Vintage textile items with decorated metal threads represent a special sort of overwhelming treasure of cultural collections that is why a distinctive concern is highly needed to keep them well-protected in museums and private collections. Cleaning corroded metal threads was dealt with by either mechanical or chemical means; with limited success.Clinical Ultrasound scaler represented an appropriate solution that aid scaling of minute corrosion layers on gilded metal threads with a great controllability in-situ (museum). A stored vintage decorated fabric dated to 17-18th century A.D, was selected for being cleaned. Cleaning with Piezoelectric ultrasound waves with localised vibrational mechanical actions was successfully carried out at a power range to be approximately 7.25-9.37 watts. Portable microscope aided monitoring the scaling process at the worktable stage, with no harm to the accompanying materials.The rapidity and accessibility of cleaning not to be comparable by other method, with the controllability all at once.
