Can You Wash a Backpack?

You can wash most backpacks in the washing machine. However, look for machine washability signs on the instructional tag. Some tags give instructions to clean the backpack with hands only.

Checking the wash instruction tags is essential for learning how to wash backpacks.

You can also judge the backpack by reviewing the material if you have some experience.

Some backpacks come with instruction manuals.

You can find the instruction about washability in that manual.

Techniques for Cleaning Your Backpack

Most manufacturers allow you to submerge the backpack in water.

Some do not allow it due to specialized backpack material components.

You can check the instructions on how to wash backpacks to prevent fabric damage during washing.

Most manufacturers include these guidelines.

  • Do not wash the backpack in the washing machine at high settings or dry with the rotational dryer.
  • Prevent damage by cleaning the surface with a sponge instead of a hard brush.
  • Never place the backpack in direct sunlight to dry for a long time as UV rays from the sun can damage the backpack fabric.
  • You can clean the zipper with a soft brush to remove dust and avoid damage to the water-resistant coating of the zipper.

Light Cleaning Backpacks

You can lightly clean your backpack after coming back from a short hike.

You keep some points in mind when light cleaning.

  • Remove all the sand from the inner parts by shaking it upside-down.
  • Clean all parts with a soft sponge.
  • Use soap to remove the stains and dirt.
  • Use a wet cloth for soap removal.
  • Keep it ready by putting equipment after drying.

Deep Cleaning Backpacks

It is better to deep clean your backpack if you come from a long hike.

Deep cleaning can also help you increase the backpack’s life.

  • Use a vacuum cleaner to remove all the dirt from the crevices of the backpack.
  • You can wash and clean the hip belt by detaching it from the backpack if there is a detachment option.
  • You can check the manual to detach the frame for deep cleaning.
  • Submerging the backpack in lukewarm water for a few minutes will remove most dirt and debris.
  • You can rinse off all the soap water and allow it to dry for some time.

How to Wash a Backpack by Hand – Step-by-Step Instructions

When it comes to cleaning backpacks, hand washing is the most effective method.

It is possible to damage the protective coatings on some backpacks, such as climbing packs, if you wash them in the washing machine.

You should hand wash leather bags, leather-trimmed bags, or bags with iron-on patches or embroidery.

This method will show you how to hand wash your climbing backpack or any other backpack.

A list of washing materials you will need.

  • Detergent or mild soap
  • Washcloth or a sponge
  • Soft-bristled cleaning brush
  • Towels (use old ones)

1. Step One – Clean Out the Backpack

Before you even start the process, you should empty and detach anything that is in that backpack.

Make sure that you open all the zips, turn them upside down and shake them up to eliminate any grit and rubble. 

It’s a step that you should do patiently and carefully to remove any item that could be damaged by water.

Remember to take off any additional clip-on accessories, metal parts, or removable straps, if possible. 

For the debris, you can use a vacuum cleaner to effectively get rid of them.

Once you finish with the pockets, leave the zippers open. 

2. Step Two – Read the Label Carefully

Mostly, backpacks come with care labels that instruct on how to handle your bag.

They are often located inside your bag along the side seam, near the main zipper compartment, with cleaning instructions that you should follow carefully. 

Not following them will cause a lot of damage to the fabric.

So, the instructions will ensure that you clean the backpack in the required manner.

These care labels on your backpack have recommended details on cleaning and drying your bag to maintain sustainability. 

3. Step Three – Pre-treat any Stains

At times the backpack will have stains that are hard to let go of with just dusting; in such a case, using a grease or stain remover will work magic. 

The stain remover of your choice will get the target dirty spots off, but you should avoid using bleach.

You can spray the remover directly on the affected area and allow it to be on for about 40 minutes, then scrub gently with an old toothbrush to get rid of the most stain residue. 

4. Step Fourth – Fill a Basin with Lukewarm Water

Add around 6 inches of lukewarm water in a basin and avoid hot water; it might damage your backpack fabric.

Then, add some gentle detergent, and begin scrubbing the bag using a soft brush, especially on the spot stains or dirty areas. 

Using a toothbrush is great; you tend to remove the hard-to-reach crevices and ground-in stains.

A sponge is another washing tool that works better on the mesh areas than using a cloth.

Now, you should turn your bag inside-out and clean its interior too.

5. Step Five – Use a Gentle Detergent

Your choice of detergent should be a gentle cleanser, which is free of fragrances or dyes.

Using industrial or harsh chemicals could cause adverse effects on the fabric of your backpack and probably chip off or diminish the efficacy of the waterproof coating on the fabric that protects it from damage. 

It would be best to have a neutral smell on your backpack to avoid smelling the strong detergent since you might trek for hours on end.

The dyes and fragrances might be irritant to your skin. 

6. Step Six – Submerge Your Backpack

You should not fully dip all bags in water; some require you to use lukewarm water to dip the cleaning rag or scrub brush in since the washing instructions forbid submerging. But you can lay out others in water for cleaning. 

You can scrub using a sponge on the inside and outside and brush to remove the zipper’s buildups.

While cleaning, you can alternate using a hand brush and a sponge.

The washing tool you settle for should depend on the fabric of the bag.

For instance, you can use a hand brush on a piece of canvas fabric; if it has a lot of mesh, a sponge is good enough.

The hard-to-reach areas are well cleaned using a toothbrush.

In this process, take the longest time possible until you feel satisfied with the results. 

While cleaning, you should not skip the bag straps.

They tend to be discolored and dirty and could transfer the residue to your skin or clothes. 

7. Step Seven – Rinse Your Backpack

It’s time to rinse your back after doing the most task of getting rid of stains and dirt.

Rinse out the detergent or soap with lukewarm water to remove any soapy residue on the backpack fabric.

Rinse it thoroughly and wring out the most water without causing any damages to its shape.

 Some people will fold it inside a thick towel to soak the excess water to avoid messing with its shape.

You should go ahead and drain the dirty water and replace it with clean water. 

8. Step Eight – Air-dry Your Backpack

After rinsing the water and detergent out of your backpack, you need to take the next step.

Hang your bag outside in the sun and allow it to dry naturally.

While hanging it, ensure that it’s upside down.

Before you unhang it, make sure that it is 100 percent dry for storage.

If you washed the backpack inside a washing machine, you need to submerge it in lukewarm water without detergent a few times to remove all the soap.

You can place the backpack for air drying.

It will take many hours to remove all the moisture from the backpacks.

If you only cleaned the backpack with a wet cloth, you can place it for air drying.

The fabric can also resist dirt accumulation.
