So this is something that can't be done softwashing....?

ACid products are used to remove the concrete splatter. Gloves, Eyeglasses, steel brushes and lot's of labor. I did it a couple time many years ago. Decided I liked roof and house washing better. Typically when it's time for the Construction clean up the builder is out or low on money so theya re looking for cheap cheap cheap.  Just beware of this going in.

Be careful around the windows. If there is insulated glass, the acid could break down the seals and cause fogging over time. The acid will void the manufacturer's warranty on replacement glass.

 Using a pressure washer on these windows will also void the warranty and ruin the seal.

Doug,

 

      I have been told on more than one occasion from window installers that pressure washing an insulated window can ruin or "blow out" a seal if the cleaning contractor is not careful. This will in fact void the window manufacturers warranty.I have looked this info up, and attached two window manufacturers warranties.

See attached Limited warranties from Pella and Anderson windows.

Both Pella and Anderson include, the use of Brick wash or acids will in fact VOID their warranty.

Anderson states: exposure to conditions beyond published performance specifications.

I did not look up these specs, but pretty sure they are not rated for 1000+ psi. This can be a loop hole for the manufacturer to not warranty seal "Blow Out"

Anderson states: improper maintenance, such as use of brick wash, razor blades, sealants, sanding or improper washing.

Another Loophole for the manufacturer to not warranty a "Blown Out" seal As the manufacturer will make the final decision as to what went wrong, and why there was a failure.

So neither of these companies warranties specifically name "Pressure Washing"  as a reason to void their warranty, they do list "improper washing" which is open for interpretation.

We all know that a seal can and will blow out if care is not taken when  pressure washing. I have actually had customers tell me they have not had their homes washed because they were afraid of the window damage that a pressure washer could do. These were an EASY SELL for the proper Soft Washing service we offer

I do use this seal "blow out" information when talking with a customer about Soft Washing as opposed to Pressure washing.

I hope this helps.

We have used acid to clean multiple kinds of stains from block, concrete, and brick. You need to STAY AWAY from muriatic and hydrochloric acids. Contact Mike @ Eachochem he will help you find the product you need. They sell buffered acids that are easier to handle and we have had great results. He will probably recommend their NMD-80 which is designed for new brick construction washing and safe around windows as long as their not tinted on the outside, but anyway call MIke and he'll hook ya.

Also, pressure washing can blow out the perimeter waterproofing of the installation, creating a leaking situation. I ran into that occasionally in my former profession as an Andersen Window dealer.

Sorry, I will not be able to make it this week. My wife went back to college and I am in charge of the kids. Can't get away. Hope you video everything for me to purchase later.

 I got ya covered Mike!
