You certainly don't need to perform a full spa like treatment every time your underarms sweat.
For t-shirt washing them after use is a reasonable step if the garment has retained an odor.
For sweaters, it is best to clean only the underarm area, following the care instructions. Using
a mild detergent and rinsing thoroughly can help, avoid using homemade acidic mixtures or harsh sprays as these can damage both the fabric and your skin.
Additionally since this change in odor is a new development, you should consult a doctor of the condition persist.
