So I decided to try a natural method I had read about. It had rave reviews...
and scrub I did. and this is what I got.
It is better, altho in person I didn't think it looked better at all., but there is still a very dark ring around the drain, and lots of brownish areas.
So I had read that Mr. Clean erasers would work. Then I remembered hearing they had formaldehyde in them, so I researched it. They only have one ingredient, Melamine polymer.
It is not a chemical that the eraser uses, it is the fibers of the eraser that do the cleaning. Kind of like a super fine grit sand paper I suppose. Anyway, I gave it a go.
Those erasers really are magic!
Have a blessed day!
