i was thinking that using a lint roller was good. but is that enough? or what do you use when the inside top get's dusty?

 

lint roller would be good for the bigger stuff-
and a damp rag should get the rest.
you can use a vinyl cleaner too if you want...
vinylex 303 or raggtopp would be some examples

 

if the 303 touches any of the metals inside that would be okay? thanks wanabe!

 

no problem on metal... wipe it off when you buff out the rest of the inside (with a dry clean rag).
do not spray the 303 on the top- for the inside you really do not need much product at all- just enough to make the rag a little damp. not like the outside- the outside you want a soaked rag... inside just barely damp- mainly to get any dust or lint that you didnt get with the first steps.
