How do I handle clothes with poison oak on them?

I need to wash clothes with poison oak oil on them, should I wipe my washer with Tecnu after washing them? Some say to use cold water to rinse or hottest water, some say only detergent. What do you say?

Key is not washing contaminated clothes with other clothes, not overfilling the washer with clothes, using hottest water and longest time, using a high efficiency detergent and running an empty cycle to remove any residues in the washer.
