What should you do with a rag that has been used to wipe up spilled gasoline?

Explanation:

A gasoline wiped rag soaks gasoline in it and it cleans the area that is spilled with gasoline. Thus the soak rag contains gasoline and is now dangerous because it is flammable and can easily catch fire. Therefore, after wiping out the gasoline with the rag we should hang it in the open air to dry up for sometime. After the rag is completely dried up, we can keep it the place where used rags are kept or can clean it by washing and now it is safe for reuse.
