TECH GURU's out there, how to clean Circuit Board?

Thank you very much, the Chemtronis and the Alcohol,they wont damaga the board correct? I am thinking I can remove any parts from the board so I might use a small brush and dip and clean kind a thing, would that work?

Thank you

Thank you very much guys, very helpful.
Just to clarify, I tried the micro vacum and compressed air and that did not work. There is hair and dirt still sticking, I bought this used, amp is around 6 years old so not ancient but used by some dirty bunch I believe.

I can get the grime off with slight damp cloth, and cleaned out what I could and let it there overnight and turned it on and used, perfect but I was trying to get the rest of the dirt off, I believe a small brush with the Chemtronis might work if done with care.

Well I rather leave it the way it is and use but its eating me, I am anal about my gear and I rather clean it up to make sure its well, thanks again guys

Last question,

I believe I can spray this carefuly over the board where the grime is and clean gently? It wont harm the parts that are presently on correct?

This might be better maybe? Anyone? See link below

Thank you everyone, Bombaywalla and all of you out there!
Very knowledgeble people and this is why I like forums such as these, very educational and helpful.

I used all your advise, paid $10 for the unlta wash from Radio Shack, $4 for brushes from the dollar store, cut the brshes up to enhance the stiffness and control .5 inch sprayed over the brush and cleaned process, never sprayed directly to the board only on some empty areas than needed.
Used a little alcohol or some areas with cotton swab and too my time and cleaned it up good. WORKED!
Images enclosed:

Believe me the board was originally brown in colour with dirt all over.... like the lable shown with the serial board #####, NOW ITS GREEN as original... Thank you very much. First 2 images shows cleaned board, last shows the cleaner I used, I also used rubbing alcohol or certain stuborn areas very little and with caution.
