Fish Oil Pants Part 2

I have washed the pants in goo gone and extra detergent according to the goo gone bottle directions.  Yahoo!  It worked!  The dawn did not work.  The baking soda did not work.  The vinegar did not work.  The detergent alone did not work.  The enzymes for eliminating cow elk odor did not work.  But, the goo gone did!  Now they smell like orange!  Awesome!  I still have to work on the dryer.  Perhaps, the goo gone on a rag and dried in the dryer will work.  Can anyone tell me why dryer is spelled with a y? and not an i?  It makes no sense.
