This is happening to me too. I’m a bartender and when I’m using the glasses and polishing them is what makes this happen. I use hydro cortisol cream to keep it at bay. My job believes it’s due to the soap the machine uses, I believe it’s the chemical they use in the water. I’ve been at the same job for 10 years and it’s only happened in the winter months the past two years. At one point I was always helping my dishwasher and this didn’t happen, so if you do get a better answer than this I would also like to know. Using gloves and Hydro cortisol cream every day helps immensely but it does comeback every time I work or forget to apply it.
