Spotty vinyl siding after soft wash

Recommended Posts

Guys,

This vinyl siding that is about 20 years old was soft washed. After it was pretty much dry it looked very clean. However latter in the day the siding looked spotty / blotchy. It's faint but you can see it. We have not experienced this before. As you can see on my fingers it has a film of chalk. Does any one know to effectively clean this?

If it is a soap "alkaline" residue try some vinegar.  What was your solution ratio, how much detergent to SH and how many gallons of water?  From picture looks like I would spray some vinegar dwell a few minutes and rinse with water.

Did you use laundry detergent or soap?  I am using a product called Cling from Pressure Wash USA that works well with no residue but will be trying Slo Mo to compare it to.  It's expensive with shipping but works amazing.
