Proven Ways: How to Get Tar Out of Denim Jeans (2026)

Immediate Action (first 5 minutes)

Stepping in fresh asphalt or driveway sealer is a sinking feeling. I know that panic well. If you are wondering how to get tar out of denim jeans, the clock starts ticking the exact second that black blob hits your fabric. Denim is woven in a diagonal twill pattern, which creates tiny ridges that act like traps for sticky petroleum products. When tar is warm and pliable, it sinks deep into those cotton grooves.

Your absolute first move is to stop walking and avoid the urge to wipe it. Wiping wet tar just smears the petroleum compounds across the surface and pushes them deeper into the warp and weft threads. I ruined a pair of vintage Levi's 501s back in 2019 by trying to scrub a fresh tar spot with a paper towel. Don't make my mistake. Instead, you need to change the physical state of the stain immediately.

Grab an ice cube from your freezer or a cold drink from the fridge. Press the ice directly against the tar for about 60 to 90 seconds. The goal here is to drop the temperature of the tar below its hardening point, which is usually around 70°F (21°C). Once the tar turns brittle and opaque, it stops bonding with the cotton fibers. This crucial five-minute window is the difference between a minor annoyance and a permanently ruined pair of pants.

What You'll Need (tools/products)

Gathering the right supplies before you start makes this process infinitely smoother. I've tested dozens of household items on my own workwear over the last decade. Here is the exact kit I recommend keeping in your laundry room for petroleum-based stains.

Step-by-Step Removal (4-7 steps)

Now that your tar is frozen and your supplies are ready, we can tackle the stain. I'll be honest, this takes a bit of elbow grease, but it is highly effective.

Step 1: Freeze and Scrape

Apply your ice pack until the tar is completely hard to the touch. Take your dull butter knife and gently scrape the surface. Work from the outside edges of the stain toward the center. You should see the brittle tar flake off in small chunks. Pick these chunks up with your fingers and throw them in the trash. Do not rinse the jeans yet.

Step 2: Apply the Citrus Solvent

Saturate the remaining tar residue with your Goo Gone or similar citrus solvent. The d-limonene in citrus oils is a natural degreaser that breaks the chemical bonds of petroleum. Let the solvent sit on the stain for exactly 10 to 15 minutes. If you are working on a heavy-duty pair of Carhartt jeans, you might need to let it sit for 20 minutes.

Step 3: Blot and Agitate

Take your soft-bristle brush and gently work the solvent into the fabric using small circular motions. You will see the black stain start to turn brown and liquefy. Immediately press a clean white rag against the area to absorb the dissolved tar. Repeat this brush-and-blot cycle until the rag comes away mostly clean. This usually takes about three or four passes.

Step 4: Degrease with Dish Soap

The tar is gone, but your jeans now have a massive grease spot from the solvent. Spray the area generously with Dawn Powerwash. Rub the fabric against itself gently to work the soap into the fibers. Let the dish soap sit for 5 minutes to emulsify the remaining citrus oils.

Step 5: Wash in Cold Water

Put your jeans in the washing machine by themselves. Wash them on a normal cycle using cold water, ideally around 60°F to 70°F (15°C to 21°C). Add your regular laundry detergent. Do not wash them with other light-colored clothing, as the dissolved tar and indigo dye could transfer during the agitation cycle.

Step 6: Air Dry and Inspect

Hang your jeans to air dry. Never put them in a hot dryer until you are 100% certain the stain is completely gone. The high heat of a dryer (often exceeding 130°F) will bake any microscopic tar remnants permanently into the cotton. Once dry, inspect the area in bright natural light. If you see a faint shadow, repeat steps 2 through 5.

Alternative Methods (2-3 backup methods)

Sometimes you don't have commercial solvents on hand, or you are dealing with a delicate raw denim that might react poorly to strong chemicals. Here are two backup methods I've used successfully in a pinch.

Method 1: The Peanut Butter Trick

This sounds crazy, but it actually works. The natural oils in creamy peanut butter (do not use crunchy, as the nut pieces will get stuck in the weave) act as a mild solvent for petroleum. Smear a thick layer of peanut butter over the hardened tar. Let it sit for 30 minutes. The oils will slowly penetrate and soften the tar. Scrape it off with your butter knife and follow up immediately with Dawn dish soap to remove the peanut oil. This isn't the fastest option, but it is incredibly safe for dark dyes.

Method 2: Mineral Spirits for Heavy Workwear

If you are cleaning thick, double-knee work pants and the tar is deeply embedded, mineral spirits like Klean-Strip will obliterate it. Dampen a rag with mineral spirits and dab the stain. This stuff is highly volatile and smells terrible, so you must do this outside or in a heavily ventilated garage. Mineral spirits can strip the indigo dye right out of fashion denim, so reserve this strictly for rugged workwear where fading isn't a concern.

Method Cost Effectiveness Risk to Denim Dye
Citrus Solvent (Goo Gone) $6 - $8 High Very Low
Peanut Butter $3 - $5 Medium None
Mineral Spirits $10 - $14 Very High High (Fading)

Prevention Tips

Avoiding the stain in the first place is always easier than scrubbing it out later. If you are doing driveway sealing or roofing work, wear a dedicated pair of throwaway painter's pants over your good denim. For road cyclists who constantly get 'tar flick' on the back of their calves from hot summer roads, I highly recommend investing in a pair of lightweight cycling gaiters or applying a fabric guard spray like Scotchgard Heavy Duty Water Shield before your ride. The fluoropolymer coating creates a slick barrier that makes fresh tar much easier to wipe off before it sets.

FAQ

Can I use hot water to melt the tar out of my jeans?

No, hot water will actually set the petroleum compounds deeper into the cotton fibers. You should always use cold or lukewarm water when washing denim treated with solvents. Hot water also causes the indigo dye to bleed, which ruins the look of your jeans.

Will Goo Gone bleach or fade my dark denim?

Goo Gone is generally safe for most denim dyes, but it can sometimes lighten very dark or raw indigo jeans. I always recommend testing a tiny drop on the inside hem and waiting 10 minutes to check for color transfer. If the cloth comes away blue, switch to a milder oil-based method like peanut butter.

What if the tar stain has been sitting there for months?

Dried, aged tar requires a much longer soaking time to break down the hardened petroleum bonds. You will need to apply your solvent and let it sit for at least 45 minutes before scraping. I'll be honest, this takes serious elbow grease, and you might need to repeat the solvent process two or three times.

Can I just take my tar-stained jeans to the dry cleaner?

Most professional dry cleaners can handle tar stains using industrial-grade perc solvents. However, they often charge between $15 and $25 per garment for specialized spot treatment. You must point out the exact location of the tar and tell them what home remedies you have already tried.
