Quick answer
Clean your waterproof laptop case with mild soap and water, then air dry. Regular maintenance preserves the fabric and zippers.
Why regular care matters for waterproof materials
Waterproof laptop cases, like those made from Rains' signature PU fabric, are designed to resist water and daily wear. But dirt and oils can gradually break down the coating, reducing its effectiveness. A quick clean every few weeks keeps the material supple and the zippers moving smoothly.
Step-by-step cleaning and maintenance guide
- Empty and shake out your case: Remove your laptop and any loose items. Turn the case upside down and shake it to dislodge crumbs, dust, or debris from the corners and lining. Skipping this can grind dirt into the fabric during cleaning, causing scratches.
- Spot-clean stains with mild soap: Mix a few drops of mild dish soap with lukewarm water. Dip a soft cloth or sponge into the solution, wring it out well, and gently dab any visible marks on the exterior and lining. Avoid soaking the fabric. Using harsh chemicals or scrubbing too hard can damage the waterproof coating.
- Rinse with a damp cloth: Wipe the cleaned areas with a cloth dampened with plain water to remove any soap residue. Soap left on the fabric can attract dirt and degrade the material over time. Residue build-up is a common cause of sticky zippers and dull fabric.
- Air dry completely before storing: Hang the case open in a well-ventilated area away from direct heat or sunlight. Let it dry fully—usually 12–24 hours—before putting your laptop back inside. Storing a damp case can lead to mildew and odor inside the lining.
- Lubricate zippers as needed: If the zipper feels sticky or hard to close, apply a tiny amount of silicone-based lubricant or beeswax to the teeth. Wipe off any excess with a dry cloth. Oil-based lubricants can attract dust and may damage the zipper tape.
