How do I clean the underside of a vehicle?

[joemck]

I have a 2015 Ram lifted 6in on 37s and hate the way it looks underneath. I have tried pressure washing but that only seem to get the surface dirt off. Do you have any advice on a product or method of cleaning the underside of a truck? It is mostly dirt and grime. No mud or oil.

Pre-rinse with a pressure washer. I’d look into using a foam gun or cannon with a strong APC or degreasers and let the solution dwell on the undercarriage. I’d also look at getting a dedicated wash brush(s) for just using on your undercarriage and agitate the wash solution with the brushes.

+1. You need some muscle. You have enough room to roll your self under there spray it down give it a good scrub then pressure wash it off. I would grab some Optimum Power Clean. It's pricey but IMO it's the best APC out there. It's strong but it's one of the safest one's around. If you have a hard time rinsing I learned a trick a while ago. Hook up a garden fan sprinkler and just drive back and forth and let it rinse the under carriage. Use a leaf blower to dry once it's done draining out. After your done. I here Fluid Film Lube works wonders on under carriages and metals to keep them from rusting and looking nice.

I’ve heard CGs Bare Bones is good for stuff like that, but if Fluid Film works that would be a bonus.

Fluid film works great to protect and prevent the undercarriage from rusting however if you care about having a clean looking undercarriage I would not use fluid film because it does not easily wash off and dirt will stick to it.....

I love fluid film and use it on my vehicles because I do not want them Rusting however I do not get underneath and clean my cars I just rinse with a garden hose and apply more fluid film

Thanks guys for the advice. I am going to try the Optimum Power Clean that inDetail suggested along with some good ole elbow grease. I am also going to try the Fluid Film for my other projects.....

Amazing Roll Off works very well also.

Isn't the Fluid Film quite visible? It not clear correct? Just wonder how good it actually looks on a truck that is lifted and the underside is all exposed.

Hello,

There is a product I bought from Menards called Blaster heavy duty corrosion stop. I used this on the suspension parts and fluid film on the frame. I have only driven my truck in the snow one time but my suspension still looks new since I sprayed it on last in November of 2016.

As a non-truck owner I'm curious about the viability of trying to keep the underbody and suspension of a lifted truck looking really clean.

On a couple occasions I've cleaned out the wheel wells of my car and SUV, but even in dry conditions they are dusty and dirty within a day or two of on-road use. If it rains or snows, they are dirty in minutes. Isn't trying to keep the visible underbody bits spotless on daily driven lifted truck a losing battle?
