Try spraying a solution of 1/3 Clorox, 1/3 hot water, and 1 cup/3 gals of
TSP. Let sit for half hour and hose off. Cleans most all stains. If this
doesn't work get phosphoric acid, sometimes called concrete cleaner, at HD
or Lowes; if you use this stuff, however be prepared to flood the entire
concrete pad since it will brighten the area you apply it to.
