OK since, I've used the Thiner/cleaner mix.  Works great but it gets a little expensive. Mostly been thinning with Windex.  Works great and cheap.  Use Distilled water.  Works but takes a lot of mixing to get just right. Thinned with Medea Airbrush Cleaner.  Works but I need to use it more to be sure. Not too sure about the techno stuff about what's said about using Windex but I that's been the winner for me. Between color changes and clean up I use the Medea Airbrush Cleaner. No clogging or anything.  For model color or game color works great with Windex on my end here.
