When to Use Warm Water – For man-made fibers, knits and jeans, use warm water (90°F). Most of your clothes can be washed in warm water. It offers good cleaning without significant fading or shrinking. When to Use Cold Water – For dark or bright colors that bleed or delicate fabrics, use cold water (80°F).
Warm water can help to loosen and remove dirt and stains from clothes more effectively than cold water. This can be especially useful for heavily soiled or dirty clothes.
Warm washing machine water between 90 and 110 degrees is ideal for most of your laundry needs. Most of your clothes can be washed in warm water including man-made fabrics like polyester, nylon, and rayon items, and spandex. The water temperature is also ideal for natural fibers like cotton.
Cold: The cold setting is ideal for washing delicate items, dark colors, silks, and synthetics. Cold water is gentle on clothing and helps prevent shrinking or bleeding of dyes (1). Warm: The warm setting is commonly used for washing cotton fabrics and everyday clothes that wrinkle easily.
The researchers stress that (in health care settings, especially) laundry that comes in contact with vulnerable populations who are in nursing care, and those with infections, should be washed on the hot cycle, at temperatures above 140 degrees Fahrenheit.
60°C is the perfect temperature for killing bacteria, viruses and removing stains. This wash setting is also highly recommended for washing towels and bedding, but obviously this setting is going to increase running costs as the higher the temperature the higher the cost.
If you only remember one rule about how to avoid shrinking clothes, remember this: keep it cool. Clothes are much more likely to shrink when exposed to hot water or high dryer settings. Washing clothes in cold water goes a long way toward preserving the “off-the-rack” size.
The normal cycle is a bit more aggressive, so it's ideal for sturdy fabrics, like denim, bedding, towels, and most clothing. As the name implies, the heavy duty cycle should be reserved for heavily soiled items since it's longer and uses a high-speed spin.
Performing a 30-minute wash will also allow you to insert a few more clothes into the drum for a single wash. However, if you need to perform a large weekly wash, it's best recommended to use an ordinary washing cycle. 30 minutes also still won't be enough time to fully clean away stubborn stains from your clothes.
wash the clothing at a minimum temperature of 60°C, or hotter if the clothing is suitable for a higher temperature wash, and use your normal washing products.
Towels should be washed in the warmest water appropriate for the fabric according to the care label. Generally, warm or hot water is recommended for washing towels. Use a cycle specifically for towels or a normal/regular cycle.
Silk and other delicate fabrics
And along with your bras and silk underwear, it's best you don't put any other lingerie or stockings in the dryer either. These materials may shrink or become wrinkly because of the high temperatures inside the dryer, and it's next to impossible to reverse such damage.

Con: Hot Water Can Damage or Discolor Clothing
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.
A regular cycle is best for sturdy and dirty clothes, while the permanent press setting is fine for the average load. Use the delicate cycle for lacy and loosely woven fabrics. Use hot water for white loads, warm water for the average load, and cold water for bright colors.
Remember, fabric softener is completely optional, and your garments will likely pop out of the dryer feeling fresh, clean, and soft without it. However, “For some, it might make doing their laundry a little more fun to use an extra product that smells very good and is colorful,” Fulford says.
With high agitation and a lengthy cycle, the Normal cycle is typically the most intense washing machine cycle. Select the Normal cycle for everyday laundry items made of cotton, linen, and durable synthetics, such as sheets, towels, T-shirts, socks, and (non-fancy) underwear.
The Power Steam program is perfect for lightly soiled cotton, synthetic, and mixed fabrics items, effectively removing stains. The SpinDry/Rinse program rinses your load and spins it dry without detergent.
Does Cold Water Shrink Clothes? Cold water helps reduce the risk of shrinking clothes. Fabric fibers shrink as a result of being exposed to heat, either in the washer or the dryer. Use cold water temperatures in your washing machine and don't use high heat drying cycles if you're trying to reduce shrinkage.
Use warm to medium hot water on a normal washing cycle
However, the general rule of thumb is to put towels through a regular cycle at a medium-hot temperature, just hot enough to kill off any bacteria and remove loose towel fibres.
It might be possible for hot water to shrink certain clothing items to their maximum shrinking capacity after just one wash. Besides shrinkage, washing your clothes with hot water can also damage items by permanently causing color fading.
