How to clean a memory stick?

[Blue]

For my HACKED psp. I have a recovery startup menu on it. Since mem stick is curropt, it cant run the menu, or anything else, basically its like i bricked it.

It stick isn't corrupt,if it was your computer would still recognize it,but you couldn't do anything on it.(Save,access date,etc.).If you can,take a picture of the connectors and post it here.
