I am having trouble getting the cast clean with PPG DX330 wax and grease remover. The tractor was cleaned prior to mechanical work (now complete) oven cleaner and pressure washed 2 times. I have wire wheeled majority of tractor down to bare cast iron. After that I washed it down with Mean Green cleaner full strength, let soak for a few minutes, rinsed with water and blew dry, wiped same area 7 times with the DX 330 and clean rags and still getting a brownish color on rag. Out of desperation I took acetylene torch and hit the side of rear end (got it to about 110 degrees) with cutting oxygen on, allowed to cool and hit with DX330 and just a very slight coloring to the rag. Went back to the same area this morning and wiped again with DX330 and got more brown discoloration on rag, I think it was flash rust.
What else can I use or do. When I put the DX330 on I keep the area wet for about a minute and then wipe. Is there some other cleaner I can use prior to the DX330.
Humid and overcast here today, so I probably will not do much because of flash rust issue. I am planning to clean an area and then applying epoxy primer all in the same day as was suggested in prior post where I asked about it. Still unable to find a shop to do sheet metal, some indicated if I delivered the tractor to them, epoxy primed and scuffed they would take it from there. ( tractor chassis only)
Any help or tips on cleaning procedures would be appreciated.
