Put some alcohol on a rag and rub the paint. Latex will come of, oil base
won't.

I will need to paint the house trim this year and since we just bought
this house I'm not sure what type oil or latex was used. Is there
anyway to tell? I can't ask the previous owner. I can never remember
which can't go over which.
Thanks in advance. You all are so helpful!
