    Cleaning Pre-cast...Issues

    Doing some testing prior to submitting proposal. Large Building with pre-cast facade

    Test #1: D/S standard mix (3 gallons SH + 2 gallons water) 20 minute dwell with low pressure rinse= Looks better but far from clean
    Test #2 Dedicated pump with 50/50 mix, 20 minute dwell with high pressure rinse= looks better but not 100%

    Open to options and advice

    Many Thanks

    Got it done! Used a mix of 9 percent sulfuric acid. Short dwell and cleaned with high heat.
    Just posted for future search inquires.
