This was casually mentioned in a different post, and it caught my eye
because it’s something I’ve often wondered about: What IS the cause
of that white residue that you see on the labels of so many early-to-mid
1980’s RCA 45’s?
In my experience, it’s impossible to remove; wiping it with a wet cloth
really doesn’t get rid of it - so it’s not water soluble.
Anyone have any insight?

Welcome to the board! Although I can't answer your question, you'll notice that the white residue is only found on polystyrene 45s. Vinyl 45s have their labels pressed into the vinyl, while styrene 45 labels are glued on. My hunch is that the white residue has something to do with the glue used on the label. Also, the problem is not exclusive to RCA. I've seen the same thing happen to other polystyrene 45s on various labels.

How obvious that answer should have been to me. Now that you
mention it, yes - it IS only on the styrene copies and I do see it on other
labels. (Epic and Elektra come to mind). Sometimes it takes a
different/outside perspective to realize something.
Thanks for accepting me to the forum. I’ve been lurking for a while and
I enjoy the info shared. And - if anyone wants to talk about the
country-side of Top 40, that’s the bulk of my collection. (1993 and older)

It's a compound put on the labels to keep them from
getting shop worn against each other in the record store.

William Brown, who knows more about these things than anybody, made the following comment on the Steve Hoffman forum about why the labels on styrene 45s differ from their vinyl counterparts:
...such labels were designated as "heat seal," with something put on the back of the label that, when heat was applied, would serve as adhesive and stay there, unlike the ones where glue or rubber cement(?) or mucilage (?!) was used.

I've used rubber cement to re-glue labels that have come
off, mid-60s Liberty & Imperial singles were big
offenders in that regard. Stuck better than the sparsely
applied cheap-o glue the pressing plant used.
