Hello
I got this old EF-3 and the rake is rusted solid!
Tried the PB blaster, wire brush, and wiggling with the vice grips and blasting out dirt with the compressor while vacuuming. I got the rake to move 1/8" and now 1/4" back and forth after 3 days of soaking and wiggling.
Now the problem seems to be all the corrosion on the heat tubes. I can easily get that rust and corrosion I can see on the bottom of the tubes with the wire wheel on the drill driver bit not the top of the tubes. The top row is especially difficult. Any ideas?
