Remove sweat smell in clothing with disinfectant
For whom the vinegar, citric acid and soda tips do not work (as was the case with me) here's a (hopefully) new tip:
Wash the garment in the underarm area after washing with plenty of disinfectant (such as Sagrotan) and wait until it is dry. Then soak for about 6 hours in Hygienespüler: Voila! All muffle bacteria have blessed the time and will not come back so fast! So it was with me and now I can wear my tops happy again!
