I don'y know anything about the glass top stove cleaner theory, I don't have a glass top stove. I am a big fan of the Mr. Clean Majic Erasers, all you need is a little bit of spray cleaner (I use either clorox greenworks bathroom cleaner or Seventh Generation bathroom cleaner) and dampen the eraser, they take the scrub work out of tough cleaning, I won't ever use anything else to clean my tub with! They also work great for dark marks from shoes left on vinyl floors, my apartment floors were discolored when i moved in and know you wouldn't be able to tell, not to mention our bathroom tub was grey, and it's white again, the people that lived here before us obviously didn't clean it very well when they moved out. Anyway, good luck with your bathroom!
