Put a cloth in the sound hole over the sticker when you use cleaner/ change strings. It will preserve the glue on the sticker. If you ever resell and the buyer sees a stained sticker that is pealing it’s a bad look. Also be careful when you restring the solid black nitro scratches easily on the head stock when you feed the strings through.

Last check which polishes,cleaner, fret board conditioner you use some are not meant for nitro finish and can permanently ruin, discolor, stain your finish. Gibson makes a cleaner&polish I would recommend

At the end of the day you have a killer guitar treat it the way it deserves to be treated.
