So how do you keep all the different bag materials clean? It really depends on what the bag is made of. Cotton reusable grocery bags and many hemp reusable grocery bags are machine washable and dryer safe—making them the easiest to wash. If your personalized reusable bag is screen printed or dyed in any way, you should wash in cold water for the first few washings. Some polyester reusable grocery bags can be machine washed, but we only recommend machine washing ‘poly-canvas’ bags.
Nonwoven polypropylene reusable bags and recycled PET reusable bags are trickier to clean. Some people do wash these bags in a washing machine, but we don’t recommend it. If you feel you must machine wash these bags, use cold water only and definitely don’t put them in the dryer. However, machine washing shortens the overall lifespan and can ruin them.
We recommend hand washing your non woven polypropylene reusable bags in a sink filled with warm, antibacterial soapy (preferably antibacterial) water. Let them air dry completely, both inside out AND right side out. This ensures all the seams, nooks, and crannies are dry and aren’t retaining any moisture that can turn into mold. Non woven polypropylene bags can also be sprayed down with an antibacterial spray cleaner, but remember to turn the bags inside out and carefully clean the inner seams.
Nylon or poly-nylon reusable bags should be hand washed in warm soapy water and hung to dry—again, inside out and right side out to ensure all the moisture is gone on the inside.
Laminated reusable bags (either laminated polypropylene bags or laminated recycled pet bags) should be wiped down with a wet cloth or “washed” with a disinfectant spray. Other non-fabric reusable shopping bags can also be cleaned this way.
Finally, our best tip: sort and assign specific bags to specific tasks:
