How do you clean your back pans?

let them soak in a mildly acid solution.

since my back pan is 2 1/2 x 5 I do the normal acid soak/baking soda routine. I then get the pressure washer out and clean the pan. No scubbing, I wouldn't try this with a soldered pan.

We go to Tractor supply and get Milk stone remover .we put one gallon total in our front,rear and steamaway. Build a small fire in the fire box and bring everything to a good simmer. After the fire is out the next day we drain and pressure wash everything. All pans and steamaway look like new.
Works for us

We have a waterloo turbo fisrt gen (6x16). We wash the back pan everyday. We rinse it and after we put filtrate in it and we have a pump who keep the filtrate moving. It stays perfectly clean for all the season. In canada we have a 5x14 wood fired evaporator. We clean it only at the end of the season with acid. We concentrate less so we dont need to clean it during the season.
