How do you kill poison ivy on bedding?

To kill poison ivy on bedding, first, carefully remove any contaminated bedding and wash it in hot water with detergent to remove the oils that cause skin irritation. For persistent stains or oils, consider using a diluted solution of bleach or vinegar, but test a small area first to ensure it won't damage the fabric. After treatment, launder the bedding again to ensure all residues are eliminated. Always wear gloves when handling poison ivy and contaminated items to prevent skin exposure.
