How to Get Tar Out of Loofah: Fast Proven Methods

By James Kowalski · December 23, 2025

Immediate Action (first 5 minutes)

I was elbow-deep in the undercarriage of my 1982 Jeep CJ7 last weekend. The frame was caked in decades of road tar and grime. I grabbed my heavy-duty natural Egyptian loofah to scrub the black gunk off my forearms. Big mistake. I dropped the $18 bath sponge right into a fresh puddle of driveway sealer and melted pitch. If you've ever wondered how to get tar out of loofah, you're probably in a similar messy situation right now.

Stop. Don't run it under hot water. Heat makes petroleum-based tar viscous and sticky. It will sink deeper into the porous gourd fibers and permanently ruin the sponge. You need to act fast. But you must use cold.

Grab a dull plastic scraper or a butter knife. Gently lift away the thickest clumps on the surface. Do this over a trash can to avoid staining your sink. Next, run the loofah under the coldest tap water you have for exactly 60 seconds. This drops the surface temperature and stops the tar from migrating. Pat it dry with a paper towel. You've bought yourself time. Now we can actually fix this.

What You'll Need (tools/products)

You can't just throw a tar-stained loofah in the washing machine. The tar will melt, ruin your machine, and destroy your clothes. I've tested dozens of solvents in my garage over the last 12 years. Some melt the sponge. Others just smear the stain. Here is the exact toolkit you need to save your loofah.

Before we start, let's address the type of loofah you have. If you are using a synthetic plastic mesh pouf (the $3 puffy ones), throw it in the trash. Solvents will melt the plastic mesh into a toxic blob. This guide is for natural fibrous gourd loofahs, which are resilient and worth the $15-$25 effort to save.

Citrus Solvent: De-Solv-it Pro Strength ($12.99 for 12 oz). This is my absolute favorite because d-Limonene breaks down petroleum without destroying natural fibers.
Freezer Space: You need a standard kitchen freezer set to 0°F.
Scrubbing Brush: OXO Good Grips Palm Brush. The stiff synthetic bristles get deep into the gourd mesh without tearing it.
Degreasing Soap: Dawn Platinum Powerwash Dish Spray. The surfactants in this specific formula lift oily residue better than standard hand soap.
Containment: A heavy-duty gallon Ziploc bag and a plastic bucket.

Solvent Type	Brand Example	Effectiveness on Tar	Safety for Natural Loofah
Citrus Extract	De-Solv-it	Excellent	Very High
Mineral Spirits	Klean-Strip	Excellent	Moderate (Dries fibers)
Penetrating Oil	WD-40	Good	High (Leaves oily residue)
Bleach	Clorox	Zero	Destructive

Step-by-Step Removal

I'll be honest, this takes elbow grease. Tar is essentially liquid asphalt. It bonds to the microscopic ridges of the dried gourd. Follow these steps exactly, and you won't have to buy a replacement.

Step 1: The Deep Freeze

Place your scraped loofah inside the gallon Ziploc bag. Squeeze out as much air as possible and seal it tight. Put it in your freezer for exactly 45 minutes. The goal here is to drop the internal temperature of the tar below its glass transition point, which is usually around 20°F. When my wife asked why there was a dirty sponge next to the frozen peas, I told her it was science. Freezing makes the tar brittle instead of sticky.

Step 2: The Snap and Scrape

Pull the loofah out of the freezer. You have about a 3-minute window before the tar warms up and gets gummy again. Put on a pair of nitrile gloves. Flex the loofah aggressively in your hands. You will hear a cracking sound. That is the frozen tar shattering inside the fibers. Use your dull butter knife to pick out the larger black shards. Discard them in the trash.

Step 3: Solvent Soak

Move to your garage or a well-ventilated patio. Place the loofah in your plastic bucket. Spray the De-Solv-it Pro Strength directly onto the remaining stained areas. Saturate it completely. Let it sit for 8 to 10 minutes. The d-Limonene needs time to break the chemical bonds of the petroleum. Don't let it dry out. If it looks dry after 5 minutes, spray it again.

Step 4: Agitation

Grab your OXO Good Grips Palm Brush. Scrub the loofah in circular motions, pressing firmly to push the bristles deep into the mesh. You will see the solvent turning dark brown or black. This is the tar emulsifying. Flip the loofah over and repeat on the other side. This step usually takes about 4 minutes of continuous scrubbing.

