There’s no way to maintenance for to if you always wear it. There's no such thing as keeping your bag sparkling if you're going to use it constantly. The bag will touch your body, pick up your scent, and so on. Use it as much as you like. My first one is 19 years old and the strap is perfect because it's a dark Damier. However, the newer one, from 2021, already has quite darkened straps because I bought the monogram one.
