our muckheap was removed yesterday and the JCB doing it has spewed oil/diesel all over my yard. I didn't notice until i went to start power hosing the sh*t the driver welded onto our yard :stomp: i've power hosed the whole yard however the oil is still there. i don't want it contaminating our hay (we have large bales dropped on the yard) or causing the horses to slip. My first thought was to use fairy liquid but i don't really want that going down the runoff. Thereagain it can't be any worse than the oil! i know you can get more environmentally friendly detergents, or maybe those absorbent mats? any experiences?
