Spontanious Laundry?

A fire in London...

Fire investigators believe the blaze started accidentally in a hallway cupboard when the laundry stored there caught fire.

Charlie Pugsley, Head of Fire Investigation at the Brigade, said:
“Cotton laundry like aprons, tea towels and cloths can often be contaminated with organic cooking oils that can self-ignite if dried and stored.

“Make sure you do your wash at the right temperature with the appropriate detergent to remove any oil based contaminants. Also make sure you wait for your laundry to cool down before packing it away and store it in a well ventilated place.”

What? Dried organic cooking oil can self combust?
Does anyone besides the CIA, KGB and MI6, know what kind of oil can do that?
