Need y'alls expertise and recommendations on how best to clean this slate paver patio. It's mostly foot traffic grime but outer edges gets some golf cart tire marks too. The slate is set in concrete so no grout issues. Also- what is a fair price per sq ft to do this? Thanks gang!
Steve, this looks like a job for Terra Wash. 50/50 in a pump up sprayer and a medium bristle brush. Since you're dealing with mostly grease and grime, I don't see the need for bleach/Green Wash solution.
Hey Bob, I've heard you and others talk about using a medium bristle brush for different applications. Can you or someone else post a link or a picture of what you mean by 'medium' bristle? Thanks!
Steve, I agree with Bob. Terra Wash is great on tire marks and that kind of non organic soiling. Depending on how heavy the staining and how porous the surface you will need to scrub for a bit, but with slate pavers I would guess it wouldn't be that tough to get the surface looking nice again.
Thanks guys for the suggestions. Project grew once I got there : ) . I convinced them to add about 8000 sq ft of stamped concrete driveways and walkways to the slate pavers clean, plus an additional 2500 sq ft of terracotta stamped concrete at an outdoor patio/cafe. Job total now approx 12,000 sq ft.
I did a small sample test of Terra Wash 50/50 and then even straight Terra Wash right next to an area done 3 months ago by a surface cleaner. Looks like the surface cleaner wins hands down on this one. Dirt is mostly rubber tire marks from golf carts. No oil or grease. The outdoor patio/cafe has kitchen grease tracked by servers to customers (pic 2)
Question for you pros- Do you think hot water with surface cleaner is the way to go? or will cold water do it? Appreciate the help!
Hope you don't mind me posting this here Steve. Thought it better to put in one thread than make another. I have a slate driveway and wall to clean as well, similar to yours.
They're covered in white stains, I'm thinking calcium or efflorescence? Looking for advice on making it look like new again.
See pictures.

Remember everyone with regards to contaminants like oil, grease and tire rubber, "If you free it, you own it". Please complete a Site Disbursement / Recovery Plan for the cleaning so you can show the local authorities how you are keeping the waste stream onsite or collecting through extraction. Then call the local water district to find out if you can soil percolate onsite, or drain to sanitary sewer or if you need to take the waste stream with you. Then make sure you charge appropriately.
FYI- the price they offered me while 40% less than I quoted, was still 10% higher than their other bids. Lots to learn.........but felt good knowing I out sold several long established companies and we have been officially open for about 60 days : ).
