Keep in mind that, although many people have literally used a dishwasher to remove leaked electrolyte from logic boards, 'dishwasher' is a metaphor for what is needed. To be of use in an electrolytic capacitor, its liquid contents have to be water-soluble (or there will be no useful ionization). Water alone, then, will remove the alkaline goop (to use tomlee59's technical term) from an MLB. Warm to very warm clean water, alone.

Careful rubbing with a cotton bud (tip) may accelerate solution of crud from the board. Attention to detail, ie care, does the rest. Straight or branched-chain alcohols are not inherently superior to water in dissolving water-solubles. Thorough coverage of the whole board is advisable, as also is thorough drying of the board after copious washing. A week (as implied by tomlee59's note about haste) of passive drying in well-ventilated surroundings is not too thorough. Active ICs do not swim gracefully.
