i have noticed after cleaning boards w/ 91% ISP that there is a white residue on the components and slight haze on the board. my process is to clean the board before hand w/ 91% ISP, not handle components by any leads and most of the time i am placing them by tweezers as they are smd (qfn, tqfp, 0402, 0603, etc) and to only touch the board on the sides, not near any contacts. to clean, i use a new toothbrush, pour the ISP on the new toothbrush and then go over the solder joints. the boards work excellent, and i have no electrical issue w/ the soldering technique and am always trying to refine it to get it better, but this cleaning is bothering me. guess i get a little anal about my projects...
i use this solder:

any way i can have a clean board w/ no white residue/haze would be greatly appreciated, and hopefully w/ easily accessible household/drugstore items
thanks,

edit - the board needs to be dry after the cleaning as it will be exposed and not 'sealed up' at all, but not rain, just outdoor weather that one would be in flying radio controlled models around the globe
