Stains

How Are Stains Treated?

1. TANNIN: Organic matter in the well water - decomposed plant material, etc. - leaves this stain.
   • These stains are best removed by household bleach - diluted. If bleach does not remove the stain, the stain may be caused by iron oxide - rust!
2. IRON: Ferrous iron in the well water combines with oxygen to form ferric (iron) oxide. This is the rust stain seen on surfaces hit by the spray.
   • As an inorganic stain, iron oxide is best removed with acid.
   • American Hydro makes an excellent biodegradable, grass and plant friendly, rust stain remover - Rid O'Rust Stain Remover.
   • Rust stains are best PREVENTED with Rid O'Rust Formula products.
3. HARD WATER: Crystals of calcium carbonate deposited by the well water leave a white scale on leaves and other surfaces.
   • They can be wiped off leaves with a mild detergent and water solution.
   • To PREVENT hard water residue, use Rid O'Rust Formula products.
