Playing shirtless or in short sleeves in the summer will do a permanent number on your guitar, unless you keep up on the wiping down religiously. Sometimes just blowing your breath on it in a moist enough environment 30+ % and vigorous wiping with a non treated actual guitar cleaning cloth is all you need. Polishes are just smelly crap as far as I'm concerned, will never buy another bottle of Martin guitar polish, Gibson polish (I used to really like that one), Goerlitz Guitar Honey, etc. All toxic.
If I really need to clean some old crap off, like when finally selling a guitar and bcause Covid, and I don't particularly dig 20 years of someone else DNA all over the instrument I'm about to get shirtless and personal with, I reach for good old Meguiars Cleaner Wax that has no Silicones in it. If I need more, I go for the Fine Cut Cleaner, If I really want to go through some bad scratches like on my Dano 3021 Page model when I bought it it looked like someone tried to wipe the top down with a Brillo pad, I got for the Heavy Cut Cleaner, and all the way back out to the Cleaner Wax. Also, I will not hesitate to wet sand finish if I think it will benefit from it.
I bring the polish out of the Nitro by rubbing it at super human speeds, you can can really get some heat going, you can even get it to flow a little if you have to over a booboo.
But make no mistake, once a top is clouded in the corner from you arm, from having been left that way for ten plus years, even after all the rubbing in the world, you will still see some clouding.
Nitro laquer lets the wood breathe and age and that's good for tone. If Guild thought we couldn't handle some cosmetic imperfections from use, they would have sprayed there with Poly like millions of other guitars, but it is higher maintenance, and also reacts to things, like guitar straps left on in the case, etc.
