2 part B in my box

I purchased a gallon kit today at hobby lobby. It sat in my car for a few hours while I was at work so it was pretty warm when I started working with it. I made a batch thought it was pretty runny (again pretty warm soo) poured it in my molds and when I went to move the bottles I realized it was 2 bottles of part B. Outside of losing time and product how do I clean the molds??
