Will paintballs stain?
No! But yes! Maybe! Paintballs are designed and manufactured to be environmentally friendly, hypoallergenic, water-soluble and biodegradable. this includes the shell of the paintballs and paint fill itself. If washed soon after a day of play, paintball splats will wash completely out of clothing. However, in rare occasions, paintballs may stain lighter colored clothing if the paint is left on the clothing worn to play in for more than a few days. Best bet is to put clothing hit with paintballs in the wash when you get home from a day of play to ensure that the fill won’t set into lighter colored fabrics and leave a light mark.
