What are those white / clear "crystal", which forms the door of my shower?
I recently took a long leave and when I returned I realized that kind of white / clear crystal small mounds looking things formed in the metal frame of the door of my shower. When cleaning that I realized that the metal had been eaten below! Does someone has an idea of what I see here? Thank you.
The crystals are white mineral deposits. You will probably have hard water. Remove with a cleaner that removes lime away or CLR Cal
