We try our best to design a product to be as resistant as possible to any kind of external damage, which includes resistance to scuffs, dirt, and discoloration. Unfortunately, there is a limitation when it comes to it being dirty over time depending on the environment you use the case in.
Like all products, it is noticeably easier to spot something that is dirty when it has a brighter color in contrast to a darker-colored one. For example, a pair of white shoes will look dirty if not taken care of properly in comparison to a pair of black sneakers.
For daily cleaning, we suggest using wet wipes. To sanitize, wipe it swiftly with a cloth and a small amount of rubbing alcohol (less than 75%). If you have a product with a printed design on it, we suggest avoiding the printed parts while using rubbing alcohol.
If cleaning it with the suggested method above does not solve the issue, please contact us and they can help you with this.
