Does white vinegar over asphalt cause any harmful reaction?
Without knowing the exact makeup of the glue, it would be difficult, impossible, to say with any degree of certainty, what toxins would be emitted. Most of the glues out there say to use in well ventilated areas so after years, if you spray them with an acidic compound that partially soften them up or dissolves them, they're going to be able to give off fumes. Breathing misted white vinegar can cause lung irritation especially if you have lung problems to begin with. There are also disinfectants on the market which are better than vinegar.
