For a slightly stronger mixture, use one part dish detergent and two parts hydrogen peroxide.
Before you apply the soap-and-peroxide mixture, place a towel inside of the garment to keep the stain from transferring to the other side. This way, the towel will absorb the stain. If you don’t want to massage the stain with your hands, or if the fabric is particularly delicate: you can blot the stain instead. Pour the soap-and-peroxide solution onto a clean towel, then firmly dab the stain with the towel.
Don’t add any laundry soap! The fabric should still have some soap-and-peroxide mix in it.
Standard table salt is fine, but any salt will do. You may even be able to use coarse sand and other gritty materials to scrub the stain.
Always rinse from the back side of a stain. Wash it out of the fabric, not through it!
The solvent should ease removal without damaging the material. If you apply detergent immediately, it can harm the material due to its harsh chemical composition.
