Note, that, if you’re using PhoneGap, you’ll also have to clear their internal backup of the localstorage cache:

//Remove the localstorage db
NSString *path = [[[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:@"Backups"] stringByAppendingPathComponent:@"localstorage.appdata.db"];
[[NSFileManager defaultManager] removeItemAtPath:path error:nil];

//Also remove the cached versions
path = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];
for (NSString *string in [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:nil]) {
    if ([[string pathExtension] isEqualToString:@"localstorage"]) {
        [[NSFileManager defaultManager] removeItemAtPath:path error:nil];
    }
}
