I had been using a wash like Fit Organic fruit spray on mine. I do not know exactly how many lbs or bushels of fruit you are talking about or how long you are storing it for.
Also try putting either boxes of baking soda ( the type with the mesh sides) or some of those odor absorbing packages in there as well.
I have been trying to figure out how to store my apples as well when they get bigger. I have checked with some companies about freezers and they get too low to use for storing fruit, unless want to cut and freeze the fruit. I will have too many trees to do that with.
