Here is the problem;
  I have 2 sets of bou horns that are blood stained. The velvet was not removed till after getting home.
Here what we tried;
   Soaking in a lake for 5 weeks. the racks are too large to use a tub, so no bleach.
   power wash at a car wash, hot soapy water and cold rinse.
   steel wool  course and 0000
  Any other ideas??
THANKS
