How to Remove Heat-Sealed Patches on Clothing

by Laure Justice

Heat-sealed patches have been a popular sew-free garment addition for years. Their uses range from the most practical repairs to name tags to stylish embellishments. Heat-sealed patches have been used as an easy way to fix torn knees in pants and for decorating clothing. Sometimes, however, the patches need to be removed, and they leave a residue behind that is similar to plastic. Heat-sealed patches can be thoroughly removed from clothing with a little bit of heat and some cleaning solutions.

Items you will need

  • Steam iron
  • Ironing board
  • Scraper with smooth edges
  • WD-40
  • Dish soap
Step 1

Use the steam iron and ironing board to heat and moisten the patch and the area of the garment around the patch. If you need to reheat the patch while working, put a scrap of fabric on the ironing board and place the garment right side down and press quickly with the steam iron.

Step 2

Use the smooth-edged scraper to scrape the patch and the residue off of the garment. You should be able to get most of the residue, but probably will not get all of it in this step.

Step 3

Use the WD-40. Spray it directly on the residue and use the scraper to work the rest of the residue off of the garment.

Step 4

Apply the dish soap after removing the patch to cut the greasiness of the WD-40. Follow by immediately laundering the garment to completely remove the WD-40. According to the Natural Handyman website, WD-40 can leave a yellowish-brown stain on fabric if not laundered.


  • The WD-40 might stain or otherwise damage delicate fabrics, so test for colorfastness on a section that will not show.
