DOSAGE AND USE: A test before application is recommended, depending on the type of surface as well as the type and amount of dirt. Use in a bucket: 1-5% v/v (recommended 50 in 5 liters of water). Insoluble for very hard and dried dirt, apply on a wet surface, depending on the type of surface, rub and rinse with clean water. For sponge use, recommended dilution 1/100 with water in a small basin. For washing machine use, recommended dilution up to 50% with water. After washing the surface, rinse thoroughly and allow to dry. For areas with very hard water, it may be necessary to wipe the dry surface with a soft, lint-free cloth.
