Irrigation rust

Need some help with this one. Used F9 Groundskeeper 1:10 mix, White Ox, and EBC. All 20 min dwell times with rinsing in between.


do you know if the concrete had been sealed?

You need F9 BARC and follow the steps in the F9 cookbook.

Where are the after pics from a section where you’ve cleaned it? Those are pre-clean pics.

These pictures are after cleaning.

How did you clean it and with what psi? Not a single surface cleaner stripe anywhere or blade of grass disturbed along the sides. No one is that good. Plus it’s still dirty. Of course sometimes OX will give you that splotchy look. Did you try some SH on it. Don’t even see much irrigation stains. You have any pics of what it looked like after it dried?

This is a returning customer. I cleaned the whole driveway back in September, following your guidance from the videos you’ve done. Mentioned it to them about the stains then and they just reached out the beginning of the week to get the stains removed. I’ll have to stop by and get some pictures of it dry.

Whew, thought we were all going to have to come take lessons from you. Did you use any SH on it? And why the 2 degreasers and what did you use the Ox for?
