I spray with acrylic paints and sometimes get buildup in spite of constant cleaning. Do you think soaking in mineral spirits will lift dried acrylic better than water? I’ve heard this is a good idea since mineral spirit molecules are smaller than H2O molecules.

I don’t think mineral spirits will cut dried acrylic paint. I have heard that a dilute solution of ammonia might break old acrylic paint loose, but ammonia can be hard on brass or aluminum parts. Acetone, available at hardware stores, can be used to soak items like spray tips.
