There are no user servicable parts in a complicated lens like the Canon EF-S 18-200mm, f3.5-f5.6 IS. It has 16 elements of glass in 12 groups, and if not properly disassembled and/or properly reassembled it can be easily damaged.
What I strongly suggest is either selling the lens as-is, with images showing the extent of the dust inside, or send the lens to a Canon Factory Service Center and have them do the cleaning job they are trained to do, and they do use specialized tools and diagnostics unavailable to the general public and general service folks. Canon will estimate the service cost before proceeding, if you wish.
The following is a direct link for Canon Factory Service Centers:

Just a few motes are truly insignificant optically, although they MAY make your lens less valuable on the used lens market.
My 17-55 E-FS has several dust spots on its inner elements and it takes stunningly sharp images if do my part properly.
As Ziggy said, Canon Factory Service will give you a quote for repair after they have seen and examined your lens. Then you can decide if it is worth your while to have it professionally cleaned.
It is not something you can do yourself.
