Types of Stains
There can be intentional stains (such as wood stains or paint), indicative stains (such as food coloring or adding a substance to make bacteria visible under a microscope), natural stains (such as rust on iron or a patina on bronze), and accidental stains (like spilling ketchup on your shirt).
Different types of material can be stained by different substances, and stain resistance is an important characteristic in modern textile engineering.
