Hello .If you feel competent and are not too heavy -handed try carefully easing the circuit board out of the box.give the whole thing,including the speaker a gentle dusting .Then get some white-spirit ,meths or mild solvent on a cotton-bud and wipe -over the circuitry.Remember though, that when these devices were designedthe airways were'nt so polluted with signals from mobile phones,e-mail and computer hunting forums!
