if the foam is original (ie more than 10 years old) I'd consider replacing it alltogether...it does degrade with time (the older stuff more than modern foams) and washing it might well destroy them...

otherwise, sunlight and fresh air are the best deodorants, so I'd just leave them outside for a week, and see if that helped.

washing any fabric does help, and I've found that the orange-oil based cleaners, maybe boosted with a dash of TSP (a degreaser) do a fairly good job of cutting that film on panelling, and the like.

any carpetting is going to be a pest as well (blech!) but shampooing it will help a lot :)

Febreze spray may help reduce the odors in the cushions.

There are fabric stores that sell foam rubber in various thicknesses that can be cut to fit for replacements.

Replace the foam ... it's not worth the effort to try to get decades fo ciggy smoke out of it.

Thanks, everyone. Dh will give them a shot with OilEater, in the pressure washer, leave them out in the sun, and if that doesn't work we'll replace them.

Otherwise, the trailer smells great, now. I painted every square inch after wiping with 409. DH put in a new floor and got all the appliances working again. We're almost ready to roll.
