Keep your Eastpak Pinnacle Sunday Grey looking fresh with this step-by-step guide. Learn how to clean, dry, and maintain your backpack without damaging it.
Quick answer
To safely clean your Eastpak Pinnacle Sunday Grey, spot clean with mild soap and water, then air dry completely. Avoid machine washing to protect the quilted back panel and shaped shoulder straps.
Why machine washing is risky for this backpack
The Pinnacle Sunday Grey has a quilted back panel and shaped shoulder straps designed for comfort. Machine washing can loosen the padding or distort the shape, making the backpack less comfortable to carry. Spot cleaning preserves these features and extends the life of your bag.
Another reason to avoid the washing machine: the front organizer pocket has multiple compartments and a key clip. Agitation can damage these internal details or cause the clip to snag fabric.
What you'll need
Gather a soft-bristle brush or sponge, mild liquid detergent (like dish soap), a clean microfiber cloth, and a bowl of lukewarm water. Avoid bleach, fabric softener, or harsh stain removers—they can discolor or weaken the fabric.
Step-by-step cleaning process
- Empty and shake out: Remove all items from every compartment. Turn the backpack upside down and shake it to dislodge crumbs, dirt, and debris. Check the front organizer pockets and the key clip area. Common mistake: forgetting the small pockets in the organizer. Debris left inside can stain or attract pests.
- Spot clean stains: Dip a soft-bristle brush or sponge into the soapy water and gently scrub stained areas in a circular motion. Focus on the bottom panel and corners where dirt builds up. Rinse the brush frequently. Checkpoint: test the soap solution on a hidden spot first. Some detergents can fade dark colors.
- Rinse with a damp cloth: Wipe the entire exterior with a clean microfiber cloth dampened with plain water. Remove all soap residue—leftover detergent can attract more dirt and leave a sticky film. Common mistake: using too much water. The padding inside the quilted back panel takes a long time to dry if it gets soaked.
- Air dry completely: Hang the backpack in a well-ventilated area away from direct sunlight or heat sources. Leave all zippers open to allow air circulation inside. Drying can take 24–48 hours depending on humidity. Checkpoint: do not use a dryer or radiator. Heat can warp the shaped shoulder straps and damage the fabric coating.
- Maintain between washes: Wipe the interior with a dry microfiber cloth after each trip. Use a lint roller on the fabric to remove dust and pet hair. Store the backpack in a cool, dry place when not in use. Common mistake: storing the backpack while damp. Mildew can form inside the organizer pockets and on the quilted back panel.
