White bedding might appear quite dull when washed, especially if darker laundry is mixed in.

Over time, body oil and sweat can cause the fabric of bed sheets to gradually yellow. Lotions and cosmetics also have a noticeable effect on the colour.

One option for whitening sheets is chlorine bleach; however, it is not particularly effective.

Bleaching might even result in yellow stains if the bedding items have traces of body oil on them due to a reaction with chlorine.

Furthermore, bleaching can damage bedding. Elizabeth Shields, operations manager of Super Cleaning Service Louisville, warned that “using bleach every time when washing is not always good”.

She further elaborated: “Yes, yellowish linens are a bit of an eyesore, but grabbing bleach every time you wash them can weaken their fibres. This makes the fabric susceptible to wear and tear, leading to gradual deterioration.”

Instead of bleach, Elizabeth suggests using white vinegar as an alternative method to brighten your sheets. She advised: “Instead of using bleach, try using a cup of white vinegar along with your detergent.”

She stated: “It'll help to brighten and soften the sheets without the need for harsh chemicals.”

White vinegar has natural whitening properties and works great as a fabric softener too.

Depending on the type of fabric and how dirty your sheets are, you should select the appropriate washing cycle.

Once the washing cycle is complete, transfer the sheets to the tumble dryer and opt for a low heat setting when dealing with delicate fabrics to avoid any damage.

Elizabeth further stated that air drying the sheets outside helps in enhancing their whiteness saying: “Not only will it give them a natural fresh scent, but it'll also help to brighten them up a bit more.”

But if you're still noticing your sheets looking a bit drab after they’ve been washed and dried, Elizabeth says it's probably due to “you missed removing pilling”.

Pilling occurs when loose fibres from the fabric get all knotted up, forming small balls or clusters on the surface. These can trap dirt, dust and other bits, creating a buildup of debris on the sheets and over time, making them seem “duller and darker”.

So before washing, be sure to gently remove any pilling using a fabric shaver or a lint roller. It’s a “small step that can make a big difference” and stop things getting worse during the wash and dry process.
