Keep it clean? I am really scratching my head on how to clean the undercarriage on my Z. Any suggestions? It doesn't help it is lowered also. I won't go through one of those automatic washes that sprays up from underneath for obvious reasons. The only thing I can think of is to find a shop that would let you power wash/clean it while up on a lift. Just wondering what all of you that don't have their own lift in their garage do....

A set of Race Ramps combined with a good set of high quality/high lift jack stands should allow you enough room to get under the car for cleaning. You really don't need to get fully underneath, just enough clearance to reach under and clean/detail. The Race Ramps alone provide enough lift where you could get about 80% of it cleaned and then jack up the rear for the remaining 20%.

During my annual wheel pull, polish and clean, I check out the undercarriage and make sure there is no damage, fluid leaks, or other issues. I then do a quick cleaning. Nothing real OCD, but just enough to make me feel better. My OCD will kick in the day I install a 4-post lift.

The biggest thing for me in keeping it clean is not driving it in the rain or other adverse road conditions. However, each time I wash the car, I use my floor jack and jack stands to lift the car and then I get under the car for some detailing.

I also have used a self service car wash with the wand sprayer to clean the underside.

I have never tried this, but have heard of others doing this- pulling a lawn sprinkler underneath their car. The water pressure would not be as high as a car wash, but it might actually work if you have good water pressure and you are thorough. Salt being water soluble- might not need anything more than a good fresh water soaking to remove it.

I have a touchless car wash for 7 bucks that sprays underneath the car and the wheels that cleans the red calipers. i do this once a year. Harmless to the car and easy on me. Great results.

That's actually so silly it might just work


I have a set of 10" race ramps (67" two-piece) and my step-mom got me a set of 12" race ramps wheel cribs for Christmas. Should be perfect for getting under there to clean for the first time

Who cares if the bottom is dirty. So long as the top is shiny!
That only applies to cars, not women.

Also, Once a year I first raise my front up on home made ramps, hook up my sprayer with Dawn soap inside, attached the sprayer to the hose and wash. Let the soap sit for about a hour then wash off. Do the same with the rear. Works for me.

I do mine every winter, not very dirty as I only put 600-700 miles a summer on it, and no rain for me.

Here is the method I've been using for 20 plus years to keep all my cars clean, especially the show cars and my Z. Find a good source of hot water. You can either install a brass tee onto your washers hot water line or hook directly into your hot water heaters drain. Attach a good hot water hose or garden hose if it's decent quality to either source. Pre rinse the undercarriage to get most of the loose stuff and grime off. Get a good sized spray bottle and fill with 1 cup of Simple Green, 1/4 cup Dawn dish soap and hot water. Spray down everything. Wait 20 minutes and rinse again with hot water. If you have any stubborn grease spots use full strength SG and a brush. I've kept undercarriages looking new with this method.

It’s a constant battle to keep clean. I did find that Chadwick’s no sling tire dressing works really good on the wheel wells and other stuff.

LOL, I would have to agree about the women part anyway!
