Around here they use it to clean the waterers that are in the poultry houses.I've used it to get the hard water stain out of my dishwasher.I've also used tang and vit. c tabs when I couldn't get citric acid.Thats mostly what they are so they worked as good to clean with.
TSC also sells Rice Bran Oil. A little expensive, but when adding shipping online, less per gallon. I think when I bought a gallon a year or so ago, it was close to $19.00 per gallon. Horse people use it for a horse's hair to make it shine. Horses eat the stuff up like drinking a fine wine!
