How are stains removed and/or prevented?
1. Tannin:
Organic matter in the well water such as decomposed plant material, etc., causes this stain. We find that stains can appear with tannin in excess of 3 ppm.
These stains are best removed by diluted household bleach.If bleach does not remove the stain, the stain may be caused by iron oxide, or rust!
2. Iron:
Ferrous iron in the well water combines with oxygen at the sprinkler head to form iron oxide
(rust).
This is the rust stain seen on surfaces hit by the sprinkler water.As an inorganic stain, iron oxide is best removed by our Rust Stain Removers.
Our rust stain removers are an excellent – biodegradable, grass-and plant-friendly rust stain remover.
Rust stains are best prevented with American Hydro Systems Formula products.
3. Calcium (Hard Water):
Crystals of calcium carbonate deposited by the well water leave a white scale on leaves and other surfaces.
To prevent hard water residue, use Calcium Cracker. Hard water residue can be cleaned off most surfaces
with Rusty.
