How can I get spider poop out of cotton fabric?
You have to treat them like you would an allergen. Because of the size of the droppings, they can be kind of hard to get it out, so it may be necessary to repeat wash in hot water more than once. Any good detergent should do. Here’s a quick article on the effectiveness of getting allergens out of cotton: May 21, 2007 — Hotter is better when it comes to killing dust mites and other allergens in your laundry. A new study shows washing laundry in hot water (140 degrees Fahrenheit) kills 100% of dust mites. But turn the dial down just 36 degrees to a warm, 104 degree Fahrenheit wash and only 6.5% of dust mites are killed in the laundry. Hotter water was also better at removing dog dander and pollen. But if your delicate laundry can’t take the heat, researchers also suggest another way to reduce dust mites and allergens in the laundry: wash at a lower temperature (between 86-104 degrees Fahrenheit) and then rinse the laundry twice with cold water for at least three minutes each.

I don’t recall that I’ve ever seen spider poop, but if I HAD I know I’d use hydrogen peroxide to get it out of cotton fabric. I’ve learned to use this in place of bleach or any other spot, fungus or other type of cleaning agent in my laundry. It works absolutely beautifully. Please try it. Put one full cup in your washload (along with your normal amount of laundry soap), and see how it works. Get rid of the spider poop! (P.S. I get scratched by my cat occasionally and have had the darndest time getting blood out of my blouses or jeans. Hydrogen peroxide put on the blood stain right before I toss it in the wash is the best thing I’ve ever seen. NO blood stains any more! It’s so great.) Good luck!
