How to Clean COS Quilted Bags Step by Step
Step 1: Preparation
The first step in the journey to a cleaner COS quilted bag is preparation. Begin by gathering all the necessary supplies. Lay them out neatly on a flat surface so that everything is within easy reach. This setup will save you time and reduce the risk of overlooking any critical steps.
Step 2: Know Your Material
Don’t rush into cleaning your bag without first understanding its material. Find the care label usually stitched inside the bag.
This label will not only indicate the material but will also provide valuable cleaning instructions, such as whether the fabric is water-resistant or whether it should be dry cleaned. Knowing this information is crucial to avoid causing irreversible damage.
Step 3: Cleaning the Interior
Once you are sure of the material, you can get into the cleaning process…
Emptying the Bag
Start by emptying your COS quilted bag of all its contents, including any zippered or hidden compartments. Make sure to check carefully so you don’t miss any items that could potentially get wet or damaged during the cleaning process. Set these items aside in a safe place.
Turning the Bag Inside Out
Once empty, proceed to gently turn the bag inside out. Doing this allows you to fully access the interior lining, making it easier to clean every nook and cranny. If your bag’s design makes it difficult to turn completely inside out, that’s okay. Do the best you can without forcing it or causing damage.
Preparing the Cleaning Cloth
Take a soft cloth and dampen it with water. Be sure to squeeze out any excess water to avoid oversaturation. Next, add a small amount of mild soap to the damp cloth. Baby soap or other gentle, non-abrasive soaps are ideal for this purpose.
Cleaning Process
With your prepared cloth, begin wiping down the interior lining of your bag. Use soft, gentle strokes and pay special attention to any visible stains, dirt spots, or discolorations. Remember to avoid scrubbing forcefully, as this can damage the material and may cause the stain to spread.
Final Rinse
After you’ve wiped down the entire interior, take a separate soft cloth that is moistened only with water. Use this cloth to go over the interior surface once more to ensure that you remove any leftover soap residue. Soap residue can attract more dirt if left unattended, so this step is crucial.

Step 4: Cleaning the Exterior
Once the interior is spotless, your next focus is the exterior…
Preparation and Dusting
Before you dive into cleaning the exterior, take a soft-bristled brush and lightly sweep it over the surface of the bag. This step helps to remove any loose dust or dirt that might be clinging to the fabric or leather. This is particularly useful for quilted materials, which tend to trap dust in their grooves.
Creating the Cleaning Solution
In a bowl or basin, mix a small amount of mild soap with water to create a cleaning solution. The ratio doesn’t have to be precise; a teaspoon of soap in a cup of water should suffice. Stir until the solution becomes sudsy.
Cleaning the Exterior
Take a new soft cloth and dampen it in the cleaning solution you’ve just prepared. Start wiping down the exterior of your COS quilted bag with gentle, circular motions. Concentrate especially on areas that appear stained or visibly dirty.
Removing Soap
Once you’ve gone over the entire exterior, it’s time to remove the soap. Take a clean, damp cloth—this should be moistened only with water—and go over the surface to remove any lingering soap residue.
Step 5: Drying and Storage
Your COS quilted bag is now clean, but it’s essential to dry it properly. Place it on a drying rack or spread a towel on a flat surface and lay the bag on it. Make sure the bag is in a well-ventilated area but away from direct sunlight, as the sun can fade the fabric.
Let the bag air-dry completely, which might take a few hours. When fully dry, store your bag in a cool, dry place. Keep it away from direct sunlight and areas of high humidity to maintain its condition.

Cleaning your COS quilted bag may seem like a daunting task, but with careful preparation and step-by-step guidance, it’s entirely manageable. Just remember to follow each step diligently and pay attention to the specific care instructions for your bag’s material.
With these best practices, your COS quilted bag will continue to look and feel like new for years to come.
