Here’s how he treated our stains:
Grass stain: Wet fabric, rub in laundry detergent, let sit for 10-15 minutes, rinse with warm water while vigorously scrubbing. It took us a couple of tries and a bit of bleach, but the green disappeared.
Ketchup: Wet, rub in laundry detergent, soak in cool water, air dry.
Juice: Blot, scrub with soap, Soak, then add bleach as necessary. Blue is the toughest color to remove.
Pen ink: A very hard stain that likely will require dry cleaning solution. Still, try to wet stain immediately. Some soaking, scrubbing, and bleaching may help fade the ink.
