Step-by-Step Guide to Remove Mold from Car Trunk

Start by removing all items from the trunk. Check for any items that may have mold on them and decide whether they can be cleaned or need to be discarded.

2. Vacuum the Trunk

Prepare a cleaning solution. You can use a commercial mold remover or make your own using household items. Here are two effective DIY solutions:

  • Baking soda solution: Mix one tablespoon of baking soda with a cup of water.

Spray the solution generously on the affected areas and let it sit for 10-15 minutes to kill the mold.
