I don't have to worry about losing the pattern from my liner on this one, the stains are so far above the waterline, that there isn't even pattern there; it's just plain blue up there with black stains.

As soon as I can get out of this house & buy another magic-eraser,
( I used the last one up removing the picaso, van gogh, & renoir - crayon drawings from the walls...lol).
.. I'll let you all know how well it did on the stains.

unfortunately all three little darlings have the pox
( chicken pox even though they were vaccinated for them!), so I'm stuck here for a while.
