Should you use hot or cold water to remove stains in cloths?

When removing stains from clothes, it's generally best to use cold water, as hot water can set certain stains, particularly protein-based ones like blood or dairy. Cold water helps to prevent the stain from bonding with the fabric fibers. However, for oil-based stains, warm water can be effective in breaking down the oils. Always check the care label on the garment for specific washing instructions.
