Cleaning the bay after mudding/off roading

Hey guys,

Went off-roading for the first time yesterday with PGH Off-Road and had a blast but now the day after...

I have a bit of an overheating issue because of the mud in the radiators, but I know how to over come that. My question really centers around the electrical connections in the engine bay. I've been told to use electrical cleaner to clean each of the connections, anyone done this/know if its safe?

When I start it up as well, it starts fine, but it sounds quite muffled and not as lively as it used to start up. The battery is fine, fuses are fine, anyone have a suggestion?

Also important (but less so), the horn is particularly weaker now that it went through mud (unsurprisingly), but I wanted to see if anyone has ever successfully cleaned it out to full strength.

Cliff notes for the ADHD challenged (me):
-safe to use electrical cleaner on a jk?
-starter is weak but works
-horn got mud in it, barely works, suggestions?



For a stock, non-lifted Sahara still on the factory bridgestones, she held up AMAZING. She crossed TWO rivers, got me through two rocks with about 1" on each side while going up a hill like it was nothing. I was blown away by its performance, she took everything I could throw at her and kept up with lifted rigs of all sorts with big tires and tons of upgrades.

But before I think about upgrades, I want to get her running strong again. If I've learned anything about cars - maintenance is paramount.

Simple green and a garden hose. No need for electrical cleaner. The only item under the hood I dont directly spray is the battery itself.

I had the same problem with the horn a couple of weeks ago after some good mudding.
I replaced it this weekend.
I also turned it downward, my theory is that yes, water will get in but it will drain out. With it turned upward, like from the factory, it will trap water inside.
I've used this technique with other vehicles with success for 30 years but I'm sure someone will chime in and explain to you how stupid my idea is.

A good electrical cleaner is WD-40. It was originally developed (for NASA I think) as a water dispersant, hence the name.

Hey DesertJK, It was good meeting you yesterday! Hope to see you out on the trails again.
My airbag light keeps coming on and off now from yesterday. It's amazing what these vehicles can do stock.

Great meeting you too! I can't wait to come back with some upgrades! Funny how of all the things that could go off, an airbag light would be one of the things I'd expect the least lol

Cool, thanks! But what year is yours? Mines an '07 and the horn was already facing down

I've always been a firm beliver in dielectric grease in all my vehicles. 4x4, motocycle, boat, hot rod etc.

Pack every single electrical plug you can find with DG and make sure the locking tabs close all the way. Includes spark plug boots.

I found 3 connections in my JK that were not clipped down from the factory.
Door, foglights, and some sensor thing on the passenger side.

Dielectric grease keeps water out of your connections and prevents corrosion which leads to failure.

When you go to spraying the engine with the hose, is it bad to use a power washing hose? The bay that I wash is use a relatively strong pressure washing hose, and I dont want to rip any wires loose, or crap like that.
