How to remove Tar / Asphalt from Cork Flooring
First 60 seconds
Do not reach for a rag and start scrubbing yet. Scrape away the excess tar / asphalt from the cork flooring, lifting solids off the surface without pressing them further in. A petroleum-based residue that softens with a lubricant before it will lift instead of smear, and a naturally spongy material that absorbs liquid fast through its sealed surface if it sits too long.
What you'll need
- WD-40 or a similar lubricant
- A dull knife or old gift card
- Dish soap
Step by step
- Test first: dab your chosen agent on a hidden corner of the cork flooring and wait 2–3 minutes to confirm no discoloration.
- WD-40 or a similar lubricant: spray lightly, wait a minute, then wipe from the outside in.
- A dull knife or old gift card: scrape gently at a low angle, never digging in.
- Dish soap: work a tiny amount into the spot on a barely-damp cloth, then wipe off immediately — do not saturate the material.
- Rinse and blot dry with a clean cloth, then press with dry towels and change them until no more transfers onto the towel.
- If a visible mark remains after two attempts, stop — further scrubbing on this material risks permanent damage, and a professional cleaner is the safer next step.
Do not do this
- Hot water as a first step. It spreads oil-based stains before they can be lifted.
- Rubbing the spot. It pushes the stain deeper and spreads it outward.
- Any heat source (iron, hair dryer, tumble dryer). Heat on cork flooring can bond the stain permanently or warp the material.
- Soaking the cork flooring. Oversaturating this material causes water rings, warping, or permanent staining of its own.
Common questions
Can I use hot water to remove tar / asphalt from cork flooring?
Hot water is not usually necessary, but on cork flooring it is safer to stay with cool water regardless, since a naturally spongy material that absorbs liquid fast through its sealed surface if it sits too long.
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 tar / asphalt 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.
