Hi there!
As per the thread title, are you going to send your DSLR to the service centre for cleaning if you found out that there is something not usual on your body?
As opposed to what? Leaving those spots there? Then it's up to you right...?
That's probably just dust, actually. If a blower is not working, then it's probably what is known as welded dust, and you would need wet cleaning methods to get rid of it. The servicing centre will do it for you (meaning travel time and a small fee). Alternatively, you can also DIY with sensor cleaning solution and some form of medium (sensor swabs, etc).
