We moved into our new barn last fall, but the facility sat empty for about 2 years before we got here. God only knows how long all the pee and wet shavings had been soaking between the asphalt floor and the mats before then.
We’re in the process of pulling all the mats out and cleaning underneath them. We’ve been shoveling out the biggest chunks of coalified pee/shavings, then pressure washing the floors/walls to try to release the remaining yuck off the floor.
No matter what we do, there’s a gross, smelly sludge that is coating the floors. Is there some kind of chemical that can dissolve this nastiness? I just tried bleach today, I’m hoping that will work. But I’m looking for more ideas.
