    Anyone know of a good product for getting iron stains (rust) off of sidewalks? Every once in a while one of my crews accidentally stains someone's driveway. Pressure washing definitely doesn't work. We've been using a chemical they sell at the local turf store called "Miracle Rust Away" and it works pretty good but it isn't 100%. Just wondering if anyone knew of something better.

    But be very careful with it.......It will not only kill any grass or plants it touches, but will get you and your guys too!! Follow all the instructions on the MSDS to the T!

    Where would I find this nasty stuff?
     
  4. Try a local swimming pool place or store. They carry it
    as a ph adjuster for pool water.

    Cheaper way to go and works for me.

    Take a can of Coke, pour directly on stain, a little at a time. let set about 30 minutes, pressure wash off.

    Amazing what this stuff coke will do.
    Just my .02 cents.

    Good Luck.

    Go to your local hardware store and purchase a bottle of Calcium, Lime & Rust Remover. They are about $4/qt. and $12/gal. The stuff works well and is great for soap scum & rust stains around your shower, tub, toilets and sinks too. It is found in the area of the store with the Drain Cleaners.

    Mark

    Coke does some amazing things... I wonder what it is doing to my stomach!!!

    The CLR is good on rust stains on Stucco Walls, Vinyl Fencing ....try it first ..but on cement drive ways & retaining walls you may try

    ..liquid pool chlorine ... 1/4 chlorine 3/4 water with a few drops of detergent (to foam an let you see the work area) Spray the mixture on one area at a time and allow to soak for a few minutes ....using a strong hose to rinse the area thoroughly ...the chlorine removes mould and pollution stains very quickly but must be hosed off before it dries ....if you have some precious or sensitive plants then I suggest you cover them with a plastic sheet before you start or give them a good rinsing with the hose after you rinse the wall ....

    But if all else fails ....the MURATIC ACID will DO THE JOB ....but be real CAREFUL with this stuff .....no exposed skin ....eye & mouth protection ...

    Go to the Dollar General Store (if you have them there) and pick-up THE WORKS tub & shower cleaner.It's got phosphoric acid in it and it works great.
