Here at Vapor Fresh , we strive for the best. Between the energy savings, carbon footprint reduction and lengthening the life of your favorite workout apparel, being able to provide a complete clean in cold water isn't just a secondary thought for our laundry detergents - it's the primary goal. In general, the hotter the water temperature the cleaner your clothes will be. However that does not mean you want to always use the hottest setting possible.
In fact the opposite is true-- you should use the lowest temperature possible that will allow you to clean your laundry properly. First, hot water comes with risks. It accelerates fabric deterioration, increases chances of clothes shrinking and allows colors to run and fade. Obviously these are all things you want to avoid. If you can get away with using cold water washes by using a cold-water detergent , you stand to save a lot of money. In most situations, a hot water wash is not only overkill when it comes to water temperature, but it is not even the ideal option due to its risks and high operating costs.
An estimated 75 to 90 percent of all the energy your washer uses goes to warming up the water, so switching to colder water can lower your gas or electric bill. Cold water can also reduce wrinkles, which saves energy costs and time associated with ironing. Sometimes, though, warm or hot water works better based on the fabric or the need.
Take fabric: Knits and synthetic fabrics such as spandex, nylon, polyester, and rayon blends are easier to wash in warm water. If sanitizing is the goal—say you or someone in your family is sick—washing clothing and bedding in hot water can help stop the spread of germs. Climate can pay a role, too. In these areas, warm or hot water may be necessary to get clothes clean. Want to save money while helping the environment? Cold-water washing may be the best choice—but check the label and the stain first.
GE Appliances has engineered a front load washer that stays fresh with Microban in the gaskets and an OdorBlock venting system. Stains happen. Hot water will remove water soluble stains like tomato sauce, wine, and blood more quickly. The faster the water molecules are moving, the greater the chance they will blast themselves into the fabric to loosen and remove dirt, grease, and stains. A lot of the energy used to wash a load of laundry is funneled directly into heating the water—the latest studies suggest up to a third of the energy needed to wash a load goes into producing the heat.
Consider how much laundry you do per week, and then think about how it will spike your power bill and affect the environment! Hot water can cause bright colors to run and fade, and can shrink certain types of fabric.
Hot water can also damage certain synthetic fabrics like polyester, nylon, and vinyl. The heat breaks down the fibers and can ruin the fabric. Hot water can set stains on delicate fabrics and can cause them to shrink, fade, and permanently wrinkle. These fabrics are sensitive to temperature and cleaning solutions, so use a detergent made for delicates. You can wash whites in hot or cold water. Should you use hot or cold water to remove stains? While hot water can often kill more bacteria, cold water is often best to get out stains.
Not only do you have to know whether to use hot or cold water for stains, you have to consider the color of the fabric and type of stain. For stains on whites, lemon or lime juice has a natural bleaching action that works on everything from underarm stains to rust stains.
