You might try FIT's lye gravy. He does a little demonstration on his website and he hangs out in the case descution a bit so you might catch him there and ask a question or two. His stuff is easy and cheap plus there is no scrapping or work!! Plus he also give a good electrolisis demo to with instructions. Its all under the restoration tips.

Will the lye gravy stop at the grease or will it eat the paint off too?

It's not the Lutefisk that works, but rather all the neighborhood Norwegians that show up to lick it clean! Just be sure not to use too much Lutefisk, or you will have to beat the Norskies away with a axe handle.

When you hear what Ole (not that Spaniard guy, ' either) was just up to, you might want to beat him off with an axe handle! Makes me think that some of those stories about the two of you are TRUE!

Seems I've spent most of my adult life scraping grease off old iron. Now, there is grease, and then there is the OLD HARDENED GREASE which I think you are referring to. If you've got a few extra dollars, you can hire an "on-site" industrial power washer guy to show up. He's got the unit with superheated and super-pressurized water and steam and detergent that'll clean barnacles off the Titanic, but it won't be cheap. The other solution is to scrape it off by hand, not fun but it's gotta come off. Afterwards, you can use any of the methods others below have suggested for what's left. The only tool to use is two of what we used to call "lino" knives. That's the knife with the thin, hook-shaped blade with a big round curved handle that you can get a real grip on. Leave one as it is (with the point as it left the factory) and round the point off somewhat on the second one with your bench grinder. That's all you need, no hard grease will stand a chance. Wear a glove, not for the mess but to eliminate the skinned knuckles.

Here is a picture of our equipment. We are set up to do more industrial and commercial type work. And We've done a few tractors over the years beside mine! :-)

I'll send my dad up there. If there is grease or dirt on a tractor he can't resist not pulling out hs "grease scraping knife" and working on it. Ya don't have to ask him, he'll do it all on his own!:) If you have a industrail supply store handy there is some stuff called sc900 I believe that is made by Spaartan Chemical Company that will cut through anything. Spray it on and let it soak for about minutes then wash it off. We use if for forklifts and when we have to tear down a punch press.I have seeen it take grease and paint off that was 15-20 yrs old like it was just put on there.

oven cleaner is good and it sprays on easy and washes off clean. drano is brushed or mopped on and is somewhat messy, but it cleans better than oven cleaner. just be careful of either.

I've had excellent luck with Castrol Super Clean. I buy it in gallon jugs and put it in a spray bottle. It seems to work best if you don't wet the surface first. Spray it on full strength and wash off with a pressure washer or hose after letting it soak. For really heavy stuff keep soaking it down as it soaks in. It will take paint off of anything that has had grease or oil on it.

Castrol Super Clean is also biodegradable. The directions say, as you stated, "use on Cold, Dry engine."

I have a pressure washer and steam cleaner that I use on the farm to clean stuff. But at the Wayne mentioned, Oven cleaner is a good cleaner to use to clean off grease. And a cheap place to buy it is one of those dollar general stores if you have one in your area. Word of caution, use the oven cleaner down wind of you and anything you care about. IT is strong stuff that will burn your eyes and skin. And it is not good on any nice painted items, like a vehicle parked nearby. I learned this from the road of hard knocks :>(

Also another thing I have done is go to a quarter car wash. I have pulled tractors in on trailer and just leave them on the trailer and use the engine cleaner cycle. Better yet, spray a thick layer of engine cleaner on the spot before you head to the car wash and it can be working for you while traveling to the car wash. Never have tried using diesel on hard grease. Sounds like it would work good if you could spray it on a few days before and let it soak in and soften everything up. Learned something new tonight. Thanks Wayne and Larry for the reply's. And Norske that was a good question that helped all of us learn something new.

Happy New Year!

Working on old BE and Northwest cranes like we do we see more grease than you can imagine. Like Larry said the best thing we have found is oven cleaner. If you can get the main part of the grease scrapped or dug away and spray the oven cleaner on it and give it a chance to set for a while before rinsing you'll see pretty good results. If you have a "Hotsy" to go along with it that makes things even better. Something else that we've found works decent is called Grease Gone. It's better on the softer stuff, but like everything else, give it a chance to soak in along with a couple repeat soakings and it'll do OK on any of it. If anybody else has knows of anything better, please post. These old cranes we work on are always nasty so we're always looking for something better.
