What Is Metal Polish?
Metal polish is a liquid or paste containing an abrasive.
Metal polish can be used to remove oxide film, dirt, and other contaminants from metal by dropping it on the metal and then wiping it off with a cloth. Since all one has to do is simply drop it on the metal and wipe it up, it is relatively easy for anyone to use.
Metal polish contains various types of abrasives and their particles, so it is necessary to select the appropriate one depending on the type of metal and its finish.
Uses of Metal Polish
As the name suggests, metal polish is used to polish metal.
For example, stainless steel sinks start out polished, but as they are used, they lose their shine and water repellence due to water stains and fine scratches caused by rubbing against dishes. By removing these scratches and stains with Metal Polish, the surface can be made clean, and water repellence can be restored.
Principle of Metal Polish
Metal polish contains abrasive materials. When polishing metal and other materials, one often thinks of a whetstone, but what is contained in a Metal polish is more like a dispersed mixture of unconsolidated whetstone material.
Types of Metal Polish
The following three types are generally used:
1. Silicon Carbide
Silicon carbide, also known as carborundum, is the second hardest material after diamond, which is the hardest of the materials, and can be used for a wide range of hard metals such as knives and soft metals such as copper.
2. Black Silicon Carbide
Black silicon carbide is not as hard as green silicon carbide, it is more durable, making it suitable for polishing soft metals.
3. White Alundum
White alundum is a white high-purity alumina abrasive and the lowest hardness material of the three. It is suitable for polishing not only metals but also glass and crystal.
