The invention relates to a crosslinking pipeline cleaner, belonging to the field of cable application. The crosslinking pipeline cleaner comprises a cable drawn wire, a Harvard module and a stainless steel wire brush, wherein the main body of the Harvard module is cylindrical, the interior therof is hollow, and the two ends thereof are tapered; the cable drawn wire passes through the Harvard module, and the cable drawn wire and the Harvard module are mutually fixed; and the stainless steel wire brush is wound and fixed on the outer side of the Harvard module to surround the Harvard module. The invention has the advantages of reasonable structural design, convenient operation and strong practicality, is economical, saves a great quantity of water resource, is environmental-friendly, saves production time, and does not need to carry out air drying on moisture in the crosslinking pipeline, thus greatly improving the production efficiency, preventing a crosslinking cable from contacting with hydrone, and ensuring the cable quality.
