Super simple to use (make sure you follow the directions) and really makes a difference. I never seemed to have build up issues but I figured it’s good to “refresh” every once in a while anyways. As a first time mom I can’t even express how thankful I am that EVERYTHING GroVia has to offer is amazing, simple, and perfect for me/ my babe
My diapers had some build up. I did one wash and my inserts and shells came out so soft and fluffy! So pleased with the outcome!
