Frequently Asked Questions
How do I stop sand from getting into trunk carpet?
Contain sand at the source: put sandy items in a sealed or lined compartment (waterproof organizer, plastic bin or garbage bag) before they touch carpet. Use organizers with smooth, wipeable interiors or removable liners and shake sand out over the beach before loading whenever possible.
Can I store wet swimsuits and towels in my trunk without causing mildew?
Short-term storage (a few hours) in a ventilated or partially open container is usually fine, but avoid sealing heavily wet items for long periods. Use organizers with breathable pockets or ventilated lids, remove and hang items to dry as soon as possible, and clean the organizer regularly to prevent mildew.
What’s the easiest way to clean sunscreen and saltwater spills in the trunk?
For coated fabric organizers and molded trays: wipe up excess immediately, rinse with fresh water to remove salt, and use a mild detergent for greasy sunscreen stains. For carpeted trunk areas, blot liquids quickly, rinse with a damp cloth and use an upholstery cleaner if residue remains; follow with drying to prevent odors.
