To keep your Viking cue in top condition, regularly clean the shaft with a damp, soft cloth to remove chalk and dirt, and occasionally use a cue shaft cleaner for deeper cleaning. Store your cue in a dry, cool place, ideally in a cue case, to protect it from warping or damage. Handle your cue with care, avoiding excessive pressure or dropping, and periodically check for any signs of wear or loose parts. Address issues promptly to preserve its performance and longevity.
