Learn the correct dosage and step-by-step process for using Signature Detergent Classic Gallon to get the best clean for your laundry.

Quick answer

Use 1 capful (about 1 ounce) of Signature Detergent Classic Gallon for a regular load, 2 capfuls for heavily soiled or larger loads. Always pour into the measuring cup or directly into the drum, not onto dry clothes.

Why dosage matters

Using too much detergent leaves residue on fabrics and can cause buildup in your machine. Too little leaves dirt and odors behind. The Signature Detergent Classic Gallon is concentrated, so a little goes a long way. The pump dispenser makes it easy to measure accurately.

Choosing the right amount

For a standard top- or front-load washer with a medium load, one full pump (about 1 ounce) is sufficient. For heavily soiled items like workout clothes or muddy jeans, use two pumps. For small or lightly soiled loads, a half pump works well. The gallon size gives you 126 washes at the standard dose, so you can adjust without worry.

Step-by-step guide

Check your load size and soil level: Sort laundry by color and fabric type. Estimate the load size (small, medium, large) and note how dirty the items are. This determines your dose. Common mistake: using the same amount for every load regardless of size or soil level.
Measure the detergent: Use the pump dispenser to fill the included measuring cup or a standard laundry cap. For a medium load, one full pump (1 oz). For large or heavily soiled loads, two pumps (2 oz). For small loads, a half pump (0.5 oz). Do not fill the cap to the brim—use the pump for consistent dosing.
Add detergent to the machine: Pour the measured detergent directly into the drum before adding clothes, or into the detergent dispenser drawer if your machine has one. Do not pour onto dry clothes as it may cause spotting. For front-loaders, always use the dispenser drawer to prevent oversudsing.
Start the wash cycle: Select the appropriate water temperature and cycle for your fabric. Signature Detergent works well in cold, warm, or hot water. For best results, use cold water for dark colors and warm or hot for whites and heavily soiled items. Hot water can set some stains—check care labels first.
Store the gallon properly: Keep the gallon in a cool, dry place away from direct sunlight and moisture. The pump dispenser helps keep the spout clean and prevents spills. Do not leave the pump on if storing on its side—it may leak.
