The act of using ones forceful urination to erase fecal residue left behind on the side of the toilet bowl by the toilet's previous user. Occasionally, more than one powerwashing session is required to completely finish the job.
I tried to get rid those skid marks that Jeff left behind by powerwashing them, but i could hardly make a dent in them!
