How do I clean these materials off my skin and work areas?
Unless you are using a silicone or alginate expressly made for applying to the skin, you should avoid letting these materials come in contact with the skin while they are in their liquid state.
Remove from the skin as soon as skin contact occurs WHILE THE MATERIAL IS STILL IN IT'S LIQUID STATE.
Using a soft cloth, lightly wipe clean with Isopropyl Alcohol or Mineral Spirits and then wash affected area with soap and water.
Materials that are properly processed and cured are safe for skin contact.
Urethane Rubber. . . Because urethanes are adhesive and will bond to many surfaces, it is recommended to clean up spills while material is still in a liquid or gel state. Once cured, material is very hard to remove.
Silicone Rubber. . . Does not stick to many surfaces. In most cases, you can let silicone rubber cure over many surfaces and then simply remove it. However, silicone can mechanically lock onto porous surfaces (plaster for example). Silicone will also stick to glass. In these cases, it is best to remove rubber while it is still liquid.
What To Use For Clean Up?
General purpose solvents such as Isopropyl Alcohol, Mineral Spirits, and Xylene are usually effective.
They are commonly available at many hardware stores.
* Important: Follow all safety precautions found on container when handling these and other solvents.
