Why do all Metal pieces get the polished before the experiment

1.	Why do all Metal pieces get the polished before the experiment
Answer» Most of the METALS get oxidied when exposed to oxygen and HUMIDITY, which required the removal of oxidized materials from the metal surface, and the process is called polishing. Moreover, polishing is often USED to ENHANCE the appearance of an item, prevent contamination of instruments, remove and BLOCK further unwanted oxidation, create a reflective surface and prevent further corrosion.
