Thank you for taking the time to write this! I used soap, lukewarm water, and also baking soda and vinegar, but without success. The fiber in the burlap really soaked up the poo (my dog was sick and had diarrhea), so it’s a tough one to clean. I’ll look into the bile soap and enzyme-cleaner, hopefully that’ll do (even though it dried up now). I bet it will, considered you’ve probably dealt with more tenacious stains, haha :-). Appreciate the help!
