The NW is getting a bit dirty underneath and I've been thinking about one of those high pressure sprayers to get rid of the red clay that is sticking under there. Anyone had any experience with these sprayers or have a better solution.

thanks

I use a high pressure cleaner on my vehicle whenever I give it a clean - probably not often enough !! If you intend to actually get underneath it with one, put your cosi on and be prepared to come out looking like a drowned rat. It does a pretty good job on removing most stuff from underneath - might have to wet it all and let if soak for a while first.

Enjoy

Underside of my Paj gets a spray fairly frequently. Fortuantely nothing has the time to build so i don't have to go nutso and blast crud away.

If you do need to remove lots of builtup stuff, it may take a few attemps to get it wet enough to dislodge. Don't concentrate too much in one spot for any length of time and only go to a narrow spray if you really need it.

Don't aim a narrow beam at anything 'fragile' or critical, like plugs/connectors or seals if you can avoid it...


The red dirt up here is horrid if you let it get on/in your vehicle when wet and let it dry... nasty, nasty stuff to try get off!

I give mine a spray with a high Kartcher or the hose , depends on what I use, then a spray with CT-18 in a garden sprayer, leave it while I wash the rest of the car, then give it another spray with the Kartcher or hose. I have sometimes then given another spray with CT-18 if it is going to rain in the next couple of days to rinse off when driving.
Cheers,
Andrew.

I use one of these on my garden hose.

Pressure washer is too high a pressure under a vehicle for my mind; too easy to blow past seals etc.

don't forget to check the voids behind the front mudflaps, lots of dirt/dust and sand loves to accumulate there if you don't get the hose in there.

I used to go to a car wash that does the underside of your vehicle with a high pressure wash. Haven't seen one in years but it was good while it lasted.

Thats all well and good, but......

I am known to be fairly fastidious when I clean my vehicles (including the past race cars). I thought I had done a fairly good job at getting the Border Track mud from under the car, but on the weekend when doing a tyre rotation - it's everywhere!!!!!!!!:eek: between the fuel tank and the plastic guard, inside the control arms, on top of the diffs, in every gap behind the hubs, in the vents of the disc rotors, etc, etc

The best way to clean under the car normally is to park your car on the lawn (if you have some) and put a rotary type sprinkler under the car and turn it on flat out!!!! Leave it on for about 10 minutes then shift a little bit at a time. Should clean most of the underneath. I did not do this for the last trip as I didn't think it would be that bad as it wasn't that muddy, it will be done after every trip from now on though!!!!!!!!!!

Great idea foxy. Also if using a high Presure washer be careful around your intercooler, even the hose can damage thoses fins.

A liberal spray of WD before you go can assist in the dirt coming off easier on your return.

Used the Karcher on Sunday myself to remove half a ton of mud under the NS-y after extracting a mates new 200 Series which he buried up to the dif !
Wasn't in 4WD apparantly ...... too many buttons & knobs, flashing lights etc !
(Hope he's reading the manual this week ! )
I'm pretty sure I got "most" off, but will do again this weekend, With CT Truckwash.
Major issue is the cow dung flung around during the recovery.!
That stuff sets like glue !.

I don't know what else you could do to clean the underside really ???
A few years back after a thorough clean from a Lake Eyre, Arkaroola, Flinders trip I parked the Paj out in the shop carpark (on a rainy day) and when I came back out in the arvo there was a red haze all round the car from still more Lake Eyre dirt on its way out !
Nothing wrong with that !

If that's what he told you, then he's making it up!! those machines are constant 4WD and only have a high / low range and centre diff lock for choice. :nana[1]:

On the subject of a clean Paj arse :lol9[1]:.....

Does anyone use any kind of anti-corrosion products say, inside the chassis rails or as a general spray over the underbody and components?

Was thinking of getting under there with a can of Inox w/Lanolin (leaves a little bit of a coating) just to give it a bit of added protection- especially now that she gets a bit of extra salt up here being close to the coast and dropping the boat in the water.

Something thast easy to apply (spray probably) and lasts a little while would be good. Open to suggestions!

Ive got an ALTO pressure washer. It has an adjustable nozzle that turns from straight to 90 degrees. So you don't need to change fittings during the clean. It appears to be the only one around with that option. ALTO are not in bussiness anymore sadly. Especially as mine is in the process of packing it in! It has a pressure valve to stop too higher mains pressure coming into the unit...go figure? that valve has always been a bit dicky and now it has shut down the machine. I could normally crimp the mains hose and it would restart. Anyways, that attachment is the ducks nuts for shifting mud from under the car to cleaning the roof ( Set at 45 degrees )

Speaking of underbody clean and prep, anyone used the underbody washer at rainbow beach if it is still there. Used it when I came off Fraser back in 2003. Its a drive on pressure cleaner and sprays an oil and water mixture under the vehicle. I never had any dramas later mechanically, it was an 01 hilux. It buffered the vehicle it was so powerful! The idea was to use it going over to the island and then again on your return.

Cheers Matt.

Well as a foot note, the alto just fired back into life. It shifted a bucket load of crap from under the Paj! It didnt work without a hitch, but its still going.

Got stuck into a few of the "not so often cleaned" places today.
Mostly concentrated on the inside rims- took a while!

Lots of scrubbing. Spent nearly as long in the shower afterwards, I was coated head to toe in crud. Suppose thats what happens when you lie underneath the car with the hose and some rags and brushes!

After:

Have made a start on the underbody itself. The rest of the framework hasn't really been touched yet (just a hose to get some crud off).

Lots of builtup grease/dirt has now been moved from the car to my skin

The protector bar in front of the diff has had a good scrub. I'm hoping the rest of the black stuff underneath will come up as good.

Still got a few more hours of lying underneath and scrubbing ahead of me.

I laughed when my housemate said "i honestly don't see the point." I think the point is Pride in ones vehicle :drive[1]:

Clay bar treatment on the weekend possibly....

If you want the black painted stuff underneath to come up looking nice and black, try Mothers Back to Black. I use it on my towbar to make it look nice and black :D

Heavy duty Lanolinon(machine wool grease). Dries tacky, sets like topcoat and sticks for ages, i've used it liberally for a while on just about everything metal including in the chassis rails and under the Paj and works wonders ;)
Get a hold of OZ Spray H/Duty in the spray bottle if you can, that can spray stuff is too thin.
