How to remove Antifreeze from Wool
First 60 seconds
Move fast, but move carefully. Blot — do not wipe the antifreeze from the wool, working from the outside edge of the stain inward so it cannot spread any further. A brightly dyed coolant that stains porous surfaces quickly and is toxic, so gloves are worth using, and agitation and hot water cause the fibers to felt and shrink permanently.
What you'll need
- Dish soap
- Baking soda
- White vinegar
Step by step
- Test first: dab your chosen agent on a hidden corner of the wool and wait 2–3 minutes to confirm no discoloration.
- Dish soap: mix a few drops with cold water into a light suds.
- Baking soda: make a paste with water and let it sit before brushing off.
- White vinegar: mix one part vinegar with two parts water.
- Rinse and blot dry with a clean cloth, then press with dry towels and change them until no more transfers onto the towel.
Do not do this
- Ammonia-based cleaners. Mixed with certain stains it can release harsh fumes or set protein.
- Chlorine bleach. It can react with the stain or the material and cause discoloration.
- Any heat source (iron, hair dryer, tumble dryer). Heat on wool can bond the stain permanently or warp the material.
Common questions
Can I use hot water to remove antifreeze from wool?
Hot water is not usually necessary, but on wool it is safer to stay with cool water regardless, since agitation and hot water cause the fibers to felt and shrink permanently.
Is it safe to scrub the stain out?
Scrubbing usually makes things worse. Blot or lift instead of rubbing, working from the outer edge inward so the stain does not spread.
What if the antifreeze stain has already dried?
A dried stain takes longer and may need repeated treatments, but the same agents still work — just re-wet the area gently first to reactivate the stain before treating it.
