Paper napkins might disintegrate when you blot, but you can use them if you don’t have a cloth napkin on hand. For a stain from a liquid-based sauce, such as soy sauce, simply skip right to blotting with the cloth napkin.
You can also take the tie straight to the dry cleaner after scraping off the food. Tell them what kind of food caused the stain so they can determine the best way to remove it.
You can also use a hand dryer if you’re out and about.
Only wash your tie when it seems dirty. For example, you might see slight discoloration on the fabric from dirt, or the tie might smell a bit. You shouldn’t wash your tie everyday, as that could ruin the fabric.
