My daughter was a very messy eater! Most days she ate without her high chair cover just to save me from another trip down to the laundry room. One afternoon when my mother-in-law was visiting, she caught me in the kitchen doing a "deep clean" of the high chair with cleaning wipes and suggested that I pop that thing right into the shower stall. While running the shower water, she used mild dish detergent and a cloth and taught me how to clean a high chair the easy way. It was a great trick! She raised 8 kids so her advice is always spot-on!
