As you see, near the R there is a big white spot. This is new since today, cannot be wiped off.
The stem is dotted with these, less obvious on the other picture. My other ropp also has this since this week. What could this be + how can i remove it? Thanks in advance.

Note: it does not look like oxidation to me.
