Keep those nozzles clean, folks! By ensuring you wipe away any excess adhesive, you will be prolonging your bottles! CAUTION: Cyanoacrylate and cotton are not safe products to interact! These wipes are unique as they do not have the loose fiber that can be a culprit to the reaction. Even still, I'm recommending to always be cautious when exposing adhesive to any cotton form. I simply wipe nozzle clean, keep separate from my main garbage whether in a sealed glass jar and I go one step further and saturate with water (ONCE IN JAR) to ensure the cyanoacrylate is cured to prevent any response.
