Technical Notes


  • A powerful acid that can be used to treat oxide stains such as rust or aluminium stains however it requires careful handling.


  • Removing iron stains in laundry (For fixing not prevention, correcting iron stains - Use oxybleach for prevent. If alot of iron staining increase oxy bleach).Used as pre soak 1:10 solution (note: Constant use will deposit minerals in machine when reasts with hard water).
  • Remove rust stains from concrete etc
    Method One
    1. Wet area to be cleaned ( a very small amount of dish detergent may help , but not essential)
    2. With care spinkle a small amount of the oxalic acid crystals on the staining and work in with a broom or deckscrub.  Hard scrubbing should not be necessary.
    3. Leave wet for 15- 20 minutes and re- broom.
    4. Hose away after another ten minutes (times are not critical and are suggestions only)
    5. Repeat if necessary
    6. Using lighter applications and repeating – is preferable to using a larger amount of chemical and trying to do the job all at once.
    Method Two
    1. Make a 10% solution and use as above
  • Treating water bores high in iron
  • Controlling veroamite in bee hives.
    We have bee Keepers using this for controlling veroamite in hives . Our grade is suitable (note the 0.001 on the heavy metals is basically saying that these are below the normal detection limits , and not meaning that there is that much in there)
