If you want to change the color of your nails that you don't like, or if you want to restore the original appearance of your nails, the following methods can easily remove the original nail polish.
Pour hot water into a large bowl. The water should not be too hot to prevent finger burns. Heat the cold water in the microwave oven for one minute.
When selecting a small bowl, make sure the bowl is large enough to hold five fingers inside.
Soak the tissue in 100% pure acetone and let it wet. Then wet your nails with a paper towel containing acetone.
Place the nail in acetone to ensure that the acetone is absorbed. To smell acetone, cover your hands and bowl with a towel.
After about 10-15 minutes, take your hand out of the bowl and wipe it with a paper towel. If it is not thorough, you can use a nail file to clean it.
You can also cover the cotton ball soaked with acetone on the nail, then wrap it with metal foil, wait 10-15 minutes, remove the metal foil and cotton ball, and clean the nail.
