Nobody wants expensive and high-quality terry towels to lose their softness in a short time.
However, this situation happens quite often.
What are the reasons why textiles can become stiff?
You are using too much powder.
You should always follow the manufacturer's instructions; adding more product will not make your towels cleaner.
But too much detergent can definitely lead to hardness.
Also, when choosing a powder for washing towels, you should give preference to products with a gel texture.
Air conditioner
If you are concerned about using conditioner for fragrance, use it sparingly. Too much conditioner can also cause stiffness.
Loading
If you wash a large volume of towels at once, it will be a bad idea. First of all, the textiles will wash extremely poorly.
The second reason for not doing a full load is that the towels will be too stiff.
