Sound advice above.

I would only add you get a free clean under warranty so when you can get it back to a Canon service centre and let them clean it for you. Things are best left as they are for now until you can do this.

The kit you bought is purely for lens cleaning do not use it on the inside of the camera body.  Use it for cleaning filters and the front part of the lens.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
