Dust blobs?

Hi, Hoping that somebody experienced can offer me some advice

My Pe5120 appears to have what look likes a big blur at the bottom of the screen, (probably about 10% of the width of screen). It is more noticeable in light scenes, and appears to move a little left and right.
It also has a big vertical line going down the left side of the smudge, and is kind of rainbow coloured. When on a white background, the whole thing reminds me of a puddle of petrol/oil in the sun.
Is this definitely a large dust blob? Its really annoying, and the definite coloured vertical line is particularly worrying.

I looked at the outside of the PJ and it has a lot of dust on the lens. It looks like it may have a few specs further in too, but not enough to cause such a distortion i doubt.

I hope it is just dust, but still worrying that it picks up dust so quickly.

Maybe I should do more dusting :P

Cheers for any responses

I think my benq6100 has similar light path.
One day a big dust blob appeared on screen. It was visible even looking in the lenses (with black glass to avoid eye damage... ), it was somewhere over the DMD. I gently use air duster around the lenses (do this with cold and powered off projector only), it was enough to move away dust.
