Laying down road or roof tar is hot, sweaty, messy work. Getting tar stains off your clothes isn't nearly as difficult but it is still going to take a bit of elbow grease and prompt attention.
How to Remove Tar Stains from Washable Clothes
Those men and women who do tar road work know that large tar stains are nearly impossible to remove and dress accordingly for their daily work. But when a small bit of tar gets on washable clothes, allow the tar to cool and harden.
If you are in a hurry, you can use an ice cube placed in a plastic bag and placed on the stain to harden the tar. When it is hardened, start by using a dull kitchen knife or the edge of credit card to scrape way as much of the solid tar pieces as possible. Next, treat the oily/waxy component of the stain with am enzyme pre-treater or stain remover like Shout. Work in the stain remover with a soft-bristled brush and allow it to sit on the fabric for at least fifteen minutes.
Next, treat the stain with a bit of heavy-duty liquid detergent that contain enough stain removing enzymes to tackle the stain (Tide and Persil are considered heavy-duty) or a paste made of powdered detergent and water. Scrub the stain lightly with a soft-bristled brush and rinse in hot water. Next, wash as usual in the hottest water suitable for the fabric according to the garment's care label.
Follow the package directions as to how much product per gallon of water. Completely submerge the garment and allow it to soak for at least eight hours. Check the stain. If it is gone, wash as usual. If it remains, mix a fresh solution and repeat. It may take several soakings to remove the stain but it should come out.
How to Remove Tar Stains from Dry Clean Only Clothes
If the garment is dry clean only, again, let the tar harden and then lift off as much of the solid tar as possible with a dull edge. As soon as possible, head to the dry cleaner and point out and identify the stain to your professional cleaner. If you are using a home dry cleaning kit, scrape off solids and be sure to treat the stain with the provided stain remover before putting the garment in the dryer bag.
How to Remove Tar Stains from Carpet and Upholstery
If a bit of tar ends up on the carpet in your car or is tracked into your home and lands on the carpet, lift away as much as possible with a spoon or dull knife. If the tar feels soft, place an ice cube or two in a plastic bag and place on the tar stain. This will cause it to harden and makes it easier to scrape from fibers.
Next, use a commercial dry cleaning solvent to treat the stain. Keeping the space well ventilated, dampen a clean white cloth or paper towel with the solution. Working from the outside edge of the stain toward the center (this helps prevent spreading the stain even larger), sponge the stain with the cleaning solution. Continue blotting until no more color is transferred from the carpet to the cleaning cloth.
When the stain is gone, dip a second clean white cloth in plain water and sponge the stain to remove any traces of the cleaning solution. If you don't do this step, the cleaning solution can actually attract more soil.
Finish by blotting with a clean dry cloth and allow the carpet to air dry. When dry, vacuum to lift carpet fibers.
The same steps can be used for all upholstery except silk or vintage fabrics. Always use the least amount of solution as possible to prevent over wetting the fabric. For silk and vintage fabrics, consult a professional cleaner.