Step 5: The Dawn Degrease

The citrus solvent has lifted the tar, but now your loofah is coated in oily residue. Rinse it briefly with warm water (around 105°F). Spray the Dawn Platinum Powerwash generously all over the sponge. The surfactants in Dawn will encapsulate the oily solvent molecules. Massage the soap into the fibers with your hands for 2 full minutes. Rinse under the warm tap until the water runs completely clear and the suds disappear.

Step 6: Air Dry and Inspect

Squeeze out the excess water. Do not wring it like a rag, or you will snap the natural fibers. Press it between two clean microfiber towels. Hang it in a dry, well-ventilated area away from direct sunlight. It will take about 12 to 18 hours to dry completely. Once dry, inspect it under a bright LED light. If you see tiny black specks that feel hard, those are likely just natural gourd seeds, not tar.

Alternative Methods

Sometimes you don't have a citrus solvent on hand. Or maybe the tar is an older, hardened asphalt patch that refuses to budge. I've tested these backup methods when the De-Solv-it didn't quite finish the job.

Backup Method 1: Gojo Fast Orange Pumice

If you work on cars, you probably have a pump bottle of Gojo Fast Orange hand cleaner in your garage. The pumice particles act as a micro-abrasive, while the citrus oils break down grease. Pump a generous amount directly onto the dry, tar-stained loofah. Rub the fibers together vigorously for 5 minutes. The pumice will physically scrape the tar out of the deep crevices. Rinse thoroughly with hot water. This isn't the cheapest option, but it works incredibly well for mechanics.

Backup Method 2: The Pantry Oil Soak

Tar is oil-soluble. This means other oils can dissolve it. If you are in an apartment and only have kitchen supplies, grab a bottle of cheap olive oil or melted coconut oil. Submerge the stained section of the loofah in a bowl of oil. Let it soak for 2 hours. The oil will slowly soften the tar. After soaking, use a stiff brush to agitate the fibers. You will need to wash it with Dawn dish soap three or four times to get all the cooking oil out afterward.

Backup Method 3: WD-40 Specialist Degreaser

Don't use standard WD-40. The standard formula leaves a terrible smell that will linger in your shower for weeks. Instead, use WD-40 Specialist Industrial-Strength Degreaser. Spray it on the tar spots and let it sit for 15 minutes. The industrial solvents are much harsher than citrus, so keep an eye on the loofah. If the natural fibers start looking frayed or mushy, rinse it immediately. This method is highly effective but slightly risky for older, brittle loofahs.

Prevention Tips

After spending an hour scrubbing pitch out of a bath sponge, you'll want to avoid doing it again. Here are a few rules I now follow in my shop.

Establish Garage Boundaries: Never bring bathroom items into the garage. Keep a dedicated $5 stiff-bristle nail brush in your shop specifically for scrubbing grease and tar off your hands. It's easier to clean and won't ruin your shower routine.
Use Barrier Creams: Before working on a tar-heavy job, apply a barrier cream like Gojo Skin Conditioner or Invisible Glove. This creates a microscopic shield on your skin. The tar sticks to the cream, not your pores, meaning you only need a light wipe with a paper towel instead of an aggressive loofah scrubbing session.
Pre-Treat Your Tools: If you must use a specific sponge for automotive work, spray it with a light coat of silicone spray or cooking oil before starting. The tar won't bond to the pre-oiled fibers, making cleanup a simple 30-second rinse.

FAQ

Can I use bleach to remove the tar stain?

Bleach will absolutely not dissolve petroleum-based tar. It will only degrade the natural fibers of your loofah and leave you with a brittle, useless sponge. Stick to citrus-based solvents or heavy-duty degreasers for actual tar removal.

Will this method ruin a synthetic plastic loofah?

Yes, strong solvents like mineral spirits or industrial degreasers will melt synthetic plastic mesh. If you are using a cheap $3 plastic pouf, just throw it away and buy a new one. This guide is specifically designed to save natural fibrous gourd loofahs.

How do I know if the tar is completely gone?

Run your fingers through the damp fibers and feel for any hard, sticky nodules. If the loofah feels completely uniform and smells only like dish soap, you are finished. Any remaining black specks that feel rough are likely just natural gourd seeds, not tar.

Is it safe to use the loofah on my skin after cleaning?

Yes, as long as you complete the final Dawn dish soap wash to strip away all solvent residue. I recommend letting it dry completely for 24 hours so any lingering volatile organic compounds can evaporate. Once it is dry and smells fresh, it is perfectly safe for your next shower.
