An air freshening device is provided for detecting water leaks and protecting surfaces from water damage due to leaks. The device includes: a tray, configured for being placed upon a surface located under a water pipe; a removable and replaceable liner placed upon the tray, the liner comprising a material configured for releasing an air freshening substance into air, and for increasing the release rate of the substance upon contact with water. The increase of the release rate of the substance leads to an intensifying of the scent of the substance in air, and indicates the presence of a leak from the water pipe. The tray prevents water leaking from the water pipe from touching the surface.
