For larger cracks around window frames you can use sealant or putty to fill them up. All manufacturers of boilers installed and worked on including to name a few. I tried baking soda/vinegar the other nite - the clog got worse! i still haven't been able to use my shower maybe i didn't use enough of something? or maybe the standing water in the tub diluted it too much? i'll try soda.
