How many many more first hand experiences do you need than people here before you just buy a bottle and try it yourself?
If you aren't willing to try it and see for yourself, then I dunno what to tell you.
Full disclosure: I think most other Ceramic Speed products are gimmicky and a waste of money based on my experiences with them, therefore I do not use them.
I gave UFO Clean a try myself and have been pleased with it, as well as everyone else I know using it. I am not a fan of their stuff in general, but this particular product does what it says. Therefore I use it.
Do what you have to do. If you wanna use mineral spirits go for it.
Too much over thinking in this thread. Some of you want to make this more complicated than it needs to be.
This entire process is supposed to be simple. UFO Clean adds to the simplicity.
