I have a project this week cleaning a concrete pool deck that has fertilizer stains. Customer fertilized his lawn last week and the overspread got on on his pool deck. Planning to use F9 but I'm wondering whether to PW first , as the F9 instructions say, or rinse with garden hose and then broom surface as it shows in the F9 YouTube video. Any thoughts?

F9 should work. It is the only thing I have seen take magnesium stains off of concrete. You generally get two pellet stains, one from iron and the other from magnesium. Magnesium is the toughest to get out.

The last one I did had no effect on the stain followings craig's advice. I would do a test spot before going any further with the process and yes you will to power wash first.

Clean first....it doesn't take long and better to be safe than sorry.

Pressure wash first, app,y straight F9, let dwell, pressure wash again. Repeat as needed. It depends how deep the stains are. We did a patio last year that took four applications...charge accordingly.

Thanks to all who responded. I also exchanged a cew emails with Craig Harrison at F9 who outlined for me the same priocess that Doug Rucker listed in his post. He also referred me to the YouTube video on removing battery acid stains on a concrete driveway. Using a PW first to open up the pores of the concrete is key to having the F9 product work correctly.
We are currently waiting out the weather today and tomorrow. When we complete the job, I will put up another post with the results.

If you forget step one your quality of work can be open for debate. Pictures have saved my behind a few times.
Interested in before and after picks, and to hear about your out come. I haven't tried f9 yet... have some but haven't used it.

The Restoration Soft Wash Team went to work on this badly stained pool deck Following the steps that Doug Rucker outlined in his post. It took a few more applications of F9 Barc but the customer was pleased with the results.

Awesome results Doug! Nice work.
A small tip - I noticed that the grass is lightly browned a little on the edges. This happened to me a couple times, especially when doing the several applications that fertilizer stains require. We now take the cardboard sheets from the F9 boxes, and hold them as barriers while spraying along the grass edges. Now we never have any dead grass along the edges.

Thanks again to all who commented. Actually, the yellow grass along the edges was like that when we got there (see the "Before" photo). But thanks for the tip Brandon.

Has anybody tried out this tool versus the cardboard option? https://www.youtube.com/watch?v=SUv_L48LZbg, (also http://surfaceedger.com/Blank.html) called the "Surface Edger" It's $99 or $170 depending on which model you buy (with/without the wand). It looks like it works well, at least on straight line edges. Not sure how well it would work on curved surfaces like around this pool though. The outside (left turn) edges would probably work, but the other turns would probably put the nozzle directly into the dirt, at least partially.
