Fairly true, working with any chemicals overhead really... The main ingredient that gives oven cleaner it's action is Lye, or Sodium Hydroxide which is on the other end of the PH scale from acid, as one of the stronger bases coming in at 13 on a scale of 0 (Acid) to 14 (Base). Anything on the far ends away from 7 will get your attention on bare skin.

I can see your point, it wouldn't be something to take lightly and maybe I shouldn't have brought it up. As someone else mentioned elbow grease is an alternative.
