Kerosene
While I'm a big fan of kerosene because it's an effective solvent that doesn't attack rubber, it doesn't offer the aluminum "brightening" characteristics of the other cleaners mentioned above.

It's water based and in my experience there was no evidence of corrosive potential. I only spray on and w@$# off in short order which works fine. I wouldn't soak parts in it. The use of petroleum distillates is prohibited in my state.

Really like the pic of the case after Green Magic. Super results!

I looked it up, though, and have to throw in a caveat if you use it, or Simple Green or the like. Green Magic has a pH of 12.7, meaning it is a strong alkaline cleaner. It's probably ok to spray on/w@$# off quickly, but alkaline solutions can turn aluminum black if left on too long. You really should clean aluminum with acid cleaners, but there aren't that many around. I had a really crudded-up FD and left it soaking in Simple Green too long. When I sprayed it off, the FD looked like it was anodized, but with streaks. Not good.

I recently used this on a number of items on my rig and it worked quite well on cleaning up areas that were covered in grease. I used it on the engine housing, gearbox, frame, and wheels.

A large can at Walmart is about $5.

I have not used the S100 engine cleaner but I have the S100 cleaner.

That stuff is wonderful. I plan on the engine cleaner since I saw it in their literature. I try to keep it all as reasonably clean as I can. Its going to age but like me (I quit my job did not retire) aging as gracefully as possible is important (some and some for me)
While I'm a big fan of kerosene because it's an effective solvent that doesn't attack rubber, it doesn't offer the aluminum "brightening" characteristics of the other cleaners mentioned above.
Like any petroleum solvent its also going to get on the ground. I am not a super tree huger but I try to keep it down as much as possible and with modern cleaners, you can do that.

I recently shifted my rifle cleaning to a non haz non odor cleaner and it works vastly better than any brute force cleaner out there, even the toxic ones. The new stuff is not just environmentally better, it works better. I even ran across some stuff that is as good as Tri Clorehtalane (yes spo) and I never thought I would see the day (and its a non hazardous stuff to boot)

Also, they don't evaporate completely so will work on rubber unless you use Simple green as an after fluhs (and why not just use that?). Theyu also attract dirt.

No it isn't, here's how I did it. :?

I recently cleaned the my engine using citrus degreaser and a tooth brush. Plus I had a spray bottle with water to rinse off the cleaned areas.

Here's what I've done with other sandcast aluminum engine cases - clean as necessary. Clean the case with a mild solvent after the first cleaning, then use brillo pads and aluminum spray pain to "scrub" paint into the pores of the engine. Result is a case that's easy to clean as grease and dirt don't lodge in the pores. Did that to my Type 247 BMW engine years ago and it cleans up with nearly no effort, no matter how dirty these days. Hope that helps.
