I am in the Poo!! Help.

[Booty]

Right, Ladies and Gents I need some serious help please. Strange request but anyway. I have inadvertently 'placed' one of my towels from the garage into the washing pile. It's gone through the wash and coated Flossies 1 year old washing machines drum with oil. I did not know there was any on the towel t.b.h. but there was. It has coated the three plastic arms that sit around the drum ( if your looking into it they run from front to back). To touch the arms they fell 'sticky' and rough. So far I have done the following.

1, 95 degree wash with washing gel......nothing oil still evident.
2, 2 x dishwasher tablets at 95 degrees.........nowt again still there.
3, scrubbed the arms but it seems the oil has 'sunken into the plastic'

Any ideas.....please help my life depends on this.
