You'd have to fully disassemble the lens, which I strongly do not recommend doing (especially the plastic lens bodies).

Have you noticed an effect on your images?

Unless you have an issue with it showing in your photographs, don't worry about it. Very doubtful you can clean it yourself without trashing the lens. The only alternative is an expensive Canon repair.

Thanks for the replies so far. I am worried some of the dust will now end up in the camera body. I was hoping all I would need to do is to remove the front element? If they cannot be cleaned via DIY any idea what canon charge for cleaning them?

Disassembling and reassembling a zoom lens is no joke. It would probably cost more than the lens is worth.

There is no reason for the dust to work itself from the interior of a lens into the camera body. And if it does, the sensor is (relatively) easily cleaned.

Relax. Take pictures!

i know this post is old but i tool will like to if there is a DIY guide on how to open and clean the lens.

Because of the fungus build up on the inside of the glass both front and rear i get a blueish haze when i take pictures also the lens experiences trouble to auto focus when zoomed in anywhere after 70mm.

I dont mind the risk of cleaning the lens myself as i only paid $200 US for it and it more expensive to get it professionally clean than the cost of the lens itself. Also i'm looking to upgrade to either canon 17-40mm, canon 16-35mm or a sigma alternative, so it doesnt bother me if the lens become useless afterwards
