My brother says this will damage polyurethane.

My bands old guitarist says otherwise, but he's an idiot so yeah.

Anyone know what this does to the polyurethane?

polyurethane is pretty much indestructable. not much can hurt unless youre trying to hurt it and rubbing alcohol dosent make that list.

My Yamaha baby grand piano has a black polyurethane finish. Recommended cleaner? Windex.

Or like a mixture of several highly potent chemicals... Whatever works, right?

NO NO NO NO NO

LYSOL, WINDEX, WINDOW CLEANERS, ORANGEGLO (R.I.P. Billy Mays) = VERY BAD FOR GUITARS.

They cause odd discolorations under the finish in the wood.

For some reason I've found that guitar polish works pretty well... imagine that.

I'm not suggesting you actually marinate the guitar. Geez.
