The rosins in the solder are now trapped inside the connection and will start corroding the connection. The rosins react with oxygen to begin the destructive process. This may take a long time --- 5 or 10 years, but the corrosion with start eventually. Not a good idea for aircraft quality connections. Commercial printed circuit boards usually run through a tank to remove any excess rosins from the wave soldering process. Skip this process and your boards will start corroding in a few years or less. I know that most electronics people who solder usually skip this cleanup process but MIL SPEC soldering requires it as well as most PCB processes. It's a bit like the "final straw that broke the camel's back" scenario. It is best to use normal solder and then run a cloth over the connection. The cloth is dipped into rosin cleaner or MEK which removes all excess rosin to prevent corrosion. Best regards, D.C.
