What do you wash whites clothes on? What to Do. Wash whites separately. The best way to retain whiteness is to launder white items together in the hottest water the fabric will tolerate (water that is at least 120 degrees is most effective at removing soil). Choose detergent with a bleach alternative and/or enzymes, using the maximum amount recommended.
Do you wash whites with heat? Unfortunately, certain fibers can shrink and weaken in hot (above 130 degrees Fahrenheit) water, but won’t get a deep, thorough cleaning in anything considered too cold (between 60 to 80 degrees). The trick? “Wash white linens in lukewarm water, which generally falls between 90 to 110 degrees,” Nelson explains.
Do you wash white clothes in cold or hot water? Machine wash most delicate whites in cold water. Adjust the water level and set the machine for gentle or delicate. When using Ariel, you shouldn’t have any problems getting the perfect results even at 30 degrees.
What temperature do you wash white shirts? Make it hot. Generally, you should avoid boil washing – it wastes energy and can shrink your clothes. But with whites, hotter is often better, because it shifts dirt particles more effectively. However, use common sense and caution here – if your t-shirt says wash at 30, wash it at 30.
