Clean Undercarriage

This has been somthing I've always wondered. How does everyone especially dealerships clean the undercarriage. And make it look so nice?

 

I’m not sure if you’re looking for a detail job or not but typically when my wife and I go off roading, especially in some pretty bad mud, we put a sprinkler underneath the vehicle and move it from front to back about every 20 minutes. All of that water spraying around helps break up some of the mud that gets caught underneath.

 

Dealerships run their vehicles through the local 'swirl-o-matic' car wash and get the undercarriage cleaning. A more practical way is using an attachment for your pressure washer, or one of these:
