Even if the result of the wash ball is controversial, many users are convinced of the positive effect.
I myself believe in its effects.
The wash ball is filled with mineral ceramic balls and the smell and the effect lasts up to 1000 washes; it also helps to save some detergent.
Regardless of the disputed opinion or the test by Stiftung Warentest, it is logical that this ball loosens and "massages" the laundry in the machine, which leads to better washing efficiency.
DO NOT USE ON KNITTED OR CROCHETED PARTS MADE OF WOOL OR WOOL BLENDS !!!
It is also very suitable for washing items made of felt knitting yarns.
The wash ball is available with a neutral (floral) scent in pink and with a subtle lime scent in yellow.
