We have strict standards before considering a product greywater safe.
All of our products have negligible phosphates, use biodegradable surfactants and nearly all, except our Earth Choice & Earth Choice Dishwashing Powder contain low enough sodium levels, making them grey water safe. These products also do not contain any ingredients that are toxic to plants.
Our Dishwashing Tablets & Powder have a moderately high level salts, which with the lower level of water used in dishwashers and food residue make it unsuitable for grey water. Kitchen waste water is often classified as “black water” due to the food residue and is therefore not suitable for use as Grey Water.
Please use our dish tablets and dish powders in standard sewer or septic system where the water will be treated and disposed of properly.
