24 Cold Water Wash Tips to Save Cash

Hot water washing costs money every single time you run a load. Your water heater burns energy to heat water that ultimately just rinses dirt out of your clothes, and about 90% of a washing machine’s energy goes toward heating that water.

Switching to cold water can cut your laundry energy costs by more than half while modern detergents clean just as well without the heat. The myth that clothes need hot water to get clean is outdated, but making the switch effectively requires knowing a few tricks.

Here are 24 cold water wash tips to save cash.

Use cold water detergent formulas

Regular detergents work in cold water, but formulas specifically designed for cold water perform better. These detergents activate at lower temperatures and contain enzymes that work without heat.

Brands like Tide Coldwater or similar products cost about the same as regular versions.

Pre-treat stains before washing

Cold water doesn’t break down tough stains as easily as hot water. Treating stains with a pre-wash spray or stick before tossing items in the machine gives the detergent a head start.

This takes 30 seconds per item and dramatically improves results.

Add stain remover to particularly dirty loads

For heavily soiled laundry, adding oxygen-based stain remover boosts cold water cleaning power. Products like OxiClean dissolve in cold water and tackle stains that might otherwise need hot water.

Use according to package directions.

Don’t overload the washer

Cold water needs more agitation time to clean effectively. Cramming too many items into one load prevents proper cleaning action.

Leave room for clothes to move freely and you’ll get better results.

Use the full recommended amount of detergent

Cutting back on detergent to save money backfires in cold water. Use the amount specified on the package for cold water washing.

Underdosing leaves clothes dingy because there isn’t enough cleaning agent.

Increase rinse time if your machine allows

Some washers let you extend the rinse cycle. An extra rinse ensures all detergent gets removed in cold water.

Residual detergent can make clothes feel stiff or look dull.

Sort lights and darks more carefully

Cold water doesn’t set dye as well as hot water. Washing new dark items separately prevents color transfer to lighter clothes.

After a few washes, most items are safe to mix.

Wash whites separately with brightening agents

White clothes washed exclusively in cold water may yellow over time. Washing whites together and adding a whitening agent or bluing helps maintain brightness.

Occasional hot water washes for whites can help too.

Choose longer wash cycles

Many machines offer quick wash options, but longer cycles give cold water more time to work. The extended agitation compensates for lower temperature.

Quick washes work better with warm or hot water.

Shake out clothes before washing

Dirt and debris that fall off before washing require less cleaning action. Shaking items outside or over a trash can removes loose particles.

This simple step helps cold water washing work more efficiently.

Turn heavily soiled items inside out

Grass stains, dirt, and sweat concentrate on the outside of clothes. Turning items inside out exposes these areas to more direct washing action.

This helps cold water penetrate and clean better.

Use mesh bags for delicates

Cold water is gentler on fabrics, which is great for delicates. Mesh laundry bags prevent tangling and protect delicate items during the wash cycle.

Your delicates last longer and come out cleaner.

Add white vinegar to the rinse cycle

A half cup of white vinegar in the rinse helps remove detergent residue and softens clothes naturally. Vinegar works well in cold water and costs much less than commercial fabric softeners.

The smell disappears when clothes dry.

Avoid fabric softener in every load

Fabric softener builds up on clothes over time, especially in cold water. Use it sparingly or skip it entirely and use vinegar instead.

Buildup makes clothes less absorbent and can trap odors.

Check water temperature actually is cold

Some washing machines’ cold setting still mixes in warm water. Run the cold water faucet nearby for a minute and feel the actual temperature.

If your ‘cold’ wash feels warm, your machine might need adjustment.

Use shorter spin cycles for gentler cleaning

High-speed spinning can set wrinkles in cold water washing. Using a slower spin speed results in slightly damper clothes but reduces wrinkles.

The energy saved by using cold water more than makes up for slightly longer drying.

Treat athletic wear with sports detergent

Workout clothes with technical fabrics often hold odors. Sports-specific detergents work in cold water and contain enzymes that break down sweat and bacteria.

Regular detergent sometimes leaves performance fabrics smelling musty.

Pre-soak heavily soiled items

Items with ground-in dirt benefit from pre-soaking in cold water with detergent for 30 minutes before washing. This loosens dirt so the wash cycle can remove it.

Pre-soaking works especially well for kids’ play clothes.

Wash jeans inside out in cold water

Hot water causes denim to fade and shrink. Washing jeans inside out in cold water preserves color and fit while still getting them clean.

This also reduces wear on the fabric.

Use baking soda to boost cleaning power

Adding half a cup of baking soda to the wash helps remove odors and boosts detergent effectiveness in cold water. Baking soda is cheap and works well with any detergent.

It’s especially good for musty-smelling towels.

Wash towels and sheets separately

Towels and bedding create large, heavy loads that need more cleaning action. Washing them separately in smaller batches ensures cold water can clean them thoroughly.

Mixing them with lighter items prevents everything from getting clean.

Clean your washing machine monthly

Residue builds up faster in cold water washing. Run an empty cycle with hot water and washing machine cleaner monthly to prevent buildup.

A clean machine washes clothes more effectively in cold water.

Adjust for water hardness

Hard water makes cold water washing less effective. If you have hard water, use more detergent or add a water softening agent.

Some detergents include water softeners specifically for this issue.

Don’t let wet clothes sit

Removing clothes promptly after washing prevents mildew, which is more likely to develop in cold water conditions. Transfer clothes to the dryer or hang them immediately after the cycle ends.

Where savings meet simplicity

Switching to cold water washing saves the average household $60-150 annually just on water heating costs. The savings increase if you dry clothes on racks instead of using the dryer.

Modern cold water detergents have eliminated the performance gap that used to exist between hot and cold washing. Your clothes will last longer thanks to gentler treatment, colors will stay brighter, and you’ll reduce your environmental impact while keeping more money in your pocket.

The adjustment takes one load to get used to, and after that it becomes the new normal that happens to cost less.
