think about what exactly this stain is. It is probably the dyes being
moved around by the water. In which case, you don't want to 'clean' the
stain merely redistribute it back to what was there originally.
We once had hand painted wallpaper that cost over $300 per roll back when
$300 was more like $1,000, seriously. This paper [at least to me was pure
cr**] was chalky one of the stiffest backing I'd ever seen, more like
cardboard, with instructions of 'never let water touch the paper' say
what?! and use low, to non-existent water base glues! I actually put it
up with double edged tape!
I have to tell you it was beautiful, but...
One of the small pieces got water on it, and sure enough the dyes migrated
out following the water's edges. I don't think 409 would have done
anything here but make it worse. So, my point is, *if* it's truly a stain,
clean it; but if it is the dyes migrating out to the edges, be CAREFUL!
Working with this paper was like having a water spot on one of my wife's
silk blouses! Would you put 409 on that? No. You just add water and try
and blend the spot in.
