We have used the nu:ju facial cleansing cloth for a week and sent it to an independent lab to check it for germs. Here are the results.
For one week, we only used the nu:ju facial cleansing cloth. Without soap or washing gel, only with water. After that, we also wiped the wash basin. Then we sent one used and one unused cloth to an independent lab to check it for germs. We wanted to know if the silverization really can prevent harmful germs and bacteria from setting.
The lab report shows that the unused towelette is not objectionable from a hygienic point of view. But also the used towelette only shows a small total number of aerobe germs of 120.000 KBE/624 cm² (one towel of 624 cm² weighs 8,125 g).
For comparison: the total indicative amount for packaged mixed salad is at 50.000.000 KBE/g
