Errh, gentlemen! Once more LDD rides to the rescue. The detergent will
dissolve and vanquish those nasty oils!

Leif, Good idea, it may work very well. I agree with vanguish, but dissolve?
I'm feel compelled to correct your chemistry. Only solvents can dissolve a
substance (note the common root word) and detergent is not a solvent. It is more
likely the detergent is saponifying the oil. Dan
