After your treatment, don’t just toss the shirt into a hot dryer. That’s the nuclear option for stain permanence. Air dry the garment first to check if the stain is truly gone. If you see a faint shadow, repeat the process before you machine wash.
Wash the item in cold water with your regular detergent. Add a scoop of oxygen-based bleach (like OxiClean) if the stain is on white fabric. For colors, stick to a gentle cycle. The washing machine is your final ally, not your last resort.
Toothpaste Stain - Easy Ways to Remove Toothpaste From Clothes
