    Just thinking how lucky the OP is.... Central FLA, no salt, brine, ice or sand to slowly eat away your Jeep! A little Florida mud adds character!

    That's so funny! My husband and I literally talked about this yesterday:like:. My main concern was just removing the brine, so this should work excellently.

    From what I've read, the only concern to be had from power washing a vehicle is too much pressure. Anything above about 2000psi could possibly damage paint above or oil/grease seals and wire harness connectors below. Anything much less would defeat the point of wanting more pressure than a good nozel on a garden hose.

    Earlier this year, I picked up a Karcher k5 premium and a bunch of different attachments, including the "under bits" sprayer pictured above. It's been great and I highly recommend it to anyone looking for a quality built unit that doesn't break the bank.

    Regarding getting kids to wash vehicles or mow lawns...YOUR area has a last-census average home value of $809K with an average income of $91.5K - mine on the other hand has a $196K average home value with an average income of $54.6K. I can't imagine living in a "less affluent neighborhood" in CA! And I can't imagine what it would cost to have a kid wash or mow in YOUR neighborhood! LOL. Thanks for the chuckle though...(got any kids who want to go about three hours away to wash vehicles or mow lawns?)

    "Lightly" heck try abusively!!!
    I have had a pressure washer from the local car wash so far up that underside many times. Same goes for the engine bay. I'll pop the hood and blast the underside of the hood, all over every nook and cranny in the engine bay (the only thing to avoid is the intake) and then crawl up underneath and blast away from front to rear bumper. You don't need to worry, we've had it in water up to the bottom of the headlights (that's after a 2.5" lift) and have had no problems. I'l shove it through the rims right onto the caliper where the pads meet the rotors to get any dirt out of there too. Blast away!!

    I have the Ryobi one from Home Depot, they work great has 3 nozzles so it lowers the flow rate thru each nozzle, hence it isnt going to harm anything underneath. I have a 3100 PSI gas pressure washer, and no means to dampen the pressure/flow but the ryobi unit splits the pressure to the 3 nozzles hence not to harsh.

    Per kids doing anything, wouldnt trust them washing any of my cars, unless you like swirls.
    Only time I see any kids washing cars is usually at fund raisers by the HS Cheerleaders, went by a few weeks back in center of town, in my pristine SRT and the gals are waving me to come in to have some dirty water and soiled rags to buff some swirls into my Mango paint. No thanks dear go practice on Daddy's black BMW ;)

    Agree any of the younger folks seem to be not too interested in cars (unless mommy and daddy give them one) and cleaning or doing car maintenance is work to be avoided at all costs.

    And no, that isnt my mansion, lifted that from the Ryobi ad on HD. can get these in the pressure washer area for like 40$

    We live by a beach in Australia , after each run we use our garden sprinkler on full bore for 20-30 mins slowly moving it under the vehicle front to back . Works a treat ...
