Ya some acrylics don't like lacquer thinner, some don't like alcohol. Most will get along with warm water with a little dish soap in it. I made a cleaner with a little windex in water and a drop of dish soap that works with most acrylics but you really have to rinse well after. I have not tried either with Mission Models but most likely they will work.
Edit: I found an online tutorial from MM and it included cleaning. It says that alchol and ammonia break the paint down but if you clean with those items included it will clean but you really have to rinse well. That's basically what I do anyway since I clean my airbrush at the kitchen sink, I just keep flushing and spraying with warm water. I take my airbrush apart periodically but all through a build I clean it this way using my own cleaner or sometimes straight 91% ipa depending which acrylic paint it is.. Lacquer and enamel obviously get lacquer thinner as the cleaner.
