If you mean a white substance covering the leaves it's most likely powdery mildew. This can develop due to a lack of air circulation. Put a fan somewhere near the violets to help circulate the air. You could also change the violet's location if possible to improve its environment.
To kill the powdery mildew already on the leaves you can spray a light mist of Lysol onto the leaves. This won't hurt the plant but it will damage any flowers currently open on the violet. You can also wash the leaves carefully in warm water to remove the powdery mildew.
