Finally got lucky and found a bouncy seat at the local Pick n Pull yesterday. Perfect timing as I'm about midway through a cosmetic refreshing of my '89 Raider. New paint, custom rack, wheels/tires, mirrors, lights, recovering seats etc. My question is, the bouncy seat frame is disgustingly filthy, greasy with dust and dirt caked on along with the usual rusty spots. The best option my buddy and I can find to get this thing really cleaned and degreased so I can work on the rust and then repaint is to power wash the thing either using a home unit or take it to a do it yourself car wash and blast it clean. Any thoughts or concerns about using pressured water to clean this frame?

Thanks a bunch for any help you can provide.
