Kirkland Signature Ultra Shine Dishwasher Detergent

Kirkland Signature is the private-label brand of Costco Wholesale Corporation. Launched in 1995, the brand was created to provide high-quality alternatives to national name brands at a lower price point. The Ultra Shine dishwasher detergent specifically competes with major household brands by offering professional-grade cleaning performance.

While Costco manufactures many of its Kirkland Signature products through partnerships with third-party manufacturers, this specific cleaning line is primarily produced in the United States to serve the North American market. However, because Kirkland Signature is a global brand sold in Costco warehouses worldwide, regional manufacturing partners are often utilized to optimize logistics.

Costco Wholesale Corporation remains the ultimate owner and distributor of the brand. Headquartered in Issaquah, Washington, Costco is one of the world's largest retailers, consistently maintaining strict quality control over its Kirkland Signature line to ensure brand loyalty among its membership base.
