Over time, dirt, body oils, and even detergent residues build up in your towel fibers, leaving them stiff, smelly, and less absorbent—even after regular washing. As a cleaning enthusiast with years of hands-on experience, I've seen this firsthand.
Fortunately, there's a simple, effective deep-cleaning method using everyday ingredients to strip away these hidden culprits and restore your towels to like-new condition.
Soak them in hot water with baking soda, soda crystals, and a bit of detergent. The results are transformative. Here's how I do it:

Notice the color of the water after soaking my freshly washed towels? Yes, they were clean out of the laundry—and still full of residue. Yuck!
Here's everything you need for this reliable deep clean:

- 60 g baking soda
- 60 g soda crystals
- 1 dose of washing powder
- Bathtub or large basin

1. Fill the tub with very hot water.
2. Add the baking soda, soda crystals, and detergent.
3. Stir with a spatula until fully dissolved.
4. Add your towels.
5. Soak for 4 hours, stirring hourly with the spatula.
6. Drain the dirty water, then run the towels through a rinse-only cycle in your washing machine—no additional detergent.

Your towels will emerge softer, fluffier, and truly clean. This method removes detergent buildup, fabric softener residues, limescale, and oils that accumulate in fibers over time.
The soaking water often turns colored or murky—perfectly normal and a sign it's working, regardless of intensity. You might notice a temporary odor as grime releases, but it fades.
Based on my extensive testing, this trick excels at deep cleaning all laundry, including tackling stubborn stains on kitchen towels. Give it a try—you won't believe the difference!
