Unlike Lnie2D, AxesImage, etc. objects that are contained in Axes, QuadControutSet does not have a remove method. This makes it more difficult (and certainly non-obvious) how to remove a set of contours from a plot.

Yes, agreed that would be nice to have (though I haven't looked to see if there's a technical reason that's non-easy). We should find and consider any other classes that can't easily be removed as well.

Is there any workaround? I need one.
Being able to remove those QuadContourSets can be essential when producing animations.

This may indeed be desirable, but if you are computing a contour, my guess would be that you may as well clear and redraw the whole axes - contouring is expensive, even in C code.
