According to Wise Bread, as of 2015, the top three fabric softeners are Bounce dryer sheets, Downy Ultra Infusions liquid fabric softener and Seventh Generation fabric softener sheets. Fabric softeners are available in several formats.
Personal preference may come into play when selecting a fabric softener. Fabric softeners can be sheets, liquids or dryer balls. Wise Bread has two additional softeners in its top five list: Seventh Generation Natural fabric softener and Smart Sheep 100% Wool Dryer Balls. Amazon.com confirms these rankings, with two Bounce sheet variations as second and third and the Smart Sheep Dryer Balls topping its list of recommendations based on customer reviews.
