.Bourne Fire/Rescue & Emergency Services and mutual aid recently battled a four-alarm fire that started with oily rags. The oils in some paints, stains, and varnishes release heat as they dry, and that heat can cause ignition if applicators are left in a pile, a box, or a trash bag. Instead, dry them individually outdoors and dispose of them safely, either in an old can with water and detergent or a listed container emptied by a contractor: https://www.mass.gov/info-details/disposing-of-oily-rag
