I'm in a holding pattern due to rainy weather. Deck has been cleaned and brightened, and at least one squirrel has found something to his liking in the cleaned wood. Twice I've caught him (I mean I've spotted him) hanging upside down on the spindle and actually gnawing on it.
What's in the RAD brightener that he likes to eat?
It is citric acid based so it would be like chewing on a lemon. Does his face cringe up?
