Excellent, thank you. Hardest part was taking it apart. My particular remote (Yamaha RAV463 ZA11350) had more than 4 tabs. Had to start at a lower corner and and work my way up one side and then the other.Took two sets of hands. Helper held remote while I applied small flat screwdriver, thin metal putty knife and then larger flat screwdriver once we got it started. Works great now that it is gunk free. :-)
