what do you guys use to "quickly and easily" get the sludge out of the bottom of semi tankers that we have been using to haul hog slurry??

We needed "...just a few more gallons to finish the field"...........so pumped into the No Man's Land portion of the pit bottom...............and pulled a lot of "sediment"..........which I think pretty much stayed in the bottom of the tankers anyway.

But.........the problem still is...........how to relatively easily clean out the tankers.

Fill with water and add 10+ gallons of detergent, and let them sit for a few days?

Are we going to have to put in some kind of agitation device in these tankers for the future while transporting--------your experiences??

Thanks.

(Applicators don't have much..........probably due to the pressured agitation??)
