Looking to reduce your environmental impact without overhauling your routine? One of the simplest and most effective changes you can make is switching to cold water for your laundry. Compared to washing with hot or warm water, using cold water offers considerable benefits for the planet, your clothes, and even your energy bills. Here’s how:
Better for the Environment
Traditional hot water cycles consume a great deal of energy—most of it simply to heat the water. By switching to cold (or even just warm) water, you can dramatically reduce your household energy use and lower greenhouse gas emissions.
There’s also a lesser-known advantage: washing with cold water significantly reduces the amount of microfibre pollution that enters our waterways. Synthetic fabrics shed more microfibres when exposed to hot water, which then flow into the water supply. Cold water is gentler on fabrics, meaning fewer fibres break loose with each wash.
More Cost-Effective
Washing in cold water can noticeably cut down your electricity bills. With energy costs on the rise, it’s a practical way to reduce household expenses—no need to heat up litres of water every cycle.
Cold water is also gentler on clothing, helping to preserve fabrics, colours and fit. By reducing heat-related damage and excessive agitation, your clothes stay in better shape for longer—saving you money by extending the life of your wardrobe.
How to Wash Effectively in Cold Water
A few simple practices can ensure your cold water washes are as effective as possible:
-
Select the correct cycle: Use the cold or ‘tap cold’ setting on your washing machine. Some models even have dedicated cold wash modes.
-
Use a detergent formulated for cold water: Detergents like Blueland Laundry Detergent Tablets contain enzymes such as amylase and mannanase, designed to break down stains effectively in cooler temperatures.
-
Avoid overloading: Give your laundry enough room to move, so detergent and water can circulate and rinse clothes thoroughly.
Choosing the Right Detergent
A detergent specifically formulated for cold washes is crucial. Blueland’s Laundry Detergent Tablets, for example, use eco-friendly, enzyme-powered formulas that tackle everything from food and grease to protein-based stains—all without needing hot water.
Should You Pre-Treat Stains?
Absolutely. Pre-treating stains can significantly improve cold water washing results. Here’s how:
-
Identify the stain type: Is it oil-based (e.g. salad dressing), protein-based (e.g. blood or sweat), or a mix?
-
Remove excess residue: Gently blot or scrape with a cloth or paper towel—being careful not to spread the stain.
-
For oil-based stains: Rub in a small amount of liquid dish soap with water, gently working the area.
-
For other stains: Use a targeted stain remover—we recommend Blueland Oxi Laundry Booster.
-
Let it sit: Allow the product time to break down the stain.
-
Wash as usual: After pre-treatment, run your standard cold wash. If the stain remains, repeat the process.
Frequently Asked Questions
Can I Wash All Clothes in Cold Water?
Yes, nearly all fabrics can be washed in cold water. In fact, delicate materials like silk and lace require cold water to avoid damage, while everyday fabrics such as cotton and wool benefit from the reduced agitation and heat exposure.
Does Cold Water Save Energy?
Yes—dramatically so. Heating water makes up a large percentage of energy use in laundry. By washing in cold water, you can cut energy use by up to 90%, saving money and lowering your carbon footprint.
Will Cold Water Shrink Clothes?
No. Shrinkage typically occurs due to high heat. Cold water helps maintain fabric size and shape. Still, always check garment care labels to ensure you’re following the correct instructions.
A Simple Switch, a Big Difference
Washing with cold water is a small change with a powerful impact. It saves energy, lowers costs, reduces pollution, and extends the life of your clothes—all without sacrificing cleanliness. With the right detergent and a few easy adjustments, your laundry routine can be both sustainable and effective.
