Before You Start

Before cleaning, remove the case from the phone and detach any accessories. Work in a well-ventilated area and wear gloves if you have sensitive skin. Test any cleaner on a small, inconspicuous area first to avoid potential damage. Typical cleaning sessions take 10–20 minutes, depending on the level of yellowing and grime. Do not mix cleaners unless the product instructions explicitly allow it, as mixing chemicals can create harmful fumes.

Rinse the case with warm water to remove loose dirt and oils before applying cleaners.
