1. Check every pockets
Emptying the pockets of any backpack is the first step in cleaning it. Leave each pocket unfastened, detached, and turned back to front, if conceivable. If you can, remove any clip-on accessories, straps that can be removed, or metal parts.
Run a vacuum nozzle along all seams, both inside and outside, once the backpack is empty to get rid of any dust or debris.
2. Check the instructions
Search for any labels that deal with washing guidelines. The majority of fabric backpacks can be hand- or machine-washed.
3. Clean the straps
Hand-wash the straps in a solution of heavy-duty liquid laundry detergent (such as Tide or Persil) if they need to be cleaned and are removable. These cleansers contain chemicals that fall to pieces the dirt so you can flush it away with warm water. To loosen the soil, soak the straps for 30 minutes before cleaning heavily stained areas with a soft-bristled brush or an old toothbrush. Rinse the straps in cool water and let them air dry. It should not be dried in a clothes dryer.
4. Add backpack into the washer
The backpack should be put in an old pillowcase or a large mesh laundry bag before being washed in warm water with your standard laundry detergent and the gentle cycle of the washer.
5. Make a disinfectant solution
Sometimes, a knapsack needs a serious cleaning to dispose of microbes. Sanitize a pack on the off chance that workout clothes are left in it for a few days. The athlete's foot fungus can easily spread to other surfaces from socks and shoes.1 Avoid using chlorine bleach to disinfect a gym bag or backpack because it can damage the fabric. Choose pine oil or a wipe with disinfectant instead. Combine the disinfectant and warm water in a 1:1 solution.
