A glossy bolster patch can be residue, wear or a changed outer finish. Establish a clean baseline before deciding what protection can achieve.

Assess the starting condition

Inspect the dry patch and ask about previous cleaners, dressings and rubbing. Compare a nearby section with similar use rather than a rarely touched area.

A practical working method

  1. Trial the approved cleaning routine locally.
  2. Remove residue and allow appropriate drying.
  3. Assess whether the appearance changes after cleaning.
  4. Refer persistent finish change before coating renewal.

Common mistake

Scrubbing until the patch looks matte can remove or alter the original finish. A coating is not a restoration product for every worn or glossy area.

What a useful result looks like

The useful result distinguishes removable contamination from retained wear. Keep photographs and the cleaning history so a specialist can assess the actual finish rather than a surface hidden beneath fresh dressing.
