Laundry Booster & Household Cleaner

Improves Detergent Performance by 15%

Independent testing shows the washing soda boosts liquid detergent effectiveness by up to 15 percent on mustard and blood stains compared with leading value detergent alone. This measurable lift makes it the decisive spec for buyers who need stronger stain removal without switching detergents.
