An expert goes over steps to minimize damage to clothing from antiperspirant.
Antiperspirants can definitely damage clothing. White cotton undershirts and dress shirts become yellowed and stiff. There really is no solution to this problem. The clinical strength products are more likely to cause these problems than regular antiperspirants and the more antiperspirant that is applied, the more fabric damage that occurs. The problem can be minimized by laundering the clothes immediately after wearing, but this is not practical for many patients.
Antiperspirants can also damage other natural fabrics such as silk and rayon, worn by women. If this is a problem, armpit shields can be worn underneath the garment that help absorb additional sweat and protect the fabric.
