Yes period underwear is convenient, eco-friendly, and a lifesaver during that time of the month but to keep them in tip-top shape, proper care is essential. This article is your go-to guide on how to wash period underwear effectively. Let’s dive in!

Background on Period Underwear

If you are new here let’s give you some background on how period underwear works. Period underwear, also known as period panties, are specially designed undergarments that provide extra protection during menstruation. They’re made with multiple layers of fabric to absorb menstrual flow, preventing leaks and keeping you comfortable.

Using period underwear is a game-changer. They reduce the need for disposable menstrual products, saving you money and helping the environment. Plus, they’re super comfortable and can be worn alone or as backup protection.

Pre-Wash Preparation

First things first, handle your used period underwear with care. Rinse them in cold water as soon as you can. This helps to remove most of the blood and prevent stains from setting in.

It’s also a good idea to wash your period underwear separately from your regular laundry. This prevents any potential cross-contamination and ensures your period panties get the special care they need.

Washing Methods

Hand Washing

Hand washing is the gentlest method for cleaning period underwear. 

Step-by-Step Guide:

  1. Rinse the underwear in cold water to remove excess blood.
  2. Fill a basin with cold water and add a mild detergent.
  3. Soak the underwear for about 30 minutes.
  4. Gently rub the fabric together to loosen any remaining blood.
  5. Rinse thoroughly with cold water until the detergent is gone.
  6. Squeeze out excess water without wringing.

Machine Washing

If hand washing isn’t your thing, you can machine wash your period underwear. All Ruby Love products are designed to be machine-washed and dried. Machine wash cold with like colors. Tumble dry on low heat. Do not use fabric softener.

Step-by-Step Guide:

  1. Rinse the underwear in cold water first.
  2. Place them in a mesh laundry bag.
  3. Use a gentle cycle with cold water and a mild detergent.
  4. Avoid using fabric softeners or bleach.

Choosing the Right Detergent

Detergent Types to Avoid

Stay away from harsh detergents, bleach, and fabric softeners. These can damage the absorbent layers and reduce the effectiveness of your period underwear. Think of brands like Woolite or your favorite non-toxic laundry detergent. 

Opt for mild, unscented detergents that are free of dyes and harsh chemicals. Eco-friendly detergents are a great choice as they’re gentle on both your underwear and the environment.

Drying Period Underwear

Air Drying vs. Machine Drying

Air drying is the best method for drying period underwear. It preserves the integrity of the fabric and the absorbent layers. Machine drying can be used, but always on a low heat setting to avoid damage.

To speed up the drying process, place your period underwear on a drying rack in a well-ventilated area. Avoid direct sunlight as it can weaken the fabric over time.

Natural Stain Removing Techniques

Nothing is more irritating than a pesky period stain you can’t eliminate. Here are a few options to get period stains out.

Baking Soda Paste

Create a paste using baking soda and water. Apply it to the stain and let it sit for 30 minutes. Scrub gently with a soft brush and rinse with cold water. Baking soda is a natural and effective stain remover.

Lemon Juice

Lemon juice has natural bleaching properties. Apply fresh lemon juice to the stain and let it sit in the sun for a few hours. 

If you prefer commercial products, look for ones specifically designed for delicate fabrics. Always follow the instructions on the label.

Dealing with Odors

To prevent odors, rinse your period underwear immediately after use and wash them regularly. Using an odor-neutralizing detergent can also help. For stubborn odors, soak your period underwear in a solution of cold water and white vinegar for 30 minutes before washing.

However, if you notice any signs of wear and tear, such as thinning fabric or reduced absorbency, it’s time to replace them.
