Surprising things you should never wash in hot water

There’s no doubt that hot water serves its purpose when cleaning and sanitising items, but that doesn’t mean that it should be the default for every load. Choosing the appropriate washing temperature is essential for everything you wash, whether in a washing machine or by hand. The temperature you select can impact both the effectiveness of the wash and, in some cases, the appearance of your clothes.

While certain items should never be washed in cold water, some items should be kept away from hot water.

Wool garments

Heat and agitation are key in shrinking and felting wool fibres. The wool fibres mat together permanently, turning your favourite sweater into doll clothes when washed with hot water. Hot water can lead to unsightly pilling on wool garments. If you need to wash wool, use cold or lukewarm water with minimal agitation.

Denim

It is essential to remember that it is best to wash your denim clothes in anything but hot water. No one wants their jeans two sizes too small, so avoid washing them in hot water. It causes the denim to fade more quickly and get worn out.

Activewear

You may think that hot water is necessary for cleaning clothes that absorb a lot of sweat. However, most athletic apparel is designed to be stretchy, and the heat can break down the elasticity over time. This deterioration affects both the performance and the durability of the clothing.

Delicate clothes

Certain fabrics, especially the delicate ones like silk, lace, cashmere, or certain synthetics, should be avoided being washed in hot water at all costs. These materials can be damaged from the heat and cause them to lose their shape or texture. When exposed to hot water, they also fade in colour, lose sheen, and become more susceptible to damage. The heat damages the natural oils in these fibres.

Next time you do laundry, remember that cold water is your best friend. It’s gentler, prevents damage, and helps your clothes last longer.
