Many food or beverage stains, such as chocolate, jam, baby food, beer, and dairy are more easily removed with cold water soaks and washes. Cold water is also recommended for urine and blood stains. Other stains, especially oily or greasy ones, do better in warm or hot water.
Hot water removes stains by breaking down and dissolving the stain-causing substances. Cold water has a different mechanism – it prevents the binding between proteins from the stain and the fabric, making it better for protein-based stains like baby food or blood.
Protein stains such as dairy, blood, egg, glue, and white deodorant marks should always be washed in cold water. Hot water can actually cook the protein, causing it to absorb into the clothing fibres, and making it almost impossible to remove.
Why Does Hot or Cold Water Matter for Stain Removal? Hot water can set some stains into fabric but can dissolve others depending on the composition of the stain. One example of a stain that requires cold water is a blood stain.
Running cold water over fresh blood stains should get rid of the majority of them. Don't use warm or hot water because it will cause the stain to set. You can use hydrogen peroxide to get rid of the rest of the stain too.
Soak the garment in a solution of liquid detergent and cold water, like Tide Ultra Stain Release Liquid. Allow the garment to soak for up to 5 minutes, weighting the item with a white towel to keep it totally submerged.
Using hot water to wash clothes is suitable for certain fabrics and stains, as it can help to remove dirt, grease, and oils more effectively. However, hot water can also cause shrinkage and fading in delicate fabrics, so it's essential to check the care label on clothing items before washing with hot water.
Many types of stains can be easily removed with cold water. Using hot water can potentially “bake in” stains by causing molecules to coagulate and bond with the fibers of the fabric. However, you may need to pretreat oily stains with warm water to dissolve the oil molecules before throwing them into the wash.
When water is heated, its molecules move faster due to the high level of kinetic energy in them. Higher kinetic energy makes hot water an effective solvent. The higher the kinetic energy in molecules, the faster they will agitate the surfactants. This makes the stains come off much easily.
The heavy-duty or stain removal cycle works best for tough stains. If your washer has a pre-wash or steam function, use it for added cleaning power. Hot water settings are ideal for greasy stains, while cold water helps with protein-based stains. For delicate fabrics, stick to a gentle cycle to avoid damage.
But in the case of poop stains, cold water proves more beneficial. It helps prevent the stain from setting into the fabric, creating a solid bond. Aim the water on the reverse side of the stain to push it out of the fabric rather than through it.
Some of the toughest food stains to remove include coffee, tea, gum, peanut butter, mustard, berry juice, tomato-based sauces, baby food, red wine, chocolate, cooking grease and butter. For coffee or tea stains, rinsing in hot water or treating with dishwashing liquid can be effective.

Advantages of mopping with hot water
Hot water is great for removing grease, stubborn dirt and caked-on residue. It is more effective in killing bacteria and germs. Hot water is a good choice for tile floors and vinyl. Be sure to check the manufacturer's instructions to make sure your floor is resistant to hot water.
Cold water is fine for most clothes and other items that you can safely put in the washing machine. It can remove many stains from clothing, including grass on your kid's jeans or makeup smudges on a sweater.
