I should know better by now, but forgot tonight to thoroughly wash my hands after handling the “Dave’s Insanity Sauce” bottle. Hours later, I rubbed my eye only to immediately feel the burn of the capsaicin. Hurt like hell, trust me! Raced to the sink and splashed water on my face in an effort to shut down the pain. After a few minutes the sting was gone, but wow – don’t want to do that again!
