Rhubarb contains oxalic acid, which can react with the tarnish on metals like silver, forming soluble complexes that clean the surface. When rubbed with rhubarb, the acid helps to dissolve the tarnish, revealing the shiny metal underneath. This property makes rhubarb a natural cleaning agent for certain metals. However, it's important to rinse the metal afterward to remove any residual acid.
