so i'm happy with my surface cleaner running on my hot water unit. i know some of you guys xjet straight 12.5% on driveways afterwards as a brightener, but what's the easiest way to use oxalic or citric acid. I saw someone on an earlier post say they pump spray?! Yikes. A whole driveway pumpsprayed! Not for me. I mean goodness, why not pre-mix and use a pump to apply or something. I need to know a good ratio for oxalic acid to either pre-mix and use my pump with, or to xjet. if you've got a better brightening method i'm all ears. thanks.
