So the original magic erasers don't have any chemicals or solvents added?

Nope, I just give it a rinse to get any dust out of them.

Magic eraser is the way to go. I keep a box of them in both my stands. And one to clean outside of glass.

I tried the magic eraser and it didn’t do anything about the calcium. Although it did clean my top glass very well
