● Dip a toothbrush or a microfiber cloth into the soapy water and use it to scrub the inside, outside, corners, and crevices of the case.
● Rinse off the case with warm water and dry any remaining water stains with a soft cloth after the overall cleaning.
● Place the case in a ventilated location and wait for it to dry completely.
#3: Use alcohol to clean the case

Why do transparent phone cases turn yellow?
Transparent phone cases can turn yellow due to a few reasons.
Ultraviolet (UV) Radiation: frequent outdoor use and exposure to sunlight can accelerate the oxidation of the case’s surface, leading to gradual yellowing, UV rays can also cause decomposition of polymers and oxidation reaction with oxygen.
Chemical Contact: certain substances like cosmetics, cleaning products, and oils can slowly penetrate the case’s surface, causing yellowing.
Natural Grease: when sweat and body oils accumulate on the phone case without timely cleaning, it can lead to bacterial growth and the salt component in sweat can accelerate yellowing.
How can you prevent yellowing of a transparent phone case?
Regularly clean the phone case: You can use warm water with a soft cloth or toothbrush to thoroughly clean the phone case. Baking soda can be used to remove stubborn stains, while alcohol spray or a soft cloth with alcohol can clean bacteria.
Avoid direct sunlight and high temperatures: While using phones in sunlight is inevitable, exposure time should be limited, and phones should not be placed in direct sunlight. For example, if the phone falls into water, it should be placed in the shade to dry instead of being exposed to direct sunlight.
