Trick....wash a area with mild soapy rag, let dry.

Take a rag with ammonia on it, straight out of bottle, wipe area you cleaned a few wipes with ammonia rag. If paint comes off on rag, you have latex paint on that area, oil paint will not come off on the rag.

Ever have a customer complain that when they wipe there walls down, that they wipe paint off their walls? Tell them to stop using a cleaner with ammonia in it, and the paint will stop coming off their trim, and or walls.
