What can dissolve tar?

Soak a rag with either mineral spirits or kerosene and rub off the tar that remains. They are solvents that easily dissolve tar, but they give off dangerous fumes, so wear a respirator and keep the windows open while using them.

Do tar stains come out?

Tar and asphalt stains are oil stains, so you need an enzyme laundry detergent to remove them. Pour the enzyme laundry detergent directly onto the stain. Use a towel or paper towels to tamp the stain by pressing firmly on the stain and then lifting the towel back up.
