I use it all the time, and I've used it on acrylics, enamel (specifically Model Master), and laquer and haven't had any problem with it removing any of them.
I pour some in a container and let the parts soak for a while ("While" tends to vary from a few minutes to an hour or so). On stubborn areas I scrub it with an old toothbrush. When done rinse in running water and let the parts dry.
Unlike oven cleaner there are no noxious fumes to deal with and unlike brake fluid it won't eat up everything in its path. Just don't leave it on your hands for long.
