Best way to clean up 34 years of grease and oil?

[meanwire]

What is the best way to clean up 34 years of grease and oil underneath my undercarriage? Trying to clean up the excess grease and oil, been using Oil Eater but taking forever. Didn't know if any of you could recommend some products or methods to clean up this mess. Thanks!

bring about $20 worth of quarters and head to the local coin-op car wash
bring a scrubber brush too

Take it on a deep snow run.

diesel truck facility with a pressure washer that is also a steam cleaner. and pay them 1 hour labor, they will have a shop clean up kid do it or something. thats what we do for customers.

Soak it with Simple Green, let it sit, power wash, repeat.

Look on the bright side...it's not rusting!! lol Steam cleaner works best..most car wash's have good pressure and heat and work good.

Oil Eater, Simple Green, Purple Power, etc. Let it soak, then use a pressure washer. Some guys will swear by Oven cleaner but I've never tried it. Degreaser and pressure washer seems to do the trick.

Catrol Super Clean or Oven Cleaner and a good pressure washer.

Scrape off all the thick stuff, and go to town with oven cleaner and a scrub brush. When your skin feels like it's going to melt, the oven cleaner is just starting to work on the grease... Don't let it dry on paint or you'll be repainting your rig... After oven cleaner I use plain old Dawn dish soap. Works like a champ.

Oh and wear some clothes you fully plan to throw away when your done.

again, if you take the grease off, it will rust...

I freakin coat my undercarraige with wd40 like 2x a year to slow the rust. If that was mine I'd maybe get a towel and wipe away most of it but at least leave a film...
Your choice though.

Scrape, then Purple power

 

[Ourobos]

Soda blasting

I agree, but if you do rid it of the grease be sure to fluid film the hell out of it.

Keep in mind that pressure washing or steam cleaning will blow some of the grit and moisture inside of seals where it will be out of sight but not out of mine.

Simple green straight, don't dilute it and a pressure washer.

 

[chuckinphx]

no pressure washer?? connect the hose to the hot side of the washing machine , degrease, hose off ---nossel will get hot!!! repeat, then youll have a mess to clean up in yard, carport, but it works..

Easy Off oven cleaner in the yellow can works very well
