How to Use
Read and follow garment care label instructions, then sort laundry. Always test on an inside seam for colorfastness before washing. Measure powder with the provided measuring scoop — fill to line 1 for medium loads, line 2 for large loads. Add detergent to the drum of the washing machine, then add clothes. For stain pre-treating, make a paste with powder and water, apply directly to the stain, wait 5 minutes, then wash as usual. For surface cleaning, dissolve in warm water and apply to the surface with a cloth or sponge. Keep out of reach of children. Eyes: Rinse well with water for 15 minutes. Call Poison Control 1-800-774-2678 or a doctor immediately if swallowed.

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 $0.24 per load, it is one of the most cost-effective laundry detergents available, significantly lower than premium liquid detergent or pac formats.
