The Barnet team decided to clean up after themselves following their defeat to Yeovil Town in Tuesday night's Johnstone's Paint Trophy match at Huish Park.
The League Two side were knocked out of the competition following a 1-0 loss.
Instead of rushing home, the players made sure to mop the floor of the away dressing room in order to leave it immaculate.
Yeovil's media team spotted the gesture and wrote on Twitter: "Thank you @BarnetFC who left their dressing room like this tonight. Even mopped the floor. #YTFC "
