1. Set-in chocolate stains will take a little more work to remove. First, scrape away any dry, solid chocolate left on the garment.
2. Apply a strong stain remover. Shout Advanced Stain Remover has a built-in scrubber brush in the lid that will help work the product into the stained fibers. Let it sit for about five minutes.
3. Wash the stained garment along with a regular load of laundry. Use an enzyme detergent and a scoop of color-safe oxygen bleach, like OxiClean, to help boost stain-fighting power.
