How do cleaning conditions affect dosing of detergents?

Amount of soil load, type of soils, cleaning process and water quality will all affect dosing. It is recommended to start at 1 oz./gallon of water. Dosing may need to be increased for heavy, dried-on, fatty / oily soils or when using tap water over 200 ppm hardness. Manual cleaning without the aid of impingement (spray pressure) may also require increased dosing.
