I grew impatient when searching old threads so decided to ask the question….

anyone have any engine bay/belly cleaning tips and especially PRODUCT recommendations?

I’ve got Jurassic period oil grime crust on my block and belly. Any magic in a bottle out there? Or is this still simply a game of wearing throw away clothes and laying under it with a power washer in hand?

how about gunk gel and foam? Any others?

thanks, J

Heres a couple of videos that may help:

Warm the engine and spray the whole thing with a bottle of Simple Green. Let it sit for a half hour or so, get your regular garden sprayer and hose it off, except the carb throat, distributor cap, or directly into the alternator. You can cover those with foil or plastic wrap. Be amazed.

For light oil film, DAWN dish detergent works good.

My favorite go to is Gunk.

I've had good success with Purple Power diluted 1:1, sprayed on in 2-3 "coats" over 5 minutes or so, left on for 15-20 minutes and washed off with my pressure washer.

What Woodchuck said. Used this when I re-gasketed the engine in my 66FB. Used a stiff brush for the really hard caked grease and grime. It works.

Simple Green soaking overnight. Cold engine. Wear a mask when spraying, particularly if misting. May have to use elbow grease to let it penetrate the caked-on stuff and get the out of the way places.

Don't breathe it. It'll clean your lungs too.

Same for trunks also?

I've actually had good luck with the O'Reilly house-brand foaming cleaner, the one that looks like shaving cream.

Have used it on every hill-billy engine rebuild I've ever done, no experience with the motor in the car unfortunately AND I cover that ×%$# I mean.... I. COVER. THAT. *&%$#. 😆

It'll look like the Stay Puft Marshmallow Man banged your block 😆😅🤣

Watch the Simple Green around aluminum!
Get the aircraft Simple Green if you want to play it safe.

Avoid simplegreen if you have aluminum parts as it'll corrode them pretty quickly.

I have switched to Spray Nine for almost all my automotive cleaning needs. Spray it on, wait a few minutes, scrub it in, rinse it off.

I use P21s - https://www.amazon.com/gp/product/B0002LBKCE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

About a year ago I had coolant spray all over my engine and throughout the engine bay. Literally spray it on a cold engine, wait a few minutes and wash it off with a hose. I always cover my alternator, carb and distributor. Then I use a leaf blower or air compressor to dry and a towel to wipe down my valve covers and such. Works wonders

 

[Clay_in_ABQ]

Dawn also makes a degreaser, sold at Lowes, etc. Spray on, brush, rinse. In short, there are a lot of options. The important thing is to keep your distributor, carb and alternator dry. Cover them with a plastic grocery bag or trash bag.

Good stuff. Thank you all!

Now that’s a funny mental image!
