7 items you should never wash in hot water – laundry experts reveal how to protect your belongings from damage

If an item of clothing or a belonging is dirty, chucking it in the washing machine on a hot wash (meaning above 130 degrees Fahrenheit) is a common solution, but it can also result in shrunken, faded or damaged items.
Of course, hot washes are great for killing bacteria and sanitizing items that need a more thorough clean, but a lot of your belongings are better off in a cooler wash, at around 86°F to 104°F, or simply being hand washed in cold water.
We spoke to our experts for their tips on how to do laundry and they shared the seven items to never wash in hot temperatures to avoid a long list of damaged clothing and linens.
7 things to never put in a hot wash
1. Delicates

The most well-known items to keep away from hot water are delicates – think wool, cashmere, silks and underwear, as these can shrink or become distorted when exposed to hot water. Learn how to wash cashmere in our dedicated guide.
'Delicate fabrics like wool, silk, lace and sweaters can shrink and fade when washed in hot water,' says Ken Doty, cleaning expert and COO at The Maids . 'Try using a cold cycle for a gentle approach, or do hand washing.'
If you decide to wash your delicates, in the washing machine, we recommend investing in a mesh laundry bag, such as the Durable Honeycomb Mesh Laundry Bags for Delicates available at Amazon . These are specifically designed to protect your delicates from wear and tear in the washing machine, and are particularly good for extending the life of lingerie.
Daniel Brown, CEO at Handy Cleaners , recommends hand washing these items with Woolite Extra Delicates Care Detergent available at Amazon , as 'it is gentle enough for use during cold washing of these fabrics.' He also offers his expert-approved homemade solution, for hand washing clothes: 'Mix one tablespoon of mild baby shampoo with a gallon of cold water for a DIY gentle wash that's perfect for delicate fabrics.'
While you may think your sweaty gym kit belongs in a hot wash to kill off bacteria, elasticated clothing will fare better in a cold wash.
'Workout clothes are the exception here because they’re usually elastic and this type of fabric will shrink over time when exposed to heat,' says Alex Varela, general manager of Dallas Maids .
Your washing machine probably has a specific setting for washing sports kit, so opt to use that to ensure a thorough clean. Otherwise, pre-soak in baking soda and vinegar (one cup each) in a cold water submersion.
'Leather can be rendered stiff and brittle from repeated hot water washes,' says Doty, and it may lost its shape or even crack.
'To play is safe, stick to lukewarm water and a gentle soap,' says James King, operations manager at DeluxeMaid . 'If it’s just a little smudge or mark, instead of going all out with washing, use a damp cloth and a mild soap to gently wipe the spot clean.'
'I wear baseball hats all the time when I am outside working, and I’ve learned that you should always wash baseball hats with cold water – never hot water,' says Jeremy Yamaguchi, CEO of Lawn Love . 'The key with cleaning baseball hats is being gentle, otherwise they can lose their shape or endure damage on their graphics.'
Hot water can often cause some warping to the bill, and it can also cause the hat itself to shrink. Cold water helps hats hold their shape and size so that you can keep wearing them for years to come.
Can you wash memory foam ? It's certainly not impossible, but any memory foam pillows or mattress toppers should be kept away from hot water washes, advises Doty. 'Memory foam is another material that can get soggy and fall apart when washed in hot temperatures,' he says.

6. Dark and bright colors

Washing dark and bright colors in hot water risks fading, making clothes slowly less vibrant as time goes by.
'Instead, using cold water helps seal color into the fabric, thereby keeping your clothes vibrant, even after wearing them for a long time,' says Brown.
For a homemade solution, Brown also recommends adding half a cup of salt in order to set dye and protect against bleeding when washing new, dark colored garments for the first time. We recommend the Great Value Plain Salt available at Walmart for this, as it's affordable and high-quality.
7. Denim

'Denim is a tough fabric, but it’s not a fan of hot water,' says King. 'It can cause it to shrink, lose its shape, and even fade in color over time, so wash it in cold water instead. If you don’t feel like washing after every wear, spot clean stains and wash them less often to make them last longer.'
'Go for the gentle or delicate cycle to minimize wear and tear on the fibers,' adds King, to avoid making any washing machine or laundry mistakes . 'After washing, it’s best to air dry them to prevent shrinking, but if you need to use a dryer, opt for the lowest heat setting. Another cool trick is to add a cup of salt to the wash. That will help lock in the color and reduce fading.'
