I was walking outside one shabbos with my tzitzis over my shirt and i noticed that there was a black spot on them im not sure if it was bird droppings or not but if it was and i rubbed soap on the area and rinsed but the stain stayed…can i still daven wearing those tzitzis?
Answer:
Yes, as long as it was washed out and no smell or actual remnants remain, there is no problem of a stain in the garment.
Sources:
See Shulchan Aruch Orach Chaim 79:4-7, that the feces of birds does not have the same stringency as human excrement. Once washed there would be no problem with human excrement and certainly from a bird.
