A heavy-duty chlorinated dish machine compound, buffered to control water hardness from 0-35 grains hardness. Ultra eliminates scale in the wash tank, is buffered against the etching of glassware and effectively prevents hard water build-up on dishes and glassware in extremely hard water areas. Ultra will extend the life of dish machine tanks and will absorb up to 20% to 25% more soils than the majority of dish compounds. Consequently, it offers extended mileage which reduces the cost factor by up to 15%.
