Kirkland Signature Laundry Detergent Pacs

These pacs are specifically designed for high-efficiency (HE) washing machines. While they can technically dissolve in standard machines, they are formulated for the lower water levels and specific agitation cycles of HE units to ensure proper cleaning.

Yes. The formula uses specialized dirt-isolation technology that lifts stains and prevents them from re-depositing on your clothes, so you get a deep clean without the need for added dyes.

No, these pacs are engineered to dissolve fully in all water temperatures, including cold water. You can confidently use them for any wash cycle without worrying about residue left behind on your garments.

The formula is dye-free, which reduces the likelihood of irritation compared to detergents with heavy dyes. However, if you have severe chemical sensitivities, it is always a good idea to check the full ingredient list or test a small load first.

For most average-sized loads, one pac is sufficient. If you are washing an extra-large or heavily soiled load, you may want to use two pacs to ensure optimal cleaning power.
