Frequently Asked Questions
- Can Kirkland Signature Powder be used as a stain pre-treater?
- Yes. Kirkland Signature Laundry Detergent Multipurpose Powder is specifically designed for use as a stain pre-treater. Make a paste by mixing the powder with a small amount of water, apply directly to the stain, allow to sit for 5 minutes, then wash as usual. The OXI Technology in the formula is particularly effective on protein-based stains (blood, grass, food) and oxidizable stains (wine, coffee, tea).
- Is Kirkland Signature Powder safe for HE machines?
- Yes. Kirkland Signature Laundry Detergent Multipurpose Powder is compatible with both standard and High Efficiency (HE) washing machines. For HE machines, use the line 1 measurement (medium loads) to prevent excess suds. The formula is designed to rinse cleanly from HE machines without leaving residue.
- How does the 200-load count compare to other detergents?
- The 200-load count is based on medium loads using the scoop filled to line 1. For large loads (scoop filled to line 2), the box provides approximately 100 loads. At $47.99 for 200 loads, the cost per load is just $0.24 — making it one of the most cost-effective laundry detergents available, significantly lower than Tide PODS ($0.38-0.49/load) or Tide liquid ($0.31/load).
