I just started a PW business and one of my first jobs has oilly residue on the walls. I used regular house cleaner with about 2500 PSI and it didnt do anything. How can i get this off without hurting the paint?
 
You have Lots of questions to answer first.
What kind of oil?
What kind of siding
is it painted
do you have hot water

do you have a picture of the house and oil stain?

You are using way to much psi for a new guy. 500-1000 psi should be more than enough for most house jobs.

Purchase professional chems and you will acheive the results you are looking for. A SH based cleaner should work for you.

What is your regular house cleaner anyway? How much dwell time are you using?

Be careful with the pressure or you may quickly enter the painting business. I use Sodium Hydroxide to break up grease and oil... If it a vinal surface it may be permanently stained.

SH is not a valid Chemical. If you are going to use shorthand use the real chemical name. You are looking for NaOH for Sodium Hydroxide. When you start doing abbreviations like this, the person you are talking to stands the risk of getting either the wrong chemical, or driving themselves nuts trying to find the chemical you are talking about.

Just my opinion.

Aplus... ME 0.2, I also read it as Sodium Hydroxide. I am pleased that B. Young offered a solution and advise rather than critisizing other peoples post's.

Scott,
Yes you are correct that SH is not listed that way in the periodic table. Neither is water(H2O) LOL!

My concern was that if I would have typed NaOH, raw unblended Sodium Hydroxide may have been purchased.

Now the user has a raw chemical with no ratio or blending instuctions as far as how to proceed.

We both know that could present deadly and devastating consequences.

By typing, use a SH based cleaner I thought I would be encouraging the purchase of an established commercial product.

This product would be required by law to have an MSDS(Material Safety Data Sheet) and would also list recommended useage guidlines on the product.

I am glad you all feel that way,a nd that you all understood. My concern is that some idiot would have taken it as gospel and gone looking for a mythical chemical. For me it is easier to make it so it cannot possibly be misunderstood, especially when it comes to chemicals. BEyoung, since you put it as SH based chemicals in your original post, it would not hav been too far a stretch to write NaOH based chemicals in the post.
Water is not a base element. When you start using letters, many people will assume you are talking base elements. [hand] I am sorry if anyone thought I was being critical. I was trying to make it clearer and more useful.
