Beats me. Who knows what's in any of this stuff? No one's saying on their bottle. So I figure it this way:
For all of seven dollars, I can buy a bottle of PRS cleaner for a $4000 PRS guitar, and know that if there's a problem, it's not going to be a case of one company pointing the finger at another company. PRS is going to take care of it.
You're not going to hear, "Well, we specifically recommended that you use our cleaner, and you didn't."
Or I can use something else and take my chances.
Edit: I forgot to mention something. I've been using this stuff for years, on nitro PRSes, poly PRSes and V12, and have had no problems, no dulling, no scratching, no clouding. Leaves a nice shine, and doesn't leave the kind of shine that's greasy. So there's that.
My method in using it is to get a little on a microfiber cloth, apply it sparingly (a little goes a long way) and then wipe it off with a soft dry chamois or a clean microfiber cloth, though I kind of prefer the chamois. No rubbing is necessary, a single wipe does it. I like that, since the more one rubs a finish with an object, the more the finish abrades (if only microscopically at first), and eventually dulls.
And yes, I know, I'm way nutty about finish care.
