So I went to treat my K-member bolts in OSPHO, I poured some into a small container, put the bolts in and let them sit for a week. The grease and oils came off and floated to the top and they turned black, but after a week, the acid turned to a green jelly like substance. I tried to wash it off with water and it got most of it but not all of it. I placed some more fresh ospho in it and I am getting ready to pull out the parts now...I will keep you posted. Tim
