Do not use acetone if your garment is made from materials including acetate or triacetate, as the material will be damaged by the application of acetone. If you’re not sure about the composition of the garment, or if you just want to be extra safe, test the product you choose on a very small area that will not be highly visible. For example, use the part of the collar that falls along the nape of the neck and can be covered with long hair, or use the bottom of the shirt if it’s a shirt that is tucked in.
Make sure to blot, not rub; rubbing can spread the stain and make it messier. You’re trying to press the nail polish loose and encourage it to bind to the paper towel to get rid of the excess polish.
Repeat the process of blotting and rinsing until the stain is completely removed from your garment.
If the color doesn’t bleed off when you rub it, you can safely apply the spray to your stain.
Repeat the process of spraying with bug/hair spray, scrubbing with toothbrush, and rinsing in warm water until the stain has been completely removed from your garment. Run the garment through the laundry when you’ve finished.
