When the cotton cover of a fire hose becomes oily or greasy, it should be washed with a solution of mild soapy freshwater and __________.

Correct Answer: Option B — a soft-bristled brush

Maintaining fire hose integrity requires gentle cleaning to avoid damaging the outer jacket. A mild soap solution and a soft-bristled brush effectively remove grease and oil without compromising the fibers. Harsh chemicals or wire brushes can abrade the fabric, significantly reducing the hose's burst pressure rating and overall service life.
