Does anyone have a recommendation for a way to clean the laser lens (or even if it needs it)?  My last player was a top-load and cleaning was easy.  Also, is there battery in the player that will need to be replaced?  I am not sure if there are any memory functions that require full time power.
I really like this player and the  B135SST2.  Final purchases.  Only speakers left if my wife will let me.
Thank you.
