Abstract
Abstract The present disclosure is directed to an oil mop for use by an individual person for removing oil from the top of an oil-water mixture and is directed to the use of narrow thin gauge strips of a petrophilic, aerophobic, hydrophobic material such as fibrillated polypropylene which when dipped into oil and water sops up the oil and leaves the water. A mop so constructed is attached to a handle and may be passed over the oil covered surface similar to mopping a floor and the oil wrung out into any container.
