How to get light dust out of primary mirror.

[Ahgii]

Hello, since i bought my telescope some time passed and some dust got on the primary mirror, the secondary, i cleaned myself with a fiber cleaning cloth, but the primary is harder to reach and not worth the risk cleaning with a fiber cloth. So i wonder what method is the best for getting that dust off without taking off the mirror? Another option i considered is dust off, should that do the trick or will it affect the mirror?

A little dust on the primary will do no harm, just leave as is.

+1 for Alan's response. I asked the same question a while ago because there was small specs of dust in front of bright objects. 

 

It it turned out to just be the eyepiece!

Never ever shine a torch on the primary mirror. It will ruin it forever. It won't affect its performance of course...you'll just not sleep as soundly. ;-)
