Our microcell expanding sponge is optimized to be used on bikes with a soft and rough side. Clean your frame and components easily with the soft side of the sponge. The non-soft side is not suitable to use on your frame. This side can be used to remove tough dirt on metal components or to clean your chain.
Note: The sponge is vacuum packed to save space and packaging. After opening it, your sponge will expand to its true size.
