If you did one and it left marks you are #1 to close and #2 too much pressure
at what psi are you washing with?
at what psi are you washing with?
Seeing your such a pro, what do you use for psi ? I also have a 3300 psi 7.0 hp with a cat pump is that more to your liking and whats the difference if the house is not dirty and only has chalk on it.By the way thanks for your help with my self esteem. Big Guy ! i I just started washing and i was looking for some answers. You might want to check into some classes on "How to be a motivational speaker" . Thank God for great people like you !!!

Hey I don't think he was being a smart a$$
he was telling you that the chalk was oxidation and you need a cleaner that will clean it up
and far as the 2600 psi that is too much psi on the home .Slow it down know one is here is busting your chops this bbs is here to help..
The key to washing is let the chem do the work for you all you have to do is rinse with low psi
if you need more help feel free to email me
mark.cauldwell@yahoo.com
PS some will sue for nothing..keep that in mind
we all started out slow and grew from there

Not trying to being an ass but you really should learn the proper way to clean before you damage someone's property. Research the proper chemicals to clean (there are several that will remove oxidation easily) as well as the proper PSI to clean vinyl. Under 300 PSI is ideal. With 2600 PSI, you are using too much pressure which can lead to gouging the vinyl, chipping paint, blowing out chaulking, and forcing water behind the vinyl siding - all of which isn't good. Do you let a mechanic that has no experience or knowledge work on your car? Why should someone hire you when you refer to the oxidation on their house as chalk?
BTW - your previous customer was happy with streaks all over his vinyl siding?

Easy now
Hi Jav,
Try not to take things so personally. These guys here have TONS of experience that everyone can benefit from. The problem with things like forums, emails, IM chats, ect. is you're not talking face to face with that person so you're not hearing their tone of voice, seeing the body language and expressions on their faces. So it's very easy to take something that was typed wrong or personally. Been there, done that myself, as I'm sure many have.
I'm sure if it were possible to get yourself and these "repliers" in a room personally and ask your questions, you'd get pretty much the same responses, only you'd be able to see and hear the tone of voice and facial expressions and I don't think you'd feel the way you do or take it the way you did. Of course, there'll always be the self proclaimed expert on everything smartass types where ever you go. But I don't think there are very many like that here on this board. A reply might appear that way to you, especially when you're starting out, inexperienced and probably feeling a tad insecure, especially with the outcome of the first place you mentioned. So relax and ask your questions. The replies so far are giving you information that is very valuable.
In my opinion, the only stupid questions are the ones that don't get asked. And that can get you into trouble in more ways than one. Plus, you want to do a good job and the more informed you are, the better the final outcome.
Now, for my 2 cents worth. The lines and uneven marks that you mentioned can also be caused by improper technique with your gun. Don't get in a hurry, be sure your strokes are laied on at a steady speed, straight as possible and be sure to overlap your strokes by about half. In my neck of the woods what happened to you we call "tiger striping". Oh, and your nozzle selection plays a big part in this.
Don't use your 0 or 15 degree nozzles.
I do have a question for you through. Was that first place really vinyl siding or was it aluminum? The reason I ask is the color of vinyl siding is mixed/moulded right into the vinyl when it's manufactured. (Unless the homeowner painted it a different color in the past) Whereas alunimum siding does have actual coats of paint on them, which does oxidize when exposed to the elements. I personally have never seen oxidation on vinyl (unless painted). Painted surfaces...oh yeah, big time. I just finished a house/garage/concrete job. (all vinyl siding) The place was located right under the air traffic patterns of Detroit Metro Airport. Took me a couple seconds to realize that much of the grime was from jet exhaust. Tell ya what, that is the best looking house on the street now and had neighbors swarming me for business. It was a total transformation, just beautiful.
Lest ye think I am one of the big dogs here, please refer to the Equipment Help section, the thread titled "Opinions before I buy" and you'll learn a little about me. I'm small potatoes compared to most all these guys. You'll see how I could have taken some of the responses out of context. I value their input and at the end, I had to clarify a few things.

I don't know why, but blue or blue/grey older vinly is the only vinyl I have seen with oxidation. I usually educate the customer about the problem and inform them that I will not "pressure wash" so as not to cause all thsoe lines and marks you are referring too. Sometimes it will also leave a splotchy appearance.
I recently did one using a percarbonate based cleaner which is much safer and eco friendly compared to bleach. I did it with very low pressure, less than 200 psi. It did not leave marks, but it did partially remove some, but not all of the oxidation leaving the "splotchy" appearence.
If the siding is dirty or mildewed, all that is needed is your normal house wash mix of bleach and an all puporst cleaner. Spray and rinse is all you will need. Don't even try to remove the oxidation.
I see that some guys say butyl will remove it. I don't know because I haven't tried, but it is possible. But I would think you would need a little more pressure, over 200 psi, and very good lance technique to remove the oxidation evenly.

We used to run a a mobile wash business before entering in to equipment sales & service, we washed thousands of mobile homes / manufactured homes , we usually ran two or three man crews depending on the workload.
One guy soaping using a mild alkaline soap, another guy or two brushing the siding, on badly oxidized areas we would pre-spray a higher concentration of the same product.
We removed most oxidation although we did advise customers with badly oxidized siding that we may not be able to remove all oxidation / chalk. [whatup]
