Hand me down co sleeper

Breanna • Mon, Jan 29 • Joy’s Mommy

My bestie has gifted me her co sleeper that she used for her 4 kiddos over the course of 7 years. It hasn’t been used in about a year. I unpacked it and set it up last night and it is kind of musty smelling. Is there anything I can do to it to freshen it up besides air it out???
