Every year in Massachusetts, the unsafe disposal of oily rags and applicators causes fires that damage homes and property.
Safe disposal of oily rags
The oils in some paints, stains, and varnishes release heat as they dry. If oily rags and applicators are left in a pile, a box, or the trash, the heat can remain trapped and cause a fire that quickly spreads to nearby combustibles.
Instead, hang them outside to dry in a safe area or spread them out flat, making sure they are weighted down. They should not be in a pile.
For those who use oily rags daily or weekly: place dry rags in a listed oily waste container to be emptied by a private contractor.
For less frequent users: store dry rags in a small, airtight, non-combustible (such as metal) container with a tight-fitting lid. An old paint can is a good example.
Cover the rags completely with a solution of water and an oil breakdown detergent. Do not add any other combustible material.
Dispose of the container during a household hazardous waste collection event.
