Clear phone cases are normally made from silicone—a polymer that’s popular for its inexpensive and flexible properties.

Then use a soft brush or a toothbrush to lightly brush the case until wipe the yellow stains off. Generally speaking, the normal substance on the phone case can be cleaned easily. But if it is yellow due to oxidation or similar reasons, it can not be cleaned.
