Should I use toothbrush and alcohol to clean a dusty logic board?

Texte:

I recently had a water spillage on the keyboard of my Unibody A1342 and as a result the keyboard is not fully functional. Using keyboard viewer I could see that the CONTROL key was constantly on, as well as SHIFT and ALT.

After reading up on my options I decided to remove and inspect the Logic board. (I know nothing about computer hardware) I cannot see any damage or corrosion, but I do see a LOT OF DUST and debris.

I decided to brush this away with an old toothbrush, and used rubbing alcohol (found a reference to this cleaning method) Is this a correct line of action? Is there anything else I can do?

Actually, before reassembling it I have left all the pieces, including main body of computer, trackpad, Hard Drive, battery and Logic Board in a sealed airtight poly bag with a dehumidifying product. Could this help? How lond should I leave it in there? Could it cause further damage?

Oh and will I need thermal paste to put the heat sink back? Or can it simply be screwed on?

Many thanks, and congratulations on this website/forum to help us solve our tech issues.
