Splendide XC Combo oiling our clothes?

Sounds like you, or someone, washed some clothes with something in a pocket or an oily rag etc. This would allow oil residue to coat the tub which would transfer to future wash loads. Use a degreaser such as Simple Green or Awesome and scrub the inside of the tub. Remember, the oil residue could be inside those little holes so you might not see all of it. I'd spray it liberally several times and then run a load through with no clothes. If you use a clean white cloth you'll most likely see the oil residue. Rinse thoroughly and you should be good to go. There's nothing in the washer that would allow oil into the tub area.....Dennis
