The Following is a Guide for How to Wash a Kanken Backpack

Things you will need: A dirty Kanken backpack, bathtub or large sink, mild (non-bleach) detergent, old toothbrush, towels, large hanger.

The Short Version:

  1. Remove all items from the backpack
  2. Take a dry paper towel and remove most of the dirt or gunk
  3. Take wet towel (water only) wipe down remaining interior pockets to remove remaining dirt
  4. If Needed: Run tub or sink with clean water and submerge bag – gently use old toothbrush to scrub areas that are still dirty
  5. If Still Needed: Use OxiClean™ (very little) or other gentle detergent (the non-bleach kind) to soak the bag & repeat scrubbing with the toothbrush
  6. Drain tub and refill with clean water to re-submerge backpack for rinse (repeat this 2 to 3 times)
  7. Use large hanger and hang to dry – inside for best results

OK, let’s go through those step by step.

Step 1 – Clean Out the Backpack

First things first, guys.  Before you can “clean” your bag, you need to “clean out” your bag.  This means opening every single pocket and compartment to make sure you don’t miss anything.  The last thing you want to end up with is a clean backpack, but a ruined cell phone or a soggy piece of paper with that phone number no longer readable…

Tip: This is also a great time to reorganize your backpack.  Sometimes our bags get cluttered like our wallets.  Cleaning them out is a great opportunity to decide what actually goes back in.

Step 2 – Keep Things Dry to Start

Initially, you’ll want to use a dry paper towel (or regular towel) to remove most of the grit and grime that can be seen.  By removing most of the dirt when it’s dry, you’ll avoid creating a mud-like substance that can make things worse than before you started.

Tip: It’s a good idea to turn the bag upside down and physically shake the bag after you’ve done this.  This will get out that hard to reach stuff that’s in the crevices.

Step 3 – Wipe the Bag Down

At this point, hopefully you’ve gotten most of the dirt out of your backpack.  If there’s still any visible dust or dirt, repeat the shaking process to get rid of most of it.  Even with all the shaking and wiping, there will still be dirt inside the pockets.  You’ll want to wet a paper towel or rag (with water only) and wring it out.

Begin wiping the interior down.  We usually like to wipe down 2 to 3 times, then re-soak the rag and wring out to clean it, or get fresh paper towel.  Complete this process for the interior first, making sure to follow each seam (thats where the less-visible grime builds up), then move on to the exterior of the bag.

Tip: Don’t be afraid to rinse the rag out frequently during the cleaning.  You don’t want to just move dirt around, but rather trap it on the rag and move it to the water.

Step 4 – Soak the Bag

Some of you can stop at the step above (if your backpack isn’t too dirty).  But for some of us, we’ll need to clean it a bit more thoroughly. Run some tepid water in your bathtub or sink (the bathtub works easiest, in a sink the bag likely won’t fully submerge so you’ll need to keep turning it around to submerge different sections).

Refrain from using soap at this point.  Ideally, we want to clean the backpack without having to resort to any chemicals or soaps.  You never know how they’ll interact with your bag, so it’s always safest to wash it as conservatively as possible.

With the tub full enough to completely cover the bag, make sure all the pockets are open and submerge the entire bag in the water.  Gently use your hands to shake the bag to loosen any dirt that remains.  It’s also a good idea to have an old toothbrush on hand to scrub any areas that may need it.

What material are laptop bags made from? Laptop bags are available in different materials and styles. Some are sleeve-like cases with protective padding, while others are larger carriers with straps or handles.  The bag style that works best for me might not be the ideal choice for you. However, we probably both agree that the bag has to be strong and durable. It needs to secure and protect the laptop and stand up to daily use.  Luckily, there is a way to measure how strong your bag's material is. What is a Denier rating? The denier rating measures the strength of thread or fiber in a fabric. Technically, the numerical rating is the mass (in grams) of 9,000 meters of a single strand of thread in the fabric.  Though other factors can play a role in the overall strength of a type of fabric, the denier rating is a good indicator of density and durability. The rating is written with a numeral followed by the letter D. So if you see 600D, you know that the material has a denier rating of 600. Technically, this means that 9,000 meters of thread in the fabric weighs 600 grams. The larger the number, the heavier the material and typically the stronger the material. What is a good denier rating? Lightweight bags and backpacks are often around 300D-450D, with heavier-duty options coming in at 600D or above.  With the denier rating in mind, here is a look at the most common types of laptop bag material and how they compare.
Submerge The Backpack

Tip: After you submerge the bag, check to make sure you don’t have any air bubbles remaining and that everything is good and soaked.

Step 5 – Less is More

99% of you will have a clean bag at this point, so we recommend proceeding to the final step.

For those of you that have some stubborn stains that water just won’t remove (coffee or red wine for instance) it’s time to bust out the OxiClean™ or a similar gentle cleaner.

Please, please, please make sure your cleaner DOES NOT contain any bleach.  We feel as though there’s no need for an explanation, but let’s just say your red bag will be pink if you get bleach involved.

Again, you’ll want to run a tub full of tepid water.  Go ahead and add some cleaner.  The key here is that less is more.  You don’t want to end up with a sudsy mess.  It’ll do its job, but you may never get it all out of the bag. 

We’ve found success with as little as 1-2 teaspoons of powdered detergent.  Stir it around so the detergent is thoroughly dissolved, with no grit at the bottom of the tub (that’s guaranteed to end up in a crevice in the bag somewhere).

At this point, you’ll want to submerge the bag like you did above.  Get it to a point where the stained area will remain submerged in the water.  Let it soak for 4-12 hours depending on how bad the stain is.

Use your best judgement here, but you can usually tell if it’s going to take care of the stain pretty quickly by checking it after 30 minutes or so.  Don’t be afraid to use your fingers to gently rub on the stain to see if it’s making any positive progress.

Tip: After the bag has been soaking for several hours, hit each stain with a toothbrush to help loosen, then re-soak.

Step 6 – Rinse, Rinse, Rinse

Now that your bag is clean, you want to make sure that all the soapy residue is gone.  The simplest way to get rid of it is to refill the tub with clean water and submerge the backpack again.  Repeat this process until all of the soapy residue is gone.

Tip:  You’ll be able to tell all the soap is gone when the water stays clean after 3-5 minutes of agitating the clean bag under the water.  If bubbles are still showing up, keep starting the process over until there are no more bubbles or residue on the surface of the water.

Step 7 – Hang and Forget

Dry the bag upside down

You’ll want to hang your backpack upside down to allow any remaining water to drain out to expedite drying.  This might sound odd, but you’ll actually want to dry your backpack as slowly as you possibly can. 

Tip: Use the arm straps of the bag to hang it upside down on a hanger.  If your hanger is large enough, you can hang using both straps, but if not, one strap will work just fine.

24-36 hours should usually do the trick, but we don’t like to hang it outside because it can cause the bag to dry rather quickly – which can result in some parts of the backpack shrinking.

You DEFINITELY want to AVOID using a dryer or hairdryer to dry the bag (see the FAQ below)

A Quick Word on Materials

Let’s talk about materials for a moment. Kanken backpacks are made from mix of natural and synthetic materials, but the key one is something called Vinylon F.

This has been a key feature of the Kanken backpack for years, and its reaction to getting wet (the fibers swell) makes it naturally rainproof (i.e. you don’t need a coating of any harsh chemicals).

These materials are also part of the reason we can clean a Kanken backpack without any harsh cleaning products.
