Unhappy Any advice on cleaning chalking paint?

Hi all, thanks for reading.

This week I received a call from another local painting contractor that was wanting some help on washing a house for him. He attempted to clean it but was not able to get it very clean. He has been painting for 20 years and had not run into a scenario like this.
The paint is Chalking badly. The house was painted in 1992 with a high end Benjamin Moore paint that was the latest greatest thing... I believe it is the self cleaning paint that I have heard about. Now this paint I believe is supposed to slowly chalk over time and the rain and wind is supposed to help clean it off.
(correct me if i am wrong)
The problem with this house is that it was right on a major buss route that had and still has a lot of traffic that drives by and is right under some older and some newer buildings. The oils, exhaust, dirt, all seems to be holding on to the "chalk."
When we went to clean it the oils and chalking wouldn't budge without a strong cleaner, aggressive brushing, and 175 deg water.
This is a very laborious process.
I am hoping that someone might be able to recommend a product or system that would help get this house clean without scrubbing every square inch.
BTW it is a very large 3600 sq ft home built in 1910.

Any help and/or advice would be greatly appreciated.

Thanks, is offline

Paint chalk is a powdery substance that commonly forms on painted exterior surfaces exposed to frequent sunlight or dry weather. The powdery chalk is paint pigment residue escaping from underneath the weathered coating. Excessive chalking causes the color of a paint finish to fade and chalk exposed to rain may also leave noticeable streak marks on the surface. Cleaning chalking paint is an essential step for a successful exterior repainting project. Painting directly over chalk prevents proper paint adhesion leading to paint failure and additional chalking.

Thanks for the reply Justin, I understand that it needs to be cleaned well, I am looking for a solution to clean it that wouldn't involve a heavy scrubbing. Maybe some chemical to use.

I would mix up a strong TSP solution mixed with bleach and
apply with a dedicated chem pump. Then i would have 2 or 3
Guys hitting every inch with the pressure washers.

TSP is the tool for this job imo.
good luck

You all have provided great solution over here about cleaning chalking paint. I also like to suggest something over here on the same topic. When are going to choose a paint for your house, then you should keep in thoughts what type of home it is, and how you want individuals to experience when they are in that place?

Hey there,
It seems like a major problem and as you told that you used lot of water and some agent to clean it but it still remain then I think you must go for some strong chemicals and it is totally foolish thing if you are thinking that it will clean automatically and I think there is also another solution for this that you can paint that wall again with different color. My be it will helpful for you.

Thanks for the replies.

I must say the the heavy TSP, Bleach, and some other degreasers in the solution, With a high volume ~180 deg water, did ok with the cleaning. After that in certain areas it did need to be wiped with a terry towel and it seemed to come off easy.

The solution we used was strong enough that the rinse water stripped the paint off the deck really easy.

Again Thanks for the suggestions.
