mitsubitshi vs5003r projection tv

RECENTLY PURCHASED AT AUCTION CANNOT ADJUST COLOR CORRECTLY(TOO MUCH RED & BLUE) HOW CAN WE GET THAT SET BACK TO FACTORY SETTINGS. ALSO NEED TO CLEAN OUTSIDE SCREEN-WHAT DO WE USE SO AS NOT TO HARM TV? WHAT DO YOU SUGGEST WE CLEAN THE INSIDE LENSES WITH? THANK YOU
