Orange gunk on bathroom ceiling

My bathroom (and bathrooms of other people I know) has spots of
an orange, resin-like substance on the ceiling and walls.

What is this stuff? Mold? Oil-based paint residue coming through
the latex paint? No one I know seems to know.

But most importantly: how do I easily remove it?

I've tried scrubbing and scraping, and that works with a fair
amount of effort. Using a heat gun seems to help. I've tried
mineral spirits, turpentine, rubbing alcohol, and a citrus-based
solvent without any additional success.

Right now, I'm thinking of just using a power sander to get rid
of them (I'm about to paint my bathroom).

Also, how do I prevent them from forming with my new paint?

Many thanks for any answers.

I second the water and steam from the shower/tub theory as to the cause.
I used to wash mine off with straight pinesol a couple of times a year.
Two years ago I redid the bathroom, I washed the ceiling in TSP first
before painting it and so far they haven't come back. (The fact that I
got rid of the teenager, who took 35 minute showers everyday, at the
same time may have helped too)

I used to have that problem in my bathrooms... it went away when we quit
smoking cigarettes in the house. If you have smokers that may be the
solution.

Another cause may be mold growing in moisture condensing on the wall. A
wash down with tsp solution and increasing ventilation should fix that.

I go along with everybody who says it's from steam (from the shower)
condensing and forming water droplets; whether the actual substance is
from something percipitating out of the water or being dissolved out of
the paint, I don't know (but suspect the latter), but the best way to
keep them from coming back is to have a good fan in the bathroom and make
sure to run it long enough after every shower that you don't have the
condensation on the ceiling.

Had that in the downstair bathroom in my parent's house. Since they
vanished almost instantly when hit with any sort of spray
disinfectant, I was inclined to believe they were some sort of strange
mold or mildew.

I had the same problem. They were hard water rust spots that washed off
easily.

I know this is super old, but this problem plagued me so I'll answer.

It's obviously not mold, because it can't be killed.
It obviously is not hard water/rust because it is sticky resin and not in contact with metal.
It is obviously not cigarettes if you don't smoke cigarettes.

The most likely explanation when is that the person who painted the bathroom used general-purpose paint instead of bathroom paint. The moisture is going to cause substances within the paint to separate out. No matter how many times you remove the stains, they will keep coming back, at least until you have scraped all the paint off your ceiling.

A less likely explanation is that honey is seeping through your ceiling from a bee infestation. I wouldn't recommend tasting the orange paint-resin, but that would be a way to exclude honey as a cause.

Not with water based paint which most use.

Depending on the tiles it could be glue.
