How to Remove Set-In Mud Stains
If the mud stains are quite old, there is another trick to help you remove them. Follow the above steps, but instead of liquid detergent, apply hand sanitizer to the stain. Just test this method on a small, inconspicuous area of the garment first to ensure that it will not damage the fabric. Using a clean brush, work the sanitizer gel into the fabric and let it saturate the stained area for an hour. Wash as normal. You may need to repeat the hand sanitizer step again to ensure the stain is fully removed.
Removing Mud Stains from Delicate or Dry-Clean Only Fabrics
If the garment is labelled delicate, dry-clean, or made from a fabric like silk or wool, you should take it to a professional cleaner to handle the stain. Trying to remove a mud stain with the previous steps may permanently damage a delicate or dry-clean only piece of clothing. So play it safe, and leave these garments to the professionals.
With these tips, removing mud stains should be simple and straightforward. Even the worst stains from a wet football pitch or muddy day of hill walking can come off with enough time, patience, and a little know-how.
