What you need:
1 tsp. Milk
1 tsp. Knox Gelatin (unflavored)
1. Add the milk and gelatin to a small, microwave-safe bowl. Stir the mixture to blend it a bit (it will be kind of chunky).
2. Microwave for 10 seconds, it will have a goo look.
3. Apply with a makeup brush (not afraid of losing) and let dry for at least 10 minutes.
4. Peel and see what dirt was removed.
