For most folks, removing ink from fabrics is a priority, but occasionally you may want to set ink so it doesn't come out. Whether you've created an elaborate design, or your kids are just signing end-of-year autographs on their friends' T-shirts, start with a fabric marker designed for permanent fabric use. Instructions for setting the ink vary depending on the manufacturer, so always check the package directions.
Things You'll Need
Clean, white cloth
1/2 cup salt
Set the iron on medium high and wait one minute for it to warm up.
Place your fabric on the ironing board with the design face up.
Place a clean, white cotton cloth over it to protect the fabric from scorching.
Iron smoothly over the cotton cloth for 10 seconds, moving the iron in a circular motion so all areas are heated.
Dry the garment in the dryer on a regular cycle.
Wait 24 hours. Pour 1/2 cup of salt into the washer and fill the washer with cold water.
Wash the garment on a regular cold cycle. Don't use detergent. Dry the garment in the dryer.
Always wash the garment in cold water or dry clean. Limit cleaning as much as possible by spot treating.
