DIY Mold Release Agent
- 1). Pour cooking oil into a spray bottle. Use a funnel to avoid spilling excess oil. Wash the oil off the funnel with soap and hot water.
- 2). Do not add more cooking oil than you will use within the next few months. Once the bottle has been opened, cooking oil will turn rancid within approximately six months. You can extend the shelf life of your oil by storing it in the refrigerator.
- 3). Add a few drops of clove oil to the vegetable oil. This will help to inhibit mold and mildew from forming on your casting mold. Some moisture-containing casting materials like plaster and alginate have a tendency to develop mold.
