I doubt the cleaners with the brushes would do any harm and might be a simple fix.
If that doesn't work you usually can get to the laser lens by taking the cover off the player. Unplug it first. If you look at the transport you should be able to see the lens, it will look like a small curved glass eye facing upward. Sometimes it will be hidden under part of the transport but you might be able to expose it by plugging the power cord back in, hitting 'Open' and then quickly unplugging the cable with the tray still in the out position.
If you have access to the lens, first try blowing any dust off with canned air. If that doesn't work, a Q-tip lightly moistened with rubbing alcohol or plain water and applied very gently should do the trick.
