ts - yes just go to CSC and tell them you want your lens to be wiped (dont use the word clean else they may dismantle your lens). they wont charge you for it.
as for the type and brand of filters, lenspen, microfibre cloth, lens solution cleaner, just go down to john 3:16 or cathay and they will recommend a whole suite of solution for you. and yes they will charge you for it.
p.s. you really sound like you need a nanny to hold your hand.
