    Default Pressure Washing Concrete

    I have a lot of concrete I need to clean and maintain. What works best? Those brooms, straight or rotating? Or just use the gun?

    I have the rotating kind that works as good as I could ask for.

    Guns seem to always leave streaks for me.

    I have had success mixing bleach 50/50 in pump sprayer and then using the gun. Seemed like streaking was minimal.

    Use the gun with the nozzle that allows you to effectively clean the most area at a time (without having to make multiple passes). And GPM is almost as important as PSI.

    You can rent the attachment to wash concrete, works well.

    I would rather buy it and have it at the disposal of my sons whenever I deem it necessary.

    I've used one of these and it works very well.

    Go with the rotating surface washer and make sure your pressure washer meets the minum requirements of the surface cleaner or you'll be working twice as hard.

    GPM is more important than HP- we pressure wash docks all the time and either use a flat surface rotating cleaner or a turbo nozzle( rotating spray tip) depending on the condition of the wood and if we are also pressure washing the handrail.
