How do I clean/erase SD card?

Solution
Android can be confusing because it describes part of the internal storage as an SdCard as well as an external one. If you do have a removeable card, buy a converter that makes the micro card fit into a full size SdCard port on a laptop, some PCs and a lot of printers.

Take all the data off that you want to keep and store it in the computer then take the card out and put it back in the phone. Don't format it in the PC unless you choose FAT32 - Windows format NTFS won't work in your phone.
