Need to clean an aluminum part of baked on grease.

Have tried two Cascade pods in the dishwasher unsuccessfully.

Now have a spray can of EasyOFF oven cleaner.

Is there any thing better?

What steps are best with the EasyOff?

Easy Off contains lye if I remember right, and lye will eat aluminum if left on for too long. Might be fine on big pieces, but not so good on smaller fragile items. Probably best to be cautious if doing that. Oh, the lemon scented stuff works quite well for removing paint on inside woodwork, fwiw. I have heard (haven't tried it yet) that small aluminum parts can be successfully cleaned by heating them for a day in a crock pot using ethylene glycol antifreeze. I wouldn't try that in the house, but it might be ok if done in a garage where there is lots of ventilation.

I've been surprised at how effective these products are when others have failed.

I regularly clean deep fryer parts. Most stuff is stainless so I have an acid bath and aluminum DOES NOT like it. So for aluminum parts I drop it in a pot of boiling water with a box of baking soda added. This works ok, but not great. With such a large part I can see you might have a problem with this method. Also, the older the baked on grease the harder it is to remove.

Other than that I have no idea what might work. Definitely NOT EasyOff !!

Depending on the part, you might try finding a place that blasts with dry ice - usually fire restoration shops do this or know who does.

Formula 88 is said to remove carbon from pistons when they are soaked in it overnight too. Just one more thing I've been meaning to try.

Never before heard of Formula 88.

Years ago i tried soaking some used 1994 Magnum 5.9 pistons taken out of service in 1998 that had heavy carbon deposits. I used Techron, Regane, Seafoam, LubroMoly Jectron, ATF+2, Marvel Mystery Oil, Mobil One 5W-30, Castrol Superclean.

Techron did best,
but even after a week long soak carbon deposits remained.

When I clean my things we cannot mention here and I'm not talking about Big John, I use WD40 as the initial carbon cleaner (only thing is't decent at). It doesn't do so well on baked on grease though a steam cleaner would.

Try LA's Totally Awesome from the Dollar Tree. It's harsh on the lungs, but removes all kinds of crud. Test a spot first. Used it on the rims of our 2008 Town and Country before we traded it in. They were clean, but not sure what long term effects it will have on it.

I do have some of LA Awesome cleaner and tried some on this baked on grease. It seemed to slowly dissolve a thin film. Maybe if i could find the right container for a long term soak.

maybe try a wallpaper steamer or one to get wrinkles out clothing.
heat it up with steam then apply degreaser to remove.

I just went through this on a nasty bellhousing. Easy off worked like a champ but rinse it off with detergent really good or it will acid stain it.

What is the part? Do you have a picture.

I don't think I've ever come across something I could not clean with elbow grease and typical solvent or water based cleaners.

EasyOff did a pretty good job of getting 80% of the carbonized grease off the flat surfaces.

I let the EasyOff sit on the dirty aluminum metal about 20 minutes,
then scrubbed with a brass wire brush.
There was some strong base chemical surface etching afterwards.

A flapper sandpaper disk on a
Dremel style Milwaukee M12 rotary tool
then got some of the tight corners clean,
but the disc worn down quickly in about twenty square inches of polishing.

I still have some carbonized grease streaks along edges.

I might get some Formula 88 for overnight soaking.
