What is your preferred method of removing 70+ years of greasy, oily, muddy crud from engines, axle housings, steering boxes, drag links, transmissions, transfer cases, etc... to get ready for paint? I've tried sandblasting, pressure washing, wire wheels, screwdrivers, etc... I'm working on some stuff today that my pressure washer just wont touch. And the sandblaster seems to be taking forever as well.
My process is to start with a pressure wash first, then use a 1" wood chisel, followed by sandblasting, or wire wheel. What are your methods? Here is what I'm talking about, this is after the pressure washer. I wonder how a hot water pressure washer would work? |

I've had luck with parts like your showing by dipping a wire brush in kerosene and just scrubbing away, then wash it down and dry it, followed by paint usually. I only do this in open air for obvious reasons
The chisel looks good for big ideas but the gas and brush help brake up stuff in small or weird areas

I've heard one of those really hot steam pressure washers will blast it away amazingly.
I don't have one of those so I do a manual scrape with a putty knife and wire brush, then hose it down with degreaser, let it sit and eat on it for a bit, then pressure wash it off as best you can. For detail work I put a wire wheel on a drill and go to town, then throw the wire wheel away when it becomes hopelessly clogged with clay from 40 years ago.

See if your local rental center has a steam cleaner. If that's a dead end buy a few cans of over cleaner (EZ Off) and let that soak in for a bit followed by the pressure washer. Might take multiple efforts; good luck.

paint scraper/wire brush/chisel, then a tooth brush and can of mineral spirits. Finish with grease and wax remover if you're going to paint it.

I'm in the process of that method myself right now on another drivetrain. I've been at it for a few months now but I think I'm doing it wrong, I think my dry ice is too wet.... Edited by Scratch - 05 Mar. 2022 at 11:12am |

Think that engine is stuck yet ?
Years ago I rented a steam cleaner to clean up under the hood and the frame on an old truck we were going to paint. It did an amazing job, came out squeaky clean.

If you can't get there in a Jeep you don't need to be there!

Please, please, please: Never use gasoline to clean parts! That's a very dangerous recommendation.

I too used these methods. Very tedious.
Try a air needle gun scaler. I just bought a compact one and plan to try it out this week. If as you describe the built up crud is hardened grease & dirt I’ve heard about and saw video of a fellow using one to clean up a transmission. Prices are very diverse. I picked up one at horrible freight for $29. Edited by Fred46 - 30 Apr. 2022 at 9:30am |

I haven’t done a part that big yet but so far I have used solvent, pressure washer, Purple Power, pressure washer, solvent, wire brush on the transmission and transfer case. I am down to the concrete like dried dirt. I have been using scotchbright wheels on the dremel to get the tight places and the discs on the die grinder to finish up. I would just get the parts hot tanked if there was one conveniently located for me.
I used Easy-Off oven cleaner on a block once. It worked well but burned when it splashed on me when I hit it with the pressure washer. Not too bad on the arms and hands but the drop that landed on my lip got my attention. I am very glad I was wearing my sunglasses.

This may or may not help you but it’s worth a try. A couple years ago I installed a garden hose faucet plumbed to the HOT water system in the house (next to the existing cold faucets). It is really helpful for what you describe (it doesn’t hurt to temporarily crank up the temperature on your water heater either). I have not tried it with a pressure washer but I certainly see no reason that it wouldn’t work. Of course you only have 50 gallons of hot water at one time but I do what I can and then work on something else for awhile.

Yeah, that stuff is really caked on and hard to remove. A steam cleaner is the best bet and will do a good job.
If a steam cleaner isnt available spray can degreaser from the LPS does a good job if its left to soak and the hit with a pressure washer. Took me a few times but got it all blasted off. Hot water faucet thru a pressure washer helps alot.
