There's nothing more disappointing than reaching for a towel, only to find it stiff and scratchy. Towels can become uncomfortably hard if not laundered correctly.

The most common blunder when washing towels is using excessive fabric softener, as towels are highly absorbent and soap can easily accumulate in the fibres. Overusing fabric softener and overfilling your washing machine prevent the towels from rinsing properly, leading to residue build-up that causes the fibres to clump and harden. However, there's no need to discard any worn-out towels.

Cass, the founder of Frugal Family, has revealed how to rejuvenate towels by deep cleaning them with two simple household ingredients.

She said: "Non-fluffy towels are super easy to fix though and just need a couple of things you'll probably already have in your kitchen storecupboard - white vinegar and baking soda."

So, how does it work?

White vinegar is remarkable because it not only removes any build-up on the fabric, but it also acts as a natural fabric softener, relaxing and fluffing up the fibres.

Baking soda, being abrasive, helps break down any soap coating the towels.

It's also a natural alkaline, which balances the pH levels to restore the softness of the towels.

Using white vinegar and baking soda is an inexpensive, gentle, and eco-friendly method to revive towels.

However, it's crucial not to combine the two ingredients, as this will diminish their effectiveness.

For the ultimate towel rejuvenation, a double-wash process is required, which will restore softness to your towels.

Here's how you can make your towels fluffy once more:

Start by adding 120ml of white vinegar into the detergent section and run your washing machine at its highest temperature setting.

Opt for a 90C wash if possible and avoid using any laundry detergent or fabric conditioner during this cycle.

Cass said: "The first thing to do if you have towels already in this state is to do a towel refresh wash which is basically a high-temperature wash that will strip off all of the layers of product from the fibres of the towels so when they're dry they'll be fluffy once again."

When the initial wash is complete, initiate a second cycle, this time incorporating baking soda into the drawer of your washing machine and maintain a high temperature for the best fluffiness.

After completing both cycles, hang your towels outside to achieve optimal fluffiness. A brisk breeze will help fluff them up further.

Alternatively, if conditions necessitate indoor drying, like in a tumble dryer, choose a gentle heat setting.

Cass said: "Dry outside on a windy day. It's really important that you do this or at the very least pop them in your tumble dryer if you have to, but if you put them over the radiator or your indoor dryer, then they're not going to dry as soft."

Post-wash, your towels should emerge beautifully fluffed, superbly soft, and wonderfully fresh without resorting to harsh chemicals.
