Pianos are pieces of fine furniture, and in this role, they benefit from cleaning and polishing, done carefully to avoid introduction of any fluids into the piano's interior. For many piano finishes, dust is better removed with a feather duster or a vacuum cleaner rather than a cloth, to minimize the abrasive effect of the dust. A piano ...
French polishing a table. French polishing is a wood finishing technique that results in a very high gloss surface, with a deep colour and chatoyancy.French polishing consists of applying many thin coats of shellac dissolved in denatured alcohol using a rubbing pad lubricated with one of a variety of oils.
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). [1]

The color motion gives a clean, bright, shiny surface finish. This is achieved by moving the workpiece with the rotation of the buffing wheel, while using medium to light pressure. When polishing brass (a softer metal) there are often minute marks in the metal caused by impurities.
Aqueous parts cleaning industrial washer. Parts cleaning is a step in various industrial processes, either as preparation for surface finishing or to safeguard delicate components. One such process, electroplating, is particularly sensitive to part cleanliness, as even thin layers of oil can hinder coating adhesion.
Vibratory finishing is a type of mass finishing manufacturing process used to deburr, radius, descale, burnish, clean, and brighten a large number of relatively small workpieces. [ 1 ] In this batch-type operation, specially shaped pellets of media and the workpieces are placed into the tub of a vibratory tumbler.
Changes in temperature can also affect the overall pitch of a piano. In newer pianos the strings gradually stretch and wooden parts compress, causing the piano to go flat, while in older pianos the tuning pins (that hold the strings in tune) can become loose and not hold the piano in tune as well.
