Chalkbrood will go away on its own.  The cause is chilled brood.  If you use the banana it will go away.  If you don't use the banana it will go away.  If you pour apple cider vinegar on it, it will go away.  If you don't it will go away... though the vinegar may actually help some.  The acid will kill the chalkbrood spores which can only germinate at between 6.0 and 7.0 ph...

"As chalkbrood is aggravated by chilling, practices that lead to loss of heat in infected hives (e.g. removing adult bees, or giving them extra brood to rear) should be avoided."
