A seal cleaning device for seals located at the interface of the inner and outer tubes (14, 30) of a telescopically acting unit, such as a telescopically acting suspension; characterised, in that said device comprises a collar and a first flexible cleaning projection; wherein said cleaning projection is adapted for insertion between a said seal and an outer surface of a said inner tube; wherein said first flexible cleaning projection extends to a pointed hook-shaped tip; said tip formed of material sufficiently thin and with a sharp upper edge to enable insertion of said tip between said inner tube and a lower lip of an oil seal disposed around said inner tube; wherein said hook-shaped tip is adapted to dislodge detritus from between the inner circumference of said oil seal and said inner tube; said hook-shaped tip including a tapered shoulder guiding dislodged detritus away from said oil seal; wherein said collar is flexible, partly open, formed as a single piece of plastic, and encircles a portion of said inner tube when in use; said portion being greater than 180 degrees of the circumference of said inner tube; the opening of said partly open, flexible collar being sufficient to allow said collar to be fitted into a partially encircling position around said inner tube by pressure applied to said collar normal to the axis of said inner tube; and wherein said first flexible cleaning projection is integrally formed on said collar; said first flexible cleaning projection projecting upwardly from a section of an upper rim of said partly open, flexible collar; said first flexible cleaning projection is inwardly biased to fit closely against said outer surface of said inner tube when said partly open, flexible collar is in said partially encircling position around said inner tube for use. characterised, in that said device comprises a collar and a first flexible cleaning projection; wherein said cleaning projection is adapted for insertion between a said seal and an outer surface of a said inner tube; wherein said first flexible cleaning projection extends to a pointed hook-shaped tip; said tip formed of material sufficiently thin and with a sharp upper edge to enable insertion of said tip between said inner tube and a lower lip of an oil seal disposed around said inner tube; wherein said hook-shaped tip is adapted to dislodge detritus from between the inner circumference of said oil seal and said inner tube; said hook-shaped tip including a tapered shoulder guiding dislodged detritus away from said oil seal; wherein said collar is flexible, partly open, formed as a single piece of plastic, and encircles a portion of said inner tube when in use; said portion being greater than 180 degrees of the circumference of said inner tube; the opening of said partly open, flexible collar being sufficient to allow said collar to be fitted into a partially encircling position around said inner tube by pressure applied to said collar normal to the axis of said inner tube; and wherein said first flexible cleaning projection is integrally formed on said collar; said first flexible cleaning projection projecting upwardly from a section of an upper rim of said partly open, flexible collar; said first flexible cleaning projection is inwardly biased to fit closely against said outer surface of said inner tube when said partly open, flexible collar is in said partially encircling position around said inner tube for use.
