The stronger vinegar is hard on a lot of things. Plastic stops slipping past itself very well, and it eats up the rubber.

I finished mowing the whole lawn this evening, with my dog and bird helpers. The dogs see how close in the path of the mower they can lie as I cross the yard, and the grackles come gather up the bugs I've maimed or outed. It's kind of cute, quite a lot of activity if you look. Someone just passing by on the street might only see me with the mower, not the rest of the activity.
