Results will vary based on the circumstances.
Also Testimonials, customer reviews, or actual results presented do not reflect the results of all users of any product. Past experience of one consumer does not guarantee the same result for everyone. This is always true with every product sold by everyone. All feedback is useful, too as directions are changed to influence actual results, and we always try to present in the directions the average results rather then what only a few will experience. Chemistry can't jump out of the bottle and do something without human intervention, interaction with metal or wood, etc.
