Learn exactly how much Soak Laundry Care to use for hand washing bras and panties. Get the right delicate detergent dosage for a no-rinse lingerie wash.

Quick answer

For hand washing bras and panties, use 1 teaspoon (5 ml) of Soak Laundry Care per 1 gallon (3.8 L) of cool water. That small amount is enough because the formula is concentrated and rinse-free. If you are washing only one or two items, you can use 1/2 teaspoon in a small bowl of water. Always check the bottle for the most accurate guidance.

Why the right dose matters more for lingerie

Delicate fabrics like lace, mesh, and microfiber hold onto detergent residue. Too much soap leaves a stiff, itchy film that can irritate skin and dull colors. Too little soap won't lift body oils and deodorant buildup, so bras lose their fresh feel. Because Soak Laundry Care is no-rinse, the dose you measure is the dose that stays in the fabric. That makes precision more important than with a regular wash cycle.

How to measure without a detergent cap

Soak Laundry Care comes in a bottle without a measuring cap. Use a kitchen measuring spoon: 1 teaspoon for a standard sink or basin. For a single bra, 1/2 teaspoon in a small bowl is plenty. If you prefer pumps, one pump usually equals about 1 teaspoon, but check your bottle's pump style. When in doubt, start with less—you can always add a drop more if the water feels too slick.

Adjusting the dose for water hardness and load size

Hard water minerals can make detergent less effective, so you may need an extra 1/4 teaspoon per gallon if your water is very hard. Soft water needs less—stick to 3/4 teaspoon per gallon. For a large load of 6 to 8 bras and panties, use 1.5 teaspoons per gallon. Never double the dose just because the load looks big; extra soap won't rinse away and will leave residue.

Step-by-step: How to wash lingerie with Soak Laundry Care

Fill a basin with cool water: Use 1 gallon (3.8 L) of cool or lukewarm water. Hot water can damage elastic and set stains. Checkpoint: Water should be comfortable to touch, not hot.
Measure 1 teaspoon of Soak Laundry Care: Pour 1 teaspoon (5 ml) into the water. For a single item, use 1/2 teaspoon in a small bowl. Common mistake: Pouring detergent directly onto fabric. Always dilute it in water first.
Submerge and gently squeeze: Place bras and panties in the water. Gently squeeze the suds through the fabric for 2–3 minutes. Do not rub or wring. Checkpoint: Water should feel slightly slippery, not thick with bubbles.
Let soak for up to 15 minutes: For everyday freshness, 5 minutes is enough. For heavier soil, soak up to 15 minutes. Do not leave overnight. Common mistake: Soaking too long can weaken fibers and cause odors.
Remove and gently press out water: Lift items from the basin. Press between a clean towel to absorb excess water. Do not rinse—Soak is no-rinse. Checkpoint: No soapy feeling should remain on your hands after pressing.
Lay flat to dry: Reshape cups and lay bras flat on a towel. Hang panties by the waistband. Avoid direct sunlight and heat. Next step: Store only when completely dry to prevent mildew.
