Abstract: An electrical connector cleaning devices includes a first elongate cleaning element extending outwardly from a housing, wherein the first cleaning element includes raised surface portions extending radially outward from its outside wall surface. A second elongate cleaning element extends outwardly from the housing and includes raised surface portions extending radially inward from its inside wall surface. Each of the first and second cleaning elements is a cylindrical tube having a longitudinally extending open seam forming a gap for permitting a flexing of the cleaning element walls through a biasing force placed thereon. Each of the raised surface portions forms rings extending around the inside and outside wall surfaces of the first and second cleaning elements, respectively. One ring has its raised surface portions angularly offset along the longitudinal direction from an adjacent raised surface portion in an adjacent ring of raised surface portions.
