Granite Landscaping rock cleaning?

[Kris Caswell]

Ran a search and couldn't find much on this subject. I had an inquiry about cleaning huge granite rocks on a regular basis. Client said that a lot of his rocks are delivered with these brownish discoloration on one side of the rocks. He'd like the rock cleaned up and looking uniformed if possible.

I did run a test today with 215 degree @3000psi and a green tip. We did have somewhat of a noticeable difference but not quite quite to the level I am pleased with.

Do you know what causes these stains?
Is there anything that can effectively clean these rocks up?

I remember the first time I was asked to clean rocks I could not believe my ears!! I was like "you want me to clean your rocks?"

Now I upsell home owners to spray down their rocks... And it works from time to time! haha

I have no clue how to help you out because we just spray rocks with water, maybe try F9 in a test spot? But I will say this:

ISN'T IT GREAT YOU ARE IN AN INDUSTRY THAT PAYS YOU TO SPRAY DOWN ROCKS?!?! HAHA

Ty lmao...

next they will be asking you to turn dirt into mud

Contact Craig. F9 comes to mind but not so sure that would be the ticket!

Green tip and hot water. I'm trying to see if there's something better we can offer.

Try One Restore real light spray and rinse off after a min dwell time, test it first on a spot. Let him know you are doing a test... One Restore works on everything...
