
07 The material: silk
Silk can be wetted, but gently: dab, swish and press, never wring or scrub.
No rubbing at all; every step is a press-and-lift.
Soak only if the garment and fabric-specific detergent labels permit it, using their dilution and contact time. Ordinary enzyme detergent and alkaline oxygen-bleach powder are not substitutes for a wool- or silk-compatible wash.
Water stays at or below 30 °C (86 °F) the whole way through.
What this file leaves out because of the material:
- Enzyme ("bio") detergent. Protease enzymes digest protein, and silk is protein. Use an enzyme-free wool wash.
- Oxygen bleach (OxiClean-type powder). Alkaline peroxide damages wool, cashmere and silk; the packs say so.
- Silk is a protein fibre, so it shares wool's weaknesses: no enzymes, no chlorine, no alkaline soaks and no hot water.
- Wet silk and its dyes require careful handling. Rubbing can cause chafing, colour loss or surface distortion; the exact strength change depends on the fabric.
The silk file rates every common cleaner for it.
08 Next time
Use pillow protectors under pillowcases and wash pillowcases weekly; silk pillowcases show drool rings more than cotton.
09 Questions
Can I use hot water on drool on silk?
Keep it cool: silk itself does not tolerate water above about 30 °C (86 °F), whatever the stain.
Does vinegar help with drool on silk?
It is not needed for drool. Vinegar is a mild acid that helps with tannin and mineral residue; drool responds better to enzyme-free wool wash.
Can I use bleach on drool?
Not chlorine bleach. Chlorine bleach can destroy wool or silk fibres, not merely change the stain colour. Do not use it on this material.
Will drool come out of silk completely?
Consult a professional experienced with this material. The difficulty rating does not establish that a home method will work.
When should I call a professional?
Anything valuable, structured or dry clean only, and every stain bigger than a coin on a special-occasion piece. For this stain in particular, a professional cleaner (tell them it is drool) has solvents and spotting agents that home kits do not.
What if it has already dried or been through the dryer?
For a dried stain, use only a detergent specifically labelled for this fabric, at its stated dilution and contact time, and only if the care label permits washing. Do not substitute ordinary enzyme detergent on wool or silk. If it persists, consult a professional rather than increasing the strength or soaking time. Old oil has partly oxidised and gone sticky; apply the degreasing step two or three times, and give powder an overnight stay where it is used.
