They will not clean the lens on the inside. It is not worth it. If you are from the USA, go to the Canon USA website/support and fill out the form, they will give you an estimate of how much it will cost to look at it.

Please advise us and the Canon forum at large the exact model lens you are inquiring about. Please specify if you have the version I or II, the Image Stabilized or USM version.

Canon recommends "... periodically having your gear cleaned and checked by a Canon Factory Service Technician. Best of all, if during the CMS we find something that requires more than just a cleaning to correct, we will contact you with a description of the problem and what we recommend to do to fix it."
