Rags and Oily Rags
Rags are generally not accepted at rummage sales or through textiles recycling. Use them well, see if your mechanic wants them, or make a quilt. When too far gone, they can go in regular trash. Oily rags from home workshops or art studios present a fire hazard as well as an air pollution hazard. Keep them in a fire-safe, closed container, and bring them to a Household Hazardous Waste Collection Event.
