What is the best in your opinion? Ive used GUNK for years but just dont seem to be working. THANKS

 

How heavy of a grease build up are you trying to remove?

I've used Simple Green at full strength right out of the bottle and had good
luck with it in the past. Just be careful when using it on/around bare aluminum.

 

Greased Lightning
Simple Green
Purple Power

On the aerosol side, Gunk Engine Degreaser Gel

 

Castrol Super Clean. Comes in a purple spray bottle. Love that stuff. I put that ***** on everything. LOL (Just kiddin!)

 

bought a 77 a couple weeks ago,just want old oil,transfer case,axles cleaned up. Im pretty fussy. THANKS.

 

I've had some pretty good luck with Johnsen's foaming degreaser and simple green.

 

When things are really greasy, I spray brake cleaner on the part, then use Simple Green full strength.

 

$1 store. oven cleaner.
gear up tho

 

I bet that will work,thanks all.

 

x2 on oven cleaner, cheap and works good.

 

If you don't care about your paint, oven cleaner is your best bet. I'm currently cleaning up a 5L oil spill on my aggregate driveway and oven cleaner is literally the only product that actually works. I use it on pretty well anything if the paint isn't a concern.

If you want to keep your paint, gently scrape off any big chunks you can then use engine degreaser with a pressure washer.

 

a steamer,melts away

 

I used to use GUNK but it is not as effective now. Simple Green seems to work as well as anything. Hot water or steam helps a lot also.

 

Here is some more ideas....

Gasoline actually works and is cheaper than anything else I've tried.

Any other petroleum based solvent is great as well; Mineral spirits works well, but is about 4x the price of gasoline. It isn't as volatile, so it wets an area longer.

I've tried all the colored cleaners and they dont seem to do much more than plain water for me.

A siphon sprayer is a great way to apply whatever you decide, without wasting a bunch of it and doubles as an air gun to help clean it all off after.

Here's a cheap one:
You can also get 'em with long nozzles to help get into small areas.
