How to remove Tar / Asphalt from Quartz Countertop
First 60 seconds
Do not reach for a rag and start scrubbing yet. Scrape away the excess tar / asphalt from the quartz countertop, 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 an engineered stone bound with resin, so direct heat, not staining, is its main weak point.
What you'll need
- WD-40 or a similar lubricant
- A dull knife or old gift card
- Dish soap
Step by step
- Gather your materials before you start — set out everything so you are not searching mid-treatment.
- 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: mix a few drops with cold water into a light suds.
- Wipe clean with a damp cloth and dry the surface fully so no residue film is left behind.
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 quartz countertop can bond the stain permanently or warp the material.
Common questions
Can I use hot water to remove tar / asphalt from quartz countertop?
Hot water is not usually necessary, but on quartz countertop it is safer to stay with cool water regardless, since an engineered stone bound with resin, so direct heat, not staining, is its main weak point.
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.
