When to use a cooler water temperature to remove stains

Most stains can be washed in hot water, and it’s the best option for many types of fabric. There are, however, a number of instances where hot water could actually make stain removal more difficult by setting the stains, or damaging your clothing. In these cases, the decision to use hot or cold water to get stains out sides with the cooler temperature. ‘Cold’ water is considered to be about 30°C. It’s recommended that you don’t set your washing machine temperature any lower than this, as colder water can affect the efficacy of your detergent.

Frequently asked questions about using hot or cold water to remove stains

Does hot water remove stains in delicate clothing or should I use cold water?

Regardless of the type of stain you’re dealing with, some delicate materials should always be washed in cold water, not hot. To avoid problems such as wrinkling or shrinking, use a cold wash for woolly jumpers, silk lingerie, satin skirts, over-dyed jeans and tie-dyed clothing.

Is hot or cold water better for stains that are protein based?

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. Cold water helps lift the stain without setting it.

Does cold water set stains, or can I use it for removing all types of stain?

Using cold water can help to conserve energy and cut down energy bills in the long term. Plus, good-quality detergents are specially designed to wash effectively at lower temperatures. However, some stains will require a higher temperature to get them out completely, and clothing such as underwear and baby clothes should be washed at a higher temperature for proper sanitisation.

Should I use hot or cold water to remove stains if I don't know what made the stain?

If you’ve found mystery marks on your clothing, always try going down the cold-water route first as you don’t want to risk setting the stain into the fabric. In many instances, this should be sufficient to lift the stain, and you can then wash in hotter water if you want a more thorough clean. If the stain doesn’t come out in cold water, move on to hotter water and you should see results.
