Best baked on oily dirt remover?

[DBoyd]

I finally pulled the hood off the 1949 "R" JD last week and discovered it is filthy under there. Years of built up greasy dirt baked on by dry hot temps and I want it OFF!! I don't have access to a pressure washer or steamer. That would be too easy. I've been scraping the worst of it off and now I need something to spray on or brush on the tough and inaccessible places that would remove the crud.

I've used a can or two of Gunk Heavy Duty Gel and this built up crud just shrugged it off with little to no results.

Any suggestions???

Thanks

Don

Mineral spirits in a spray bottle works well, just dont let the tree huggers see ya :-laf :-laf

That's basically what is used in parts washers, although I'm pretty sure they have some eco friendly stuff available too now days.

I was thinking about trying that with plenty of rags and a solvent brush.
Thanks for the suggestion.

Yep, that's what I have to use on my old 1950 B F Avery R/MM BF tractor. I have tried my 4,000 psi pressure washer using a degreasing soap and it won't knock it off either unless I soak it with liberal doses of mineral spirits. Letting it soak for hours before blasting it with the pressure washer helps too, but avoid the distributor or magneto, starter, and generator if equipped. Some areas such as around the cylinder head/exhaust manifold will require a wire brush.

I use parts washer fluid from Tractor supply in my parts washer. It's some kind of petroleum based mineral spirits solvent. It's hard on the pump, but works much better than that eco-friendly water based stuff.

If Castle products are available in your area get aerosol cans of Shop Solve. The stuff is incredible. Use it for the areas that you are having trouble with.



My techs outright refuse to use anything else.



Local car and truck dealers will know if a Castle peddler is in the area.

I'll check on line too for Castle products.
I also picked up a jug of mineral spirits today.
Something's gotta work.
Thanks.

DBoyd,
The red can spray "Brake Klean" works real well. The "new" green can stuff does not work worth a *****. Gota work fast depending on how much you spray because it air dries fairly quickly.

If you're desperate, try ordinary liquid or gel paint remover.

Conventional oven cleaner works well too if you don't care about the paint.

Why don't you just give up and give that Model "R" to me. . I love that tractor!!

Diesel fuel with a stiff bristle plastic brush( Not a wire brush) works good too.

Regardless of what you use, you are in for some elbow grease.

If one was real desperate, I'd use a sand blaster with either glass bead, or plastic shot.

Dawn liquid dishwashing soap, undiluted, poured all over the stuff, and let it soak. Read about that in an 8n tractor restoration book.
