How to remove Antifreeze from Spandex / Lycra
First 60 seconds
The first sixty seconds decide how this turns out. Blot — do not wipe the antifreeze from the spandex / lycra, 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 the elastane fibers lose their stretch permanently if exposed to high heat or harsh solvents.
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 spandex / lycra 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.
- Wipe clean with a damp cloth and dry the surface fully so no residue film is left behind.
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 spandex / lycra can bond the stain permanently or warp the material.
Common questions
Can I use hot water to remove antifreeze from spandex / lycra?
Hot water is not usually necessary, but on spandex / lycra it is safer to stay with cool water regardless, since the elastane fibers lose their stretch permanently if exposed to high heat or harsh solvents.
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.
