Warning: Rags or paper towels contaminated with vegetable drying oils, particularly those containing iron oxide pigments are susceptible to spontaneous combustion. To prevent unexpected fires, used rags or paper towels contaminated with oil-based materials should be collected in a closeable, air-tight container. Store water-dampened rags or paper towels in a metal container with an air-tight top. Alternately, washing contaminated rags will remove contaminating materials and eliminate risk.
