Choosing the Right Water Temperature at a Laundromat

One of the most important cycle choices you’ll make at a laundromat is water temperature. Get it right, and your clothes come out clean without shrinking or fading. Get it wrong, and you might find your favourite wool jumper has become a doll’s cardigan. Here’s a practical guide to water temperature selection at Love Wash.

Cold Water (Around 20–30°C)

Cold water is the right choice for the majority of everyday laundry. Modern detergents are formulated to work effectively in cold water, making it possible to achieve an excellent clean without heat. Use cold water for:

• Coloured and dark clothing (prevents fading)
• Lightweight fabrics — cotton t-shirts, casual shirts, underwear
• Lightly soiled items
• Anything that might shrink in warm or hot water
• Synthetic fabrics like polyester and nylon
• Workout gear and activewear

Cold washes are also more energy-efficient and gentler on fabric fibres, extending the life of your clothing.

Warm Water (Around 40°C)

A warm wash is appropriate for moderately soiled items where cold water might not fully lift stains and odours. Use warm water for:

• Work clothes that are mildly soiled
• Household items like dish towels and hand towels
• Moderately stained items where hot water would be too harsh
• Synthetic fabric blends
• Jeans and heavier casual wear

Check care labels — many garments have a 40°C maximum wash temperature, which maps to a warm wash. If the label shows a tub with one dot, that’s 30°C; two dots is 40°C.

Hot Water (60°C+)

Hot water is reserved for situations where hygiene and sanitisation are priorities, or where heavy soiling needs maximum cleaning power. Use hot water for:

• White cotton items — sheets, pillowcases, white towels
• Heavily soiled items — work uniforms, kids’ sports gear, nappies
• Items from someone who has been unwell
• Kitchen cloths, cleaning rags, and highly used towels
• Bedding that needs dust mite elimination

Be cautious with hot washes — they cause more fabric shrinkage and colour fading than cold or warm washes. Only use hot for items that specifically need it and that you know are heat-safe.

What Love Wash Machines Offer

Our machines at St Marys, Bella Vista, Waterloo, and Zetland offer cold, warm, and hot cycle options with clear labelling. If you’re unsure which to choose for a specific item, our staff are happy to advise.

The Bottom Line

When in doubt, default to cold. It’s effective for most laundry, gentler on fabrics, more sustainable, and reduces the risk of shrinkage or colour running. Reserve warm and hot cycles for the items that specifically benefit from them.
