How to Use
As a laundry booster, dissolve ¼ cup in water along with your regular detergent before adding clothes; for HE washers, dissolve it in water first rather than adding powder directly to the dispenser. For carpets or upholstery, blot excess liquid, apply the dissolved solution, let it stand 5 to 30 minutes, then rinse thoroughly with clean water. Always dissolve fully in the warmest water available, and keep the box out of reach of children.

Frequently Asked Questions
What surfaces and fabrics can I use Kirkland Signature OXI Powder on?
It's designed to work as a laundry booster with your regular detergent, and on its own for carpets, upholstery, pet stains, red wine and coffee stains, patio furniture, and grout. Because it's chlorine-free, it's suited to colors and delicate fabrics that can't tolerate chlorine bleach. Spot test on an inconspicuous area first for fabrics you're unsure about.
How do I dose Kirkland Signature OXI Powder for a laundry load?
For top-load washers, add ¼ cup to water along with your regular detergent before adding laundry, using more for heavily soiled loads. For front-load or HE washers, dissolve ¼ cup in water first, then pour it into the drum before adding clothes, rather than putting undissolved powder into the dispenser.
Is Kirkland Signature OXI Powder safe to store and use around the house?
Always dissolve it fully in warm water before use and don't store a mixed solution in a sealed container, since the oxygen reaction can build pressure. Keep the box out of reach of children and pets. If it contacts eyes, rinse immediately with water, and seek medical attention right away if it's swallowed.
How many loads does one box of Kirkland Signature OXI Powder cover, and where is it made?
One 176 oz (11 lb) box is rated for about 328 wash loads when used as a laundry booster according to the usage instructions on the label. It's made in the USA and distributed by Costco Wholesale Corporation, and Real Prime Deals ships this bulk box fast from our New Jersey warehouse.
