To keep your phone case looking new, wipe it down regularly with a damp cotton or microfiber cloth. For everyday dust and fingerprints, that's all you need.
If something stickier ends up on it, add a small drop of mild dish soap to the cloth, gently wipe the case clean, then go over it again with a fresh, damp cloth to remove any soap residue.
A quick clean now and then keeps the print sharp and the case looking like the day it arrived.
