Clean Concrete Bonding Agent from Dutch Ovens

So, my wife mentions she noticed a mess in the garage. I bottle of Lanco Concrete Bonding Agent, the white acrylic stuff, got knocked off the shelf when something fell over and the old cap cracked open and dumped almost the entire gallon on a stack of two Lodge dutch ovens, completely filling the lids and overflowing down the sides. By the time I see it, the white liquid on the top lid is already mixing with some color from the seasoning. Even though the lids were on, some leaked inside of them. I took them outside and hosed them off, but some has already started to harden. The stack next to it were in dutch oven bags, so just the outside of the bags got contaminated. Hopefully those will come clean in the wash, but some would not budge with the hose. Luckily only two of the eight ovens got the liquid on them.
Anyway, I have not been on this forum in years, but I figured I would pose the question. How would you clean these ovens to get everything off and make them safe again? My usual method is in the self cleaning oven and then re-season. But I am not sure if I want to do that and have burning acrylic in the house. Maybe I could borrow the neighbors pressure washer first and get off what I can before a self-clean cycle. I also have a jug of phosphoric acid I have used to remove rust, but these have no rust.
Ideas?
