Stain on your laptop sleeve or bag? Spot-clean and air-dry first
Machine washing can damage coatings on some laptop sleeves. Remove the computer, check material-specific care instructions, spot-clean where permitted and air-dry completely.
tomtoc advises against machine washing its coated sleeves and recommends shade drying. Samsonite recommends mild soap and water for spot cleaning soft luggage. These are brand- and material-specific examples, not universal care rules.
