Hello! I have the exact same problem, although I do have some crusting and itching once in a while in the same place behind my right ear. What I do is when I shower in the morning, I take a pair of rough bath gloves, soap them up, and gently scrape away the dead skin.
When they are absorbed, they can be released in sweat through skin. Foods like yogurt, onions, garlic, red meat, cabbage, spices like coriander, and asparagus may result in increased body odor when consumed in large amounts. When you have a diet rich in proteins, you may have vinegar like smell on sweat.
You Get What You Put In. The odors that stink up your washing machine come from the clothes you put in it. Soap residue and hard water contribute to the foul odor. Sweat, dead skin cells, pollution, and bodily odors will eventually make your washing machine smell bad. Foul odors in your washing machine are caused by a film of scum. It may sound disgusting, but that disgusting layer of filth are the stains and dirt that come off from your clothes.
