I have a pail of speakers taht live in the kitchen, they play podcasts on such when im suffuring the pain that is kitchen work. so i have noticed that they have ccumulated a layer of that fine kitchen grease that comes from cooking with olive oil too often, so i think lets clean them. turns out not so easy as i thought. ive been scrubbing away like a crazy sob and while its coming off its painfully slow, painfull to my hand too. so im sure others must have encountered this problem too, what to use on them? i cant pick the speaker up and soak the thing in soapy water so is there some magic technique or chemical i can use?
