10 Step-by-step Guidelines on How to Wash Stasher Bags

Step 1: Empty the Bag

First, make sure your Stasher bag is empty of any food or debris. Simply turn it inside out and rinse with water to remove any leftover residue. It’s important to do this as soon as possible after using the bag, as it can make cleaning easier and prevent stains from setting in.

But if you’re in a hurry, don’t worry! Stasher bags are freezer-safe and can hold up to extreme temperatures, so you can simply pop them in the freezer until you have time to clean it properly.

Step 2: Open the Bag

Make sure the bag is open before washing. This will ensure that all parts of the bag get cleaned thoroughly. Otherwise, food particles can get stuck in the folds and crevices of the bag. If you have a stand-up Stasher bag, this step is even more important as the bottom can be easily overlooked if not opened.

It’s also a good idea to separate the seal from the bag while washing, as it will prevent any soap residue from getting stuck and affecting its ability to create an airtight seal.

Step 3: Wash with Soap and Warm Water

Some Dish Soap or Liquid Detergent

Add some dish soap or liquid detergent to warm water in your sink and mix well. Place the Stasher bag in soapy water and use a sponge or brush to scrub the inside and outside of the bag thoroughly. Make sure to get into all corners, crevices, and folds of the bag for a deep clean.

Otherwise, leftover food particles can harden and become difficult to remove later. It’s not recommended to use harsh chemicals or abrasive scrubbers, as they can damage the silicone material and decrease the lifespan of your Stasher bag.

Step 4: Rinse Thoroughly

After scrubbing the bag with soap, rinse it thoroughly with warm water. Make sure there is no soap residue left on the bag as it can affect the taste of your food when you use the bag again. If needed, give it a final rinse with cold water to ensure all the soap is removed.

But remember, always use warm water when washing your Stasher bag. Cold water can make the silicone stiff and difficult to clean. You can also rinse the bag under running water, making sure to get rid of all suds and soap.

Step 5: Air Dry or Use a Clean Towel

There are two ways to dry your Stasher bag after cleaning it – air drying or using a clean towel. If you choose to let it air dry, make sure the bag is completely open and placed upside down on a rack.

This will help any excess water drain out of the bag. You can also use a clean towel to pat it dry. Just make sure the towel is clean, as any dirt or debris can transfer onto the bag.

Step 6: Use a Drying Rack (Optional)

A Drying Rack You Can Place Your Stasher Bag

If you have a drying rack, you can place your Stasher bag upside down on one of its rungs to help it dry faster. This will prevent the bag from being in contact with any surfaces and allow it to dry completely.

If you don’t have a drying rack, simply place the bag open on your counter or use a clean towel. You can prop it open with a spatula or knife to ensure all parts of the bag dry properly.

Step 7: Wash in the Dishwasher (Optional)

Stasher bags are dishwasher safe, making cleaning even easier! Just make sure the bag is placed upside down on the top rack and that all parts of the bag are opened for proper detergent flow.

Also, avoid placing any sharp objects or utensils near the bag, as they can cause punctures. Additionally, don’t use the heated dry setting as it can make the silicone brittle and damage your Stasher bag.

Step 8: Don’t Use Abrasive Materials

Avoid using abrasive materials like steel wool or brushes with stiff bristles to clean your Stasher bags. These can damage the silicone and make it weak, causing leaks or tears in the bag. Instead, use soft sponges or brushes with gentle bristles to clean your bags. It’s also advised not to use any harsh chemicals or bleach on the bags as it can affect their durability and safety.

Step 9: Remove Stains

If you have any stains on your Stasher bag, there are a few tricks you can try to remove them. One option is using a paste of baking soda and water applied with a soft brush. Let it sit for a few minutes before scrubbing and rinsing with warm water.

Any Stains on Your Stasher Bag

You can also soak the bag in equal parts white vinegar and water for a few hours before washing it as usual. Although, it’s normal for some foods to leave slight stains on the bags.

Step 10: Store Properly

After your Stasher bag is completely dry, you can store it folded up or flat. Keep them open until they are completely dry to prevent any potential mold or mildew growth. It’s also a good idea to store them in a cool and dry place away from direct sunlight as heat can make the silicone degrade faster.

When not in use, it’s best to store your Stasher bags with the seal separated from the bag to prevent them from sticking together.

Follow these simple steps on how to wash stasher bags and your Stasher bags will be squeaky clean and ready to store all your delicious food! Remember, proper cleaning and maintenance is key to ensuring the longevity of your Stasher bags. With a little care, they can last for years and help reduce single-use plastic waste in our environment. Happy washing!

Do You Need to Use Professionals?

No, you do not need to use professionals to wash your Stasher bags. With the right cleaning materials and a little bit of time, you can easily clean your Stasher bags at home. It’s also more cost-effective and environmentally friendly to wash them yourself rather than sending them out for professional cleaning.

Just follow these easy guidelines and enjoy using your Stasher bags again and again! So, make sure to follow these steps to keep your Stasher bags clean and in top condition for all your food storage needs. Happy washing!
