I was at training this last week with Shane an awesome new owner from Texas. I learned that the Pet Enzyme should be mixed in the two and one half gallon jug, that it has a long shelf life (unlike the past one). Mixing it all when you get it is good because if you mix it as you need it you’ll get mixed reviews because it separates giving you inconstancy in effectiveness. It has a long shelf life, that”s why we can mix and sell to the customer.
