What have you tried cleaning it with
Just a magnet cleaner?

I cannot find what you trying to get, if its on the exterior of the tank, use some white vinegar and then a towel to dry it but if its on the inside, maybe get a blade or something to scrape it?

Looks like residue from glue or cement. I had a tank whereas the overflows were removed leaving a very similar effect. I tried to scrape it away but it felt like the glass itself and I could do nothing.
I wonder if a glass company ot tank manufacturer could suggest remedy?
