Notes on Pressure Washing Frames
Pressure washers appear to drive the water through whatever contaminants are embedded in porous materials, and the water on coming out drives those materials back out of the pores. It is effective against grease and oil, and to a limited degree can take off surface scale.
Water, however, is NOT an abrasive - and so there is a significant amount of rust left on the frame afterward.
As a test case, I used a 2400 PSI unit on my 82 F-100. Areas heavily soiled by grease were moderately well cleaned, although there was a layer of oil film left behind. Some surface rust was removed, and old paint that was flaking.
But it will not do the whole job by itself.
As a prep method to keep a sand blast unit from getting it's beads trshed by oil intrusion I would recommend it. But for a home hobbiest I would say stick with the wire wheel and a lot of patience.
There will still be surface rust after the process, and a certain amount of oil as well.
The oil at that point may be cleanable using Engine De-greaser.

Notes on Pressure Washing Frames
I have been searching for a way to do the frame of my 68 F100 and sandblasting is ok if you are doing an off frame restore, but I am not and decided to look for an alternative. Found Eastwood unique automotive tools and supplies has something called a rust encapsulator. Sells by the quart, pint or 16oz spray. I thought I would hit the rust with a wire brush, pressure wash what I brushed off, then coat it with the rust encapsulator. Anyone tried this stuff before that can say if it is a good product? Thanks

A lot of people swear by the POR-15 products.

When i was restoring my 1979 F-250 frame i scraped the thick grime off, then i pressure washed it with an electric pressure washer that i have, then i wire wheeled it with an electric drill. When the frame was thoroughly cleaned i used The Eastwood Company's "Full Chassis Restoration kit." The kit cost $60 and it comes complete with 2pints or brush on Coroless primer, and 4 aerosel cans of Chassic Black. This kit was one of the best things i bought, and it saved alot of money. Very very little preporation to use this product, no sandblasting required. All you have to do is wire brush or wheel all of the thick, flacky rust off and apply the primer. Good Luck!

Notes on Pressure Washing Frames
Just finished pressure washing my 56 project truck. Wow...I like that. I could reach everyplace but the underside which I will have to work with a wire brush on a drill. The top and sides are pretty clean. I am ready to use a wire brush on some misc rust....clean with some acetone and then use some paint or por.....Try it, you'll like it.
