Washing reusable pads is straightforward: rinse in cold water after each use, then machine or hand wash with a standard detergent. The key to keeping them clean, absorbent, and long-lasting comes down to a few specific choices about water temperature, detergent type, and drying.
The Basic Washing Routine
Start by rinsing your used pad under cold running water until the water runs clear. This step removes most of the blood and discharge, so the actual wash doesn’t need to do much heavy lifting. Cold water is essential here. Warm or hot water will cook the protein in blood into the fabric, setting the stain permanently.
After rinsing, fold the pad and store it in a waterproof wet bag until wash day. Wet bags are small, zippered pouches lined with a waterproof layer that contains moisture and odor. They’re easy to toss in a bag for work or travel, and most are machine washable themselves. You don’t need to wash your pads after every single use. Rinsing and storing them in a wet bag for a few days before laundering is perfectly fine.
When you’re ready to wash, toss your pads in the machine on a regular cycle with your usual detergent. There’s no need for a special setting or a separate load, though many people prefer to wash them with towels or similar items. You can also hand wash them the same way you’d handle any delicate laundry item. Avoid scrubbing with stiff brushes, which can damage the waterproof backing or the absorbent layers inside.
Choosing the Right Detergent
The most important rule is to use an actual detergent, not soap. Soap is a milder cleaning agent that doesn’t have the power to clean through thick absorbent layers. Over time, soap residue builds up in the fibers, reduces absorbency, and causes lingering odor. This applies to bar soap, liquid castile soap, and homemade laundry mixtures, which are almost always soap-based.
Look for a detergent that contains enzymes, which break down proteins (like blood) and boost overall cleaning. Most mainstream detergents already include them. You might see “bio” or “plant-based enzymes” on the label. Concentrated detergents work fine as long as they meet the same criteria.
A few products to avoid entirely:
- Fabric softener. It coats fibers to make them feel softer, but that coating builds up and blocks absorbency over time.
- Dryer sheets. These contain fabric softener and cause the same buildup problem.
- Soap nuts. They release a natural surfactant when wet, but it’s essentially soap and lacks the cleaning power to reach deep into absorbent layers.
- Laundry strips. Convenient for travel, but generally not strong enough to thoroughly clean reusable pads.
Removing Stubborn Stains
Some staining is normal and doesn’t mean your pads aren’t clean. But if it bothers you, a few natural options work well as pre-treatments before your regular wash.
A cold water pre-soak is the simplest approach. Submerge the pad in a basin of cold water for 30 minutes to an hour before washing. For tougher stains, rub a small amount of lemon juice directly onto the stain and let it sit for a few minutes before washing. Baking soda also works: sprinkle it generously on the stained area, rub lightly, and let it sit before tossing the pad in the machine. White vinegar applied directly to stains before washing can handle more persistent discoloration.
All of these are gentle enough that they won’t break down the fabric or waterproof layers. Avoid bleach, which can degrade both the absorbent material and the waterproof backing.
Drying Your Pads Properly
How you dry your pads matters more than most people expect. Moisture left in the fabric creates conditions for bacteria and fungi to grow, so getting pads fully dry is a hygiene priority, not just a convenience issue.
Air drying is the gentlest option and what most manufacturers recommend. On a warm, breezy day outdoors, pads can dry in just a couple of hours. Sunlight has the added benefit of naturally lightening stains. Indoors or in humid conditions, expect drying to take significantly longer, sometimes up to 18 hours depending on the thickness of the pad. If you’re drying inside, choose a spot with good airflow. Hanging them near a fan or open window helps.
You can tumble dry on low heat if the manufacturer says it’s safe, but high heat can damage the waterproof layer over time. Whatever method you choose, make sure the pad is completely dry before storing it. If you fold a pad away while it’s still damp, you’re creating the exact warm, moist environment where mold thrives.
Storing Clean Pads
Once your pads are fully dry, store them in a clean, dry place. A drawer, basket, or fabric pouch all work. The only thing to avoid is sealing them in an airtight container while there’s any chance of residual moisture. Good ventilation prevents musty smells and keeps the fabric fresh between uses.
For carrying used pads when you’re out, a wet bag is the standard solution. Keep one in your purse or backpack. After changing your pad, fold it with the soiled side inward (most pads have snap closures that hold them in this folded position), tuck it into the wet bag, and rinse it when you get home. Used pads stored in a wet bag for a day are easy to rinse clean. Leaving them for multiple days without rinsing first can make stains harder to remove and allow odor to develop.
