The first thing you should do is set aside 30 minutes and take EVERYTHING out of your car. Then only put back the items you need and use on a frequent basis. This alone with help cure most of the clutter issue. After doing this, we suggest keeping the following in your car to help keep the chaos contained:
1. Clean up kit – trash bags, wipes, Kleenex, and hand sanitizer
2. Empty plastic tote – to contain items and help keep the ‘stuff’ in one place
3. Weather/Emergency kit – just in case. Put in the kit what is needed for your part of the country (e.g. ice scraper, blanket, earthquake items). See ready.gov as well for ideas of what to include.
