Hi John, your problem seems very unusual. If you get a respnse from Thompson's, I hope you will post it here for us all to learn what they say. Hang in!
After several years our deck faded and the seal brought the gray color out. We had to use a stain seal after that.
Use a degreaser
I think you might need to lightly sand it down to get it all off
I would try a white vinegar and dawn solution in a power washer. Do not use high pressure just enough to get the residue off.
Did you do it when the deck was wet or damp? May be mould?
