Hi Guys,

What temp is need to emulsify oils, I've read somewhere that 150-220 F. is good but my experienced friend is telling me I need 300. I may be picking up a karcher hds 501 that puts out 180 f. max on avg. I deal with a lot of lubricants from cars like rust proofing, engine grime etc. from engine bays of cars.

what I surmise from what I hear in the field..

the more temp you can throw at oily residues, the more completely you can vaporize them.

180 degr.F .. is never really fast enough to be competitive, without "abusing chemicals".

200 - 230 degr.F is "shear-effect" .. grease melts away, and pressure shears it fast !

.. throw 230 with 4000psi through a surface cleaner.. for Rockin' WorkSpeed.

260 to 275 is "vaporizing" .. oily residue vaporizes right out of the surface,

.. and you're still at "saturated steam", so the water is still delivered with velocity and impact.

.. and you should see what happens to gum at 1000 to 1500psi !

300 - 325degrF. vaporizes deeply from porous surfaces, and requires minimal soap,

but .. hose-safety limits pressure to below 500psi.

..Do NOT compromise safety.
 
Thank you for your help Jerry, I'd love to use 4000 psi but >2000 psi will not work for my application. My friend's shop is equipped with a large Landa unit that does 300 f but below 500 psi as you've specified. He showed me how fast rust proofing and oils come off with it. I'd love to get something like that but I need something I can be mobile with.

What are you actually trying to clean?
 
I think he said "I deal with a lot of lubricants from cars like rust proofing, engine grime etc. from engine bays of cars." so im guessing maybe repair shops or parts on cars with grease build up that needs to be cleaned before work can be done.. just a wild guess though until he clears it up. That little temp guide you wrote is pretty dang cool!!! Thank you! My Alkota 216ax4 1600psi 190deg does the job for my kitchen duties.. although im sure I could def. use something hotter and higher psi. We shall see....
 
portable sytems are available (less than 500 lbs) which can do 4@4000, and completely flow-pressure-temp adjustable to 300 degrees.
 
For a great job that is competitively fast, a good degreaser and hot water is always great.

I have never had good results with just hot water or a steam machine without degreasers or other chemicals on heavy equipment that was going to be serviced or painted, the mechanics or painters are very picky about this stuff.

Give it a try and see how you like it, no matter what anyone says, it is you doing the job, making the money so it has to work for you, be efficient but mostly, it has to do a good job that you are putting your name onto.

Something to remember is that you might have decals, paint, hoses, wires, etc.... that you have to think about that might be there also and you really don't need 300 degrees to clean engine bays or heavy equipment. I have never heard of anyone out there that does this type of cleaning that says that they use water that hot for cleaning. There is no need for water that hot in probably 95% to about 99% of most cleaning jobs that you are degreasing engine bays, heavy equipment, vehicles, etc.....

There is a lot of mis-information out there and misconstrued information out there, look into the type of cleaning you are going to do and always consider the sources of your information to be sure they are apples to apples and not apples to morons.

At the Las Vegas event years ago, we used a machine that was making over 300 degrees hot water and guys were trying it out to remove gum. We were told that over 250 degrees the gum would "vaporize" and we would be amazed. That was very funny! hahahahaha many guys got to try to remove gum at the Vegas DMV and suddenly realized that hard, old, baked into the concrete gum is harder to clean than fresh gum or gum that is just months old.

When Tony Shelton started up his Landa hot water pressure washer, the gum came off at about the same speed as the machine that made water over 300 degrees, I tried both, Nigel tried, Tony tried, Chris Shelton tried and other people tried as well and there is even a youtube video of this happening, I might be able to find it and post a link later on but my point is this, you don't need super hot water to do degreasing when you use some good degreasers.


Good luck.
 
Apologies for the late reply but I detail cars, I hate using solvents to clean gunk out of engine so I rely on steam or hot water pressure washers. ^Also the above statement is right, rust proofing that has been on the car for 8+ years is way harder to clean than cars with 2+ years of rust proofing on them, no matter what machine you're running. Anyways I think I want to go ahead with the Karcher.
