YES. Been there, done that. And I noticed it was on clean wet clothing coming out of the washer. I first I had thought it was happening in the dryer. (I noticed it on white towels). I even asked about it here and was told it was the transmission or something. I was still under warranty, yet the repair man found nothing. Said my model did not have a transmission that could leak oil. (I have regular top loader). But he gave me a few tips.
I cleaned the washer around the inside top, but the problem seemed to be inside the softener dispenser. The repairman mentioned that, and I said no no no, I never use that. But it was a bit dirty inside there, and maybe some liquid detergent got in there somehow, and mixed with some dirt and formed a sort of greasy combo. It was not a lot.
It solved the problem. I was so stumped, because I use bleach on those white towels, and they were coming out with stains. Good luck.
